Space news (July 29, 2015) – 1.25 million miles (2 million kilometers) from Earth and headed into the Kuiper Belt

NASA space scientists looking at LORRI images and data sent back to Earth by the New Horizons spacecraft ten days after closest approach to the dwarf planet Pluto received a nice surprise. Exotic ices flowing across the surface of the dwarf planet Pluto as glaciers do on Earth and possibly Mars. Indicating geological activity planetary scientists had dreamed of but didn’t truly expect to find, and the possibility even bodies at extreme distances from the Sun could be crucibles for the ingredients of life.

“We knew that a mission to Pluto would bring some surprises, and now — 10 days after closest approach — we can say that our expectation has been more than surpassed,” said John Grunsfeld, NASA’s associate administrator for the Science Mission Directorate. “With flowing ices, exotic surface chemistry, mountain ranges, and vast haze, Pluto is showing a diversity of planetary geology that is truly thrilling.”

This plain rests within the western half of Pluto's noted heart-shaped feature called Tombaugh Regio and could be rich in nitrogen, carbon monoxide, methane ices, and other compounds.

This plain rests within the western half of Pluto’s noted heart-shaped feature called Tombaugh Regio and could be rich in nitrogen, carbon monoxide, methane ices, and other compounds.

“We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI. “I’m really smiling.”

“At Pluto’s temperatures of minus-390 degrees Fahrenheit, these ices can flow like a glacier,” said Bill McKinnon, deputy leader of the New Horizons Geology, Geophysics, and the Imaging team at Washington University in St. Louis. “In the southernmost region of the heart, adjacent to the dark equatorial region, it appears that ancient, heavily cratered terrain has been invaded by much newer ice deposits.”

Space scientists combined four New Horizon images taken by LORRI with color data from the Ralph Instrument to produce this stunning global view of Pluto taken at a distance of 280,000 miles (450,000 kilometers) from the spacecraft.

Detailed analysis of LORRI images taken of Pluto’s surface reveals a global pattern of ice floe zones varying according to latitude. The darkest surface terrains are found near the equator region, with mid-toned terrains being mainly located in mid-latitudes, and lighter colored terrains covering the North Polar Region.

Mountain Ranges Viewed on Pluto’s Sputnik Planum

Planetary scientists have named the two peaks of the mountain range Hillary Montes (Hillary Mountains) for Sir Edmund Hillary, who along with legendary mountain guide Tenzing Norgay summited Mount Everest in 1953. Rising over 1 mile (1.6 kilometers) above the surface of the planet, image climbing to the top of these peaks, a feat humankind could one day attempt and achieve. This would truly be an inspiring moment during the human journey to the beginning of space and time.

This LORRI image shows the surface terrain of Pluto are much more complicated than planetary scientists first thought. Notice the polygonal shape of many of the plains viewed, two magnificent mountain ranges, and cratered terrain that looks like ice has recently been deposited.

“For many years, we referred to Pluto as the Everest of planetary exploration,” said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado. “It’s fitting that the two climbers who first summited Earth’s highest mountain, Edmund Hillary, and Tenzing Norgay, now have their names on this new Everest.”

Seven hours after reaching its point of closest approach to Pluto, New Horizons looked back at the dwarf planet through its Long Range Reconnaissance Imager (LORRI) just in time to view sunlight beaming through its atmosphere highlight gasses rising as high as 80 miles (130 kilometers) from its surface. Subsequent analysis of images revealed two distinct gas layers, one at around 30 miles (50 kilometers), and the other at 50 miles (80 kilometers).

“My jaw was on the ground when I saw this first image of an alien atmosphere in the Kuiper Belt,” said Alan Stern, principal investigator for New Horizons at the Southwest Research Institute (SwRI) in Boulder, Colorado. “It reminds us that exploration brings us more than just incredible discoveries — it brings incredible beauty.”

“The hazes detected in this image are a key element in creating the complex hydrocarbon compounds that give Pluto’s surface its reddish hue,” said Michael Summers, New Horizons co-investigator at George Mason University in Fairfax, Virginia.

Planetary scientists believe the hazes detected in the LORRI images form through a process in which sunlight breaks up methane gas particles, which have been detected in the atmosphere of Pluto. This process leads to the formation of more complex hydrocarbon gasses, like ethylene and acetylene, which have been detected by New Horizons.  These heavier compounds fall to the lower regions of Pluto’s atmosphere, where they condense into ice particles that form the hazes viewed. The ice particles are then struck by ultraviolet sunlight, which converts them into the dark hydrocarbons covering the surface of the dwarf planet.

