Next stop the ocean worlds of Enceladus and Europa
Space news (planetary science: water worlds of the solar system; Enceladus and Europa) –planets and moons around the solar system and exoplanets across the universe covered with water–
The solar system’s awash in water! NASA missions have provided verifiable facts showing ocean worlds and moons exist in our solar system and beyond,other than Earth. Planetary bodieswhere water is locked in a frozen embrace and even flowing beneath miles of ice. Liquid water exobiologists are keen to explore for life forms they would love to meet and get to know a little better during the next phase of the human journey to the beginning of space and time. Watch this YouTube video on NASA’s search for life on the ocean worlds of the solar system.
Papers published bythe journal Science and written by Cassini mission scientists and researchers working with the Hubble Space Telescope indicate hydrogen gas believed pouring from the subsurface ocean of Enceladus could potentially provide chemical energy life could use to survive and evolve. Watch this YouTube videocalled “NASA: Ingredients for Life at Saturn’s moon Enceladus“, itshowsthe proof scientists used to come to these conclusions. Their work provides new insights concerning possible oceans of water on moons of Jupiter and Saturn and other ocean moons in the solar system and beyond.
“This is the closest we’ve come, so far, to identifying a place with some of the ingredients needed for a habitable environment,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at Headquarters in Washington. ”These results demonstrate the interconnected nature of NASA’s science missions that are getting us closer to answering whether we are indeed alone or not.”
Researchers believe they have found evidence indicating hydrogen gas could be pouring out of hydrothermal vents on the floor of Saturn’s moon Enceladus and into these oceans of water. Any microbes existing in these distant waters could use this gas as a form of chemical energy to operate biological processes. By combining hydrogen with carbon dioxide dissolved in this ocean of water in a chemical reaction called methanogenesis, geochemists think methane could be produced which could act as the basis of a tree of life similar to the one observed on Earth.
On Earth, this process is thought to be at the root of the tree of life, and could even be essential, critical to the origin of life on our little blue dot. Life existing on our planet requires three main ingredients, liquid water, a source of energy for metabolic processes, and specific chemical ingredients to develop and continue to thrive. This study shows Enceladus could have the right ingredients for life to exist, but planetary scientists and exobiologists are looking for evidence of the presence of sulfur and phosphorus.
Previous data shows the rocky core of this moon is similar to meteorites containing these two elements, so they’re thought to be chemically similar in nature, and scientists are looking for the same chemical ingredients of life found on Earth, primarilycarbon, nitrogen, oxygen, and of course hydrogen, phosphorus, and sulphur.
“Confirmation that the chemical energy for life exists within the ocean of a small moon of Saturn is an important milestone in our search for habitable worlds beyond Earth,” said Linda Spilker, Cassini project scientist at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
Cassini detected hydrogen in plumes of gas and frozen matter spewing from Enceladus during the spacecraft’s deepest pass over its surface on October 28, 2015. This combined with previous data obtained by Cassini’s Ion and Neutral Mass Spectrometer (INMS) during earlier flybys around 2005,helped scientists determine that nearly 98 percent of the material spraying from the surface of the moon is water. The remaining two percent is thought to be around 1 percent hydrogen with some carbon dioxide, methane,ammonia and assorted unknown molecules in the mix.
Cassini has shown us two independent detections of possible water spewing from the surface of Enceladus. NASA and its partners are currently looking over proposals to send spacecraft to determineif there is an ocean of water beneath its surface by taking a sample. The Europa Life Finder (ELF)is the proposal NASA’s seriously looking at undertaking at this point, but reports indicate a few other proposals are also being discussed.We’ll provide additional information on other proposals as they’re released to media outlets.
“Although we can’t detect life, we’ve found that there’s a food source there for it. It would be like a candy store for microbes,” said Hunter Waite, lead author of the Cassini study.
Two different observations of possible plumes of water spraying from the icy surface of Saturn’s moon Enceladus provides proof hydrothermal activity is occurring beneath. Geophysicists believe hot water is combining chemically with rock and other matter at the bottom of an ocean of water underneath its icy surface to produce hydrogen gas. Hydrogen gas exobiologists think could be used as energy, food of a sort, to sustain life forms exobiologists want to meet and learn more about. A meeting that would change our place in the cosmos, the way we think about the universe, and reality.
Astronomers and researchers working with the Hubble Space Telescope in 2016 reported on an observation of a possible plume erupting from the icy surface of Europa in the same general location Hubble observed a possible plume in 2014. This location also corresponds to the unusually warm region with cracks in the icy surface observed by NASA’s Galileo spacecraft back in the 1990s.This provides evidence this phenomenon could be periodic, intermittent in this region of the moon. Mission planners are looking at this region as a possible location to obtain a sample ofwater erupting from a possible ocean of water beneath its icy surface. Watch this video on Europa.
Estimates of the sizeof this most recently observed plume indicate it rose about 62 miles (~100 kilometers) from the surface of Europa, while the plume in 2014 only reached a height of around 30 miles (50 kilometers).
“The plumes on Enceladus are associated with hotter regions, so after Hubble imaged this new plume-like feature on Europa, we looked at that location on the Galileo thermal map. We discovered that Europa’s plume candidate is sitting right on the thermal anomaly,” said William Sparks of the Space Telescope Science Institute in Baltimore, Maryland. Sparks led the Hubble plume studies in both 2014 and 2016.
One interesting thought’s the plumes and the hot spot is somehow linked. If this is the case, it could mean the vented water’s falling onto the surface of the moon, which would change the structure and chemistry of the surface grains and allow them to retain heat longer than the surrounding region. This location would be a great place to search for the ingredients of life and a possible entry point into an ocean of water beneath.
These observations by the Hubble Space Telescope and future looks enable future space missions to Europa and other ocean worlds in the solar system. Specifically, laying the groundwork for NASA’s Europa Clipper mission, which is setfor a launch sometime in the 2020s.
“If there are plumes on Europa, as we now strongly suspect, with the Europa Clipper we will be ready for them,” said Jim Green, Director of Planetary Science, at NASA Headquarters.
NASA has indicated they’re looking to identify a possible site with persistent, intermittent plume activity as a target location for a mission to Europa to explore using its powerful suite of science instruments. Another team’s currently at work on a powerful ultraviolet camera to add to the Europa Clipper that would offer data similar to that provided by the Hubble Space Telescope, while some members of the Cassini team areworking on a very sensitive, next generation INMS instrument to put on the spacecraft.
Water’s the story of life on Earth! Science has shown it played and plays the main part in the birth,evolution, and sustenance of life on Earth.
NASA’s planning on taking the human journey to the beginning of space and time to the ocean worlds of the solar system during the decades ahead. To search for the ingredients of life and even possibly simple one-celled life forms, of an unknown type. We plan on going along for the ride to have a look for ourselves and we hope to see your name on the ship manifest. We’ll save a seat for you.

To study ways to protect future astronauts as they prepare and one day travel to the other planets and throughout the solar system
Space news (NASA initiatives: The Transitional Research Institute (NTRI); researching and developing innovative approaches to decrease risks for humans associated with traveling and living in space) – Texas Medical Center Innovation Institute in Houston, Texas –
During the next few decades human beings will travel to parts of the solar system never visited before and the journey is expected to be dangerous, yet awe-inspiring. In order to reduce the risks associated with traveling and living in space, NASA has announced the formation of a partnership with Baylor College of Medicine in Houston. Plans are to operate a new institute charged with researching and developing innovative approaches designed to help keep astronauts alive and healthy during long-term voyages to Mars and beyond.

Called the NASA Transitional Research Institute (NTRI), the new institute will implement a bench-to-spaceflight strategy. Their main goals to produce new treatments, countermeasures, and technologies with practical applications towards known spaceflight health risks. Medical problems like visual impairment intracranial pressure (VIIP) Syndrome, which was identified in 2005, and is currently NASA’s number one spaceflight-related health risk for astronauts. Plans are for the work to be done at the Texas Medical Center Innovation Institute in Houston, Texas.
“It’s fitting on the 47th anniversary of humanity’s first moon landing that we’re announcing a new human spaceflight research institute that will help reduce risks for our astronauts on the next giant leap – our Journey to Mars,” said Marshall Porterfield, NASA’s director of Space Life and Physical Sciences Research and Applications.