This theory is different than first thoughts on the possibility of this process occurring, in fact, space scientists had previously calculated temperatures would be too warm for such hazes to form above the altitude of 20 miles (30 kilometers). It appears they’ll have to devise a new theory for how the hazes detected could form so far from the surface of Pluto.

Presently around 7.6 million miles (12.2 million kilometers) from Pluto and flying deeper into the Kuiper Belt, New Horizons will continue to send data back to Earth through this year and 2016. All involved in the mission expect to discover more and more about dwarf planets, the Kuiper Belt, and the Solar System as the human journey to the beginning of space and time heads into unseen territory searching for the unknown.

Crucible of the Building Blocks of Life

Just add water, gasses, and simple organic molecules 

Space news (July 27, 2015) – the search for life beyond Earth – a simple recipe for extraterrestrial life –

The simple building blocks of life could have traveled to Earth on icy grains of dust carried on asteroids and meteorites during the early moments of the Solar System.
The simple building blocks of life could have traveled to Earth on icy grains of dust carried on asteroids and meteorites during the early moments of the Solar System.

NASA scientists studying the origins of organic compounds important to the development of life on Earth think they’re on the trail of a cosmic “Crucible of the Building Blocks of Life”. Recent experiments conducted by astrobiologists working at the Goddard Space Flight Center in Greenbelt, Maryland indicate asteroids and meteorites could have been the source of complex organic compounds essential to the evolution of life on Earth. Essential organic compounds they have been able to reproduce in laboratory experiments from simpler organic compounds, water, and gasses in simulations of the space environments of meteorites and asteroids. 

“We found that the types of organic compounds in our laboratory-produced ices match very well to what is found in meteorites,” said Karen Smith of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This result suggests that these important organic compounds in meteorites may have originated from simple molecular ices in space. This type of chemistry may also be relevant for comets, which contain large amounts of water and carbon dioxide ices. These experiments show that vitamin B3 and other complex organic compounds could be made in space and it is plausible that meteorite and comet impacts could have added an extraterrestrial component to the supply of vitamin B3 on ancient Earth.”

“This work is part of a broad research program in the field of Astrobiology at NASA Goddard. We are working to understand the origins of biologically important molecules and how they came to exist throughout the Solar System and on Earth. The experiments performed in our laboratory demonstrate an important possible connection between the complex organic molecules formed in cold interstellar space and those we find in meteorites.”

The Crucible of the Building Blocks of Life

Deep within immense clouds of gas and dust created by exploding stars (supernovae) and the winds of red giant stars coming to the end of their days are countless dust grains. Many of these dust grains will end up part of asteroids and meteorites like the millions of bodies in the Main Asteroid Belt, Kuiper Belt, and Oort Cloud. Asteroids and meteorites that bombarded the Earth from space during the formation of the planets and Solar System.

Cosmic dust grains carried on asteroids and meteorites that struck the Earth during the first moments of the birth of the Solar System could have carried complex organic compounds that contributed to the birth and evolution of life on Earth.
Cosmic dust grains carried on asteroids and meteorites that struck the Earth during the first moments of the birth of the Solar System could have carried complex organic compounds that contributed to the birth and evolution of life on Earth.

NASA space scientists were able to reproduce a “Crucible of the Building Blocks of Life” using an aluminum plate cooled to minus 423 degrees Fahrenheit (minus 253 Celsius) as the cold surface of an interstellar dust grain carried by an asteroid or meteorite heading to Earth 4.5 billion years ago. The experiments were conducted in a vacuum chamber used to replicate conditions in space to which they added gasses containing water, carbon dioxide, and the simple organic compound pyridine. Bombarding the cold surface with high energy protons from a particle accelerator to simulate cosmic radiation and other radiation found in space produced more complex organic compounds like vitamin B3.  

Data collected by the European Space Agency's Rosetta Mission during the months and years ahead could shine more light on this subject. Rosetta's lander, Philae, is currently sitting on the surface of Comet 67P/Churyumov-Gerasimenko awaiting its closest approach to the Sun in August 2015. Presently, the surface of the comet is warming and gases we can test to validate the results of these experiments are expected to be released as it nears Sol.