Time to get to work
Astronauts will be happy to hear this news and it has the potential to enable mankind’s journey to Mars and beyond to the beginning of space and time. The NASA Transitional Research Institute willhelp form relationships between scientists and medical laboratories and institutes looking to reduce health risks and performance barriers for humans traveling and living in space. It will also keep astronauts healthier during their space missions during the decades ahead.
Giving us a rare, unique window into the environment and emission history of the strongest magnets in the cosmos
Space news (astrophysics: wind nebulas; Swift J1834.9-0846) – 13,000 light-years toward the constellation Scutum in the midst of a vast cloud of high-energy, particles surrounding supernova remnant W41 –
Astronomers studying the strongest magnets discovered during the human journey to the beginning of space and time, magnetars, have detected one they haven’t seen before.A magnetar, a rare highly magnetic neutron star with a vast cloud of high-energy, recently-emitted particles called a wind nebula streaming from it. Offeringa unique window into the characteristics, environment and emission history of one of the most enigmatic and eye-opening objects ever detected.
“Right now, we don’t know how J1834.9 developed and continues to maintain a wind nebula, which until now was a structure only seen around young pulsars,” said lead researcher George Younes, a postdoctoral researcher at George Washington University in Washington. “If the process here is similar, then about 10 percent of the magnetar’s rotational energy loss is powering the nebula’s glow, which would be the highest efficiency ever measured in such a system.”
An object around 13 miles (20 kilometers) in diameter, or about the length of Manhattan Island, only 29 magnetars have been detected, so far. In this particular case, the source of detected emissionsis called Swift J1834.9-0846, a rare type of ultra-magnetic neutron stardetected by the Swift Gamma-ray Burst Satellite on August 7, 2011. It was subsequently looked at closer a month later by a team led by Younes using the European Space Agency’s (ESA) XMM-Newton X-ray Observatory. It was at this time astronomers realized and confirmed the first wind nebula ever detected around a magnetar.
“For me, the most interesting question is, why is this the only magnetar with a nebula? Once we know the answer, we might be able to understand what makes a magnetar and what makes an ordinary pulsar,” said co-author ChryssaKouveliotou, a professor in the Department of Physics at George Washington University’s Columbian College of Arts and Sciences.
Neutron stars are the crushed cores of massive stars left over after they have gone supernova and the densest objects astrophysicists have been able to directly observe during the human journey to the beginning of space and time. All neutron star magnetic fields detected, so far, are 100 to 10 trillion times stronger than Earth’s, and magnetar fields reach levels thousands of times stronger. Astrophysicists have no ideas on howmagnetic fields of such immense strength are formed.
“Making a wind nebula requires large particle fluxes, as well as some way to bottle up the outflow so it doesn’t just stream into space,” said co-author Alice Harding, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We think the expanding shell of the supernova remnant serves as the bottle, confining the outflow for a few thousand years. When the shell has expanded enough, it becomes too weak to hold back the particles, which then leak out and the nebula fades away. This naturally explains why wind nebulae are not found among older pulsars, even those driving strong outflows.“
“The nebula around J1834.9 stores the magnetar’s energetic outflows over its whole active history, starting many thousands of years ago,” said team member Jonathan Granot, an associate professor in the Department of Natural Sciences at the Open University in Ra’anana, Israel. “It represents a unique opportunity to study the magnetar’s historical activity, opening a whole new playground for theorists like me.”
Astrophysicists think a magnetar outburst’s powered by energy stored in itssuper-strong magnetic fieldproduced gamma rays and x-rays, along with the gales of accelerated particles making up the nebulawind detected in the case of Swift J1834.9-0846. Now, they have a mystery to figure out, and new theories to deduce to explain the way a magnetar produces anebula wind.
By studying lightechoes, rings of x-rays observed around binary star system Circinus X-1
Space news (astrophysics: measuring distances of objects; light echoes) – 30,700 light-years from Earth in the plane of the Milky Way Galaxy, observing X-rays emitted by a neutron star in double star system Circinus X-1 reflecting off massive, surrounding clouds of gas and dust –
Determining the apparent distance of objects tens of thousands of light-years from Earth across the breadth of the Milky Way was a difficult problem to solve duringthe early days of the human journey to the beginning of space and time. During the years since these early days, astronomers have developed a few techniques and methods to help calculate distances to stellar objects on the other side of the galaxy.
The most recently measured distance to an object on the other side of the Milky Way used the newest method developed. By detecting the rings from X-ray light echoes around the star Circinus X-1, a double star system containing a neutron star. Astronomers were able to determine the apparent distance to this system is around 30,700 light-years from Earth.
“It’s really hard to get accurate distance measurements in astronomy and we only have a handful of methods,” said Sebastian Heinz of the University of Wisconsin in Madison, who led the study. “But just as bats use sonar to triangulate their location, we can use the X-rays from Circinus X-1 to figure out exactly where it is.”
The rings are faintechoes from an outburst of x-rays emitted by Circinus X-1 near the end of 2013. The x-rays reflected off of separate clouds of gas and dust surrounding the star system, with some being sent toward Earth. The reflected x-rays arrived from different angles over a three month period, which created the observed X-ray rings. Using radio data scientists were able to determine the distance to each cloud of gas and dust, while detected X-ray echoes and simple geometry allowed for an accurate measurement of the distance to Circinus X-1 from Earth.
“We like to call this system the ‘Lord of the Rings,’ but this one has nothing to do with Sauron,” said co-author Michael Burton of the University of New South Wales in Sydney, Australia. “The beautiful match between the Chandra X-ray rings and the Mopra radio images of the different clouds is really a first in astronomy.”
In addition to this new distance measurement to Circinus X-1, astrophysicists determined this binary system’s naturally brighter in X-rays and other light than previously thought. This points to a star system that has repeatedly passed the threshold of brightness where the outward pressure of emitted radiation is balanced by the inward force of gravity. Astronomers have witnessed this equilibrium more often in binary systems containing a black hole, not a neutron star as in this case. The jet of high-energy particles emitted by this binary system’s also moving at 99.9 percent of the speed of light, which is a feature normally associated with a
The jet of high-energy particles emitted by this binary system’s also moving at 99.9 percent of the speed of light, which is a feature normally associated with a relativistic jet produced by a system containing a black hole. Scientistsare currently studying this to see if they can determine why this system has such an unusual blend of characteristics.
“Circinus X-1 acts in some ways like a neutron star and in some like a black hole,” said co-author Catherine Braiding, also of the University of New South Wales. “It’s extremely unusual to find an object that has such a blend of these properties.”
Astronomers think Circinus X-1 started emitting X-rays observers on Earth could have detected starting about 2,500 years ago. If this is true, this X-ray binary system’s the youngest detected, so far, during the human journey to the beginning of space and time.
This new X-ray data is being used to create a detailed three-dimensional map of the dust clouds between Circinus X-1 and Earth.
Astrophysicists are preparing to measuredistances to other stellar objects on the other side of the Milky Way using the latest distance measurement method. This new astronomy tool’s going to come in handy during the next leg of the human journey to the beginning of space and time.
Traveling at 250,000 mph would be a windy, visually spectacular ride to hell
Space news (Astrophysics: stellar nursery dynamics; runaway stars) – 170,000 light-years from Earth, near the edge of the Tarantula Nebula –
If you want to travel through the galaxy, hitch a ride on a runaway star like the one astronomers have been tracking since it came screaming out of 30 Doradus (Tarantula Nebula) in 2006. Data collected by the newly installed Cosmic Origins Spectrograph on the Hubble Space Telescope suggests a massive star, as much as 90 times the mass of Sol, was knocked out of the nebula by gravitational interactions with even more massive suns. Traveling at around 250,000 mph, voyaging through the cosmos on this runaway star would be an adventure to write home about.
The trail leads back to a star-forming region deep within the Tarantula Nebula called R136, where over 2,400 massive stars near the center of this huge nebula produce an intense wind of radiation. Astronomers think interactions with some of the 100 plus solar mass stars detected in this stellar nursery resulted in this runaway star being flung over 375 light-years by its bigger siblings.
“These results are of great interest because such dynamical processes in very dense, massive clusters have been predicted theoretically for some time, but this is the first direct observation of the process in such a region,” says Nolan Walborn of the Space Telescope Science Institute in Baltimore and a member of the COS team that observed the misfit star. “Less massive runaway stars from the much smaller Orion Nebula Cluster were first found over half a century ago, but this is the first potential confirmation of more recent predictions applying to the most massive young clusters.”