Pluto

Considered the ninth planet for nearly 75 years, the second biggest dwarf planet discovered in the solar system. Pluto was originally given the name of the Greek god of the underworld by 11-year-old Venetia Burney.

Space & Astronomy Wiki – the planets in the solar system –

The furthest of the original nine planets in the solar system from Sol at 3.7 billion miles (5.9 billion km) or 39.5 AU, Pluto is the second biggest dwarf planet behind Eris, which is about 28 percent more massive.

Orbited by moons Charon, Nix, Styx, Kerberos, and Hydra, Pluto was discovered on February 18, 1930, by Clyde W. Tombaugh. Charon is almost 50 percent the size of Pluto and is believed to be the result of a collision between a planet-sized object and the dwarf planet early in the history of the solar system.

If the icy surface of Pluto's giant moon Charon is cracked, analysis of the fractures could reveal if its interior was warm, perhaps warm enough to have maintained a subterranean ocean of liquid water, according to a new NASA-funded study.

With only 12, 173 miles (19, 591 km) between Pluto and Charon, astronomers and space scientists consider the pair to be a double planet system. The entire Pluto system is part of the distant Kuiper Belt, a distant disk-like region beyond the orbit of Neptune full of icy bodies formed during the early history of the solar system.

A day on Pluto is about 153 hours long, which is the time it takes the dwarf planet to spin once on its axis, and a year, the time it takes this distant object it orbit the Sun, takes about 248 Earth years.

The structure of Pluto is not very well understood at present. Nevertheless, spectroscopic observation from Earth in the 1970s has revealed that the planet surface is covered with methane ice. Surface temperature is -230 degrees C, and the frozen methane exhibits a bright coloration. However, with the exception of the polar caps, the frozen methane surface is seen to change to a dark red on the basis of observation of eclipse by its moon Charon.

What are planetary scientists saying?

Some planetary scientists think Pluto could have an ocean hidden beneath its icy surface, but this cold and distant body isn’t thought to be a place life could exist. Scientists estimate this dwarf planet has three times as much water in the form of ice as contained within the oceans of Earth.

How big is Pluto’s atmosphere? This is not a typical question one finds in planetary science. Earth’s atmosphere has an equivalent thickness – the thickness if you compress the atmosphere to uniform pressure and density – of about 10 kilometers, or six miles. Compare this with the radius of Earth, 6,370 kilometers, and you see that the razor-thin thickness of Earth’s atmosphere is about 0.17% of its radius. Even if you consider the “outer limit” of Earth’s neutral atmosphere, what we call the exobase, that reaches about 600 kilometers altitude, the atmosphere’s equivalent thickness is only 10% of Earth’s radius—still very thin. So the volume of Earth’s atmosphere is tiny compared to Earth’s volume. Michael E. Summers is a professor of Planetary Science and Astronomy at George Mason University, and specializes in the study of the chemistry and dynamics of planetary atmospheres. He is a New Horizons co-investigator and member of the atmospheres science theme team.

The surface is also covered by frozen methane and nitrogen gas, which thaws as Pluto nears the Sun, forming a thin atmosphere composed primarily of nitrogen, carbon monoxide, with a little methane thrown in.

To be a Planet, or Not to be a Planet?

Astronomers are constantly rethinking old theories and designing new ones to fit new ideas

Astronomy News – astrophysics: planets; the number and type of planets

Count the planets in the solar system and make an assessment of their various sizes and distances from Sol and the Earth as you leave on your “Journey to the Beginning of Space and Time”. You’ll find that the line between planet and smaller planetoids, like asteroids and meteorites, has yet to be firmly set in place in the astronomy books, and in the universe.

We were all taught during our school indoctrination of nine planets circling Sol at varying distances. Mercury and Venus lie closest to Sol, with the Earth, Mars, Jupiter, and Saturn residing at greater distances from Sol, while Uranus, Neptune, and disputed Pluto orbit at the greatest distance on average as compared to the other planets. Millions of school and reference books, thousands of articles, and countless periodicals also include references to Pluto being officially recognized as the ninth planet in the solar system. The publishers of these publications will be calling for a rewrite of all of this material and the history books will have to be changed if some astronomers and space scientists have their way.