Astrophysicists studying the runaway star and the region in the Tarantula region where the trail ended believe it’s likely a massive, blue-white sun at least ten times hotter than Sol and only a few million years old. It’s far from home and in a region of space where no clusters with similar stars are found. It’s also left an egg-shaped cavity in its wake with glowing edges pointing in the direction of the center of 30 Doradus and the region of R136. A flaming trail you would see behind the star as you traveled across the cosmos and onto eternity.
“It is generally accepted, however, that R136 is sufficiently young, 1 million to 2 million years old, that the cluster’s most massive stars have not yet exploded as supernovae,” says COS team member Danny Lennon of the Space Telescope Science Institute. “This implies that the star must have been ejected through dynamical interaction.”
This runway star continues to scream across the cosmos, nearing the outskirts of 30 Doradus a star-forming region in the Large Magellanic Cloud, it will one day end its existence in a titanic explosion or supernova, and possibly leave behind one of the most mysterious and enigmatic objects discovered during the human journey to the beginning of space and time, a black hole.
Imagine riding this runaway star until it contracted into a black hole and left our universe altogether. Where would we travel? To a random location in spacetime? To another reality or universe? The possibilities abound and far exceed our ability to imagine such a reality. Scientists tell us such a journey wouldn’t be possible, but they’re just stumbling around in the dark looking for ideas to grasp. For handholds on the dark cliff we climb as we search for answers to the mysteries before us.
Astronomers continue to study the Tarantula Nebula and the star-forming region R136 looking for signs of impending supernovae among the zoo of supermassive stars within. They also continue to track this runaway star and two other blue hot, supermassive stars outside the boundary of 30 Doradus that appear to have also been ejected from their host systems. We’ll update you with any news on it, and other runaway stars as it continues to scream across the cosmos.
A symbol for war and aggression for human tribes for thousands of years, fear and foreboding grew in the heart whenever a blood-red star, Mars (the Red Planet) appeared and moved across the night sky.
Space & Astronomy Wiki – the planets of the solar system –
With 11 percent of the mass and half the diameter of Earth, Mars is smaller than Venus and bigger than both Mercury and the Moon. A world of geological wonders, with ancient volcanoes dwarfing the biggest mountains on Earth, the Red Planet had warm and wet geological periods in the distant past.
The most studied of the nine planets besides Earth, Mars is the fourth planet from the Sun at an average distance of 142 million miles and is named after the Roman God of War.
Tuesday was Mars Day in ancient Babylonia, who first created the seven-day week because they believed on this day Mars influenced their lives. With two small moons called Phobos and Deimos, that look much more like asteroids from the Main Asteroid Belt, and a surface that looks Earth-like in photographs, the Red Planet is probably the best planet to terraform.
Mars has an atmosphere primarily composed of carbon dioxide, with a little water vapor, and not enough oxygen for you to breath. With a gravity field .375 of Earth’s and an average surface temperature of -81 degrees Celsius, it will take generations to make the Red Planet habitable for human life.
The 14th biggest constellation in the night sky, Pisces the Fishes is visible in the night sky between latitude 90 to -65 degrees.
Space & astronomy wiki – the constellations in the sky –
Northeast of Aquarius the Water Bearer and Northwest of Cetus the Sea-monster, observers in Canada best look in early Autumn to view this faint, but huge V-shaped constellation occupying 889 square degrees of the 1st quadrant of the Northern Hemisphere.
The best time to see Pisces is around 9 p.m. (10 p.m. local standard time) between November 6-9. This changes to around 8 p.m. during the early days of December.
Look for the celestial signpost most observers use to find Pisces the Fishes, the Great Square of Pegasus as shown in the image below. Look for the Circlet of Pisces – often called the head of the Western Fish – to the south of the Square of Pegasus. Once you locate the Circlet of Pisces, head east of the Square of Pegasus to the Eastern Fish.
One of the first constellations in the night sky to be identified by ancient astronomers, Pisces the Fishes is believed to be based originally on the Syrian goddess of love and fertility Atagartis. Half-fish and half-woman some archaeologists believe Atagartis is the inspiration Babylonian astronomers used to originate both Greek and Roman goddesses of love and beauty Aphrodite and Venus.