Planet X came spinning into the view of Caltech astronomer Michael Brown on July 29, 2005 and changed the way astronomers and star gazers think about Pluto and the definition of a planet. An icy, Kuiper Belt resident Michael named after Xena the warrior goddess of the famed television series, at least until the International Astronomical Union speaks on this matter, Planet x orbits Sol at a distance nearly twice as great as Pluto’s. Planet X’s 560-year orbit is also inclined to the ecliptic by nearly twice as much as Pluto’s, which results in Planet X being closer to Sol than Pluto during its orbit, at times.

Planet X is still a bit of an enigma to astronomers

Astronomy takes you to the Kuiper Belt
The largest Kuiper Belt objects compared

How much bigger is Planet X than Pluto? Astronomers have measured the brightness and distance of Planet X from Sol, as compared to objects of known brightness in the solar system. Based on their data and calculations, astronomers believe Planet X to be bigger than Pluto, but just how much bigger has yet to be firmly etched in stone by the various astronomical societies and agencies tasked with determining if Planet X is indeed bigger than Pluto and by how much. This fuzzy-news has pushed Pluto into tenth place in the nine planet race in the solar system and into second place in the size ranking of the objects in the Kuiper Belt and astronomers, and star gazers have only searched a small percentage of the Kuiper Belt for objects bigger than Pluto.

Will bigger objects than Planet X be discovered in the Kuiper Belt or somewhere on the outer fringes of the solar system? The first Kuiper Belt objects were viewed by star gazers and astronomers in the early 1990s, but since this time, larger and larger objects have been located in the Kuiper Belt. In 2002, an object half the size of Pluto was discovered floating in the Kuiper Belt, which astronomers named Quaoar. Just two years later, 2004DW and Sedna were discovered, each respectively two-thirds and three-quarters the size of Pluto. It wouldn’t be surprising, therefore, if star gazers and astronomers were to find an even larger object floating in the Kuiper Belt than Planet X at some point in the human “Journey to the Beginning of Space and Time”.

The definition of a planet has changed over the years

Blaze Your Name in the Night Sky

Celestial bodies in the night sky are often named after their discoverers

Astronomy News – Write your name in the annals of the human journey to the beginning of space and time –

Take a look at the night sky above you and name a few of the celestial objects you know in your head. Would you like to leave your name written in the annals of astronomy and human history? One of the greatest honors for an astronomer is to have their name adorn a celestial body in the night sky. Look up into the night sky and many of the stellar bodies you see will have been named in honor of their discoverer, a famous figure in history or science, or will have been given a designation of some type to distinguish them from other stellar bodies. Humans will forever speak of the distant ice balls at the fringe of the solar system we refer to as the Kuiper Belt and Haley’s Comet.

Halley's Comet will be back one day
Halley’s Comet will be seen again in a few years

Astronomy lovers can write their name in the history books

True, the chances of a celestial body in the night sky being named for a particular amateur astronomer is remote, at best, considering the competition and the fact that the decision is made by other powers in the universe. The possibility of this certainly increases for a professional astronomer making a significant discovery, but the final decision is still in the hands of other powers. There are a lot more amateur astronomers looking at the night sky on a nightly basis than professional astronomers, and this fact alone is going to make it likely that amateur astronomers will make significant contributions to the history of astronomy.

It certainly wouldn’t be surprising if a professional astronomer or two have spent a few moments in contemplation of a celestial body being named in their honour or moment in time when they could be making astronomy history. Speculating astronomers might have even gone to the trouble of choosing a name for their discovery. The actual naming of newly discovered celestial bodies is actually conducted by other powers in the world of astronomy.

This doesn’t mean that amateur astronomers aren’t honoured by having their names adorn a celestial body in the night sky. Tom Bopp, an amateur stargazer will forever live on in the minds of humans as the discoverer of the biggest comet of the twentieth century, Hale-Bopp, which was also independently discovered by astronomer Alan Hale.

Hale-Bopp is often very bright in the night sky when it appears
Hale-Bopp’s two tails are in view here

Astronomy is a journey all human beings can take part in

The only way you can hope to leave your name written in the history of astronomy is to spend time watching the night sky above you. Every time you board your time machine to the stars and soar upward and out into the cosmos, you could find something that no human has seen before.

Join me every night as we’ll “Journey to the Beginning of Time and Space” and go on a voyage of discovery that will take us to unknown parts of the universe.