The seventh planet from the Sun at 2.9 billion km (1.8 billion miles) or 19.19 AU, Uranus is a world tinted blue due to more methane in its mainly hydrogen and helium atmosphere than a similar gas giant like Mighty Jupiter or Spectacular Saturn.
Space & Astronomy Wiki – the planets in the solar system –
A year on Uranus, the amount of time it takes the planet to orbit the Sun, takes about 84 Earth-years to complete, but a day is only 17 hours in length. 27 moons of various sizes orbit this planet, which is just about the same in size as Neptune, moons name after characters from the works of Shakespeare and Alexander Pope.
Although it’s not as apparent looking at Uranus through a telescope, this light blue world does have a ring system, composed of narrow and dark inner rings and brightly colored outer rings. As you look at this far off world through a telescope, you’ll notice it’s tipped on its side, compared to the other planets. Some planetary space scientists believe this orientation could be due to a collision over 4.5 billions years ago, when the solar system was being formed.
This distant world has only been visited by one man made spacecraft, Voyager 2 flew by Uranus, and the other outer planets, before heading off out of the solar system. The majority of the facts we have concerning this amazing world are due to this flyby, and unfortunately humans presently have no missions to Uranus planned for the future.
Space & Astronomy Wiki – the closest star to Earth –
Worshiped by every recorded human culture, the Sun – or Sol as the Romans called it – contains over 99.8 percent of the mass in the solar system, and is over a thousand times as massive.
Composed of 7.8 percent helium (He) and 92.1 percent hydrogen (H2) along with 0.1 percent oxygen and other elements, Sol looks solid in photographs, but its surface is a sea of hot 5,500 Celsius (10,000 degrees Fahrenheit) gas.
Called ‘Helios’ by the Greeks, the Sun is a stellar type G star called a main-sequence star but will change into a brighter, bigger and cooler red dwarf star around 5 billion years after its birth.
With a diameter over 100 times that of Earth at 1.4 million km (840,000 miles), the Sun is a common medium-sized yellow star you could fit over a million piles of earth inside.
Sitting at a distance of 149.6 million km (93 million miles) from our planet or 1 astronomical unit (AU), a distance which is used as a common measuring stick by astronomers viewing the solar system, the Sun transforms over 600 million tons of hydrogen into 596 tons of helium every second through nuclear fusion.
Dominating the gravity pool of the solar system, the mass of the Sun warps spacetime, which determines the orbits of the planets, and governs the movements of all mass bodies within the boundaries of the system.
June 30 Venus and Jupiter will appear as one big double star in the western sky once the Sun goes down
Space news (June 26, 2015) –
Amateur and professional astronomers are watching as Venus and Jupiter draw steadily closer and will appear to converge on June 30. The two brightest planets in the night sky, Venus and Jupiter have been moving toward convergence since the beginning of the month, which is the closest they’ll appear until August 2016.
Wind the clock back a few thousand years, there would probably be a festival or human sacrifice, in some cultures, about to occur in a few days time. Looking up at Venus and Jupiter as they move closer each night would have been an awe-inspiring and frightening sight, and certainly one an ancient culture would have noticed and worshiped in some way.
Venus and Jupiter are in fact over 800 million miles apart, they only appear closer in the night sky, because of their current positions in their orbits. Venus is currently overtaking or lapping Jupiter as it orbits the Sun, and on June 30 across North America, they’ll appear as one big double star in the night sky.
Viewers can view the convergence with the naked eye although binoculars or a small telescope certainly enhances the show. The best part is the show is viewable anywhere on the planet, check with local astronomers for the best time to view the convergence.
Just look to the West a few hours after sunset on June 30. People in Australia and the East wait until August 1 to see Venus and Jupiter converge, but this won’t diminish the show.
Your eyes will need a few minutes to adapt to light levels, but once the lights go down, you’ll be amazed by the brightness of the event. A stunning 0.33 of a degree apart at convergence, around 30 times closer than at the beginning of the month, Venus and Jupiter can be hidden behind your finger.
There’s nothing to be afraid of, these events don’t significantly increase gravitational forces, and aren’t harbingers of doom.
No need for the human sacrifice!
