Space news (December 11, 2015) – 50 million light-years from Earth, in galaxy M100 –

One of the most enigmatic cosmic objects discovered during the human journey to the beginning of space and time, black holes continue to entrance and mystify both astronomers studying them and common people trying to imagine the possibility of such monsters existing. Black holes are also one of the most difficult celestial objects to detect since not even light rays can escape from the strength of their gravitational-embrace, once they travel beyond the imaginary point-of-no-return astronomers call the “event horizon” of a black hole.

Astronomers working with NASA’s Chandra X-ray Observatory, after analysis of additional data provided by NASA’s Swift Gamma-ray Burst Explorer, the European Space Agency’s XMM-Newton spacecraft, and German’s ROSAT Observatory, believe they have evidence to suggest 30-year old supernova remnant SN 1979C could be a black hole.

Supernova remnant SN 1979C shined X-rays steadily during constant observation from 1995 to 2007. This suggests to astronomers either a black hole eating material left over from the supernova or a hidden binary companion feeding hot material to the monster hidden within 

“If our interpretation is correct, this is the nearest example where the birth of a black hole has been observed,” said Daniel Patnaude of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. who led the study.

Astronomers have detected new black holes that existed during the ancient past through gamma-ray bursts (GRBs) associated with them. SN 1979C is listed in a class of supernovae not expected to produce GRBs, which theory predicts could be the most common way to make a black hole.   

This may be the first time the common way of making a black hole has been observed,” said co-author Abraham Loeb, also of the Harvard-Smithsonian Center for Astrophysics. “However, it is very difficult to detect this type of black hole birth because decades of X-ray observations are needed to make the case.

The idea SN 1979C is a young, recently-formed black hole made from the remnants of a star with 20 times the mass of Sol, that went supernova some thirty Earth-years ago, is consistent with present theory. In 2005, a theory was put forth claiming the bright source of X-rays detected steaming from the supernova remnant is powered by a jet emanating from the monster that’s unable to penetrate the thick hydrogen envelope surrounding it.

Astronomers think there could be one other possibility for the identity of SN 1979C. It could be a rapidly spinning neutron star, with an extremely powerful wind of high energy particles. Present theory predicts this would produce the bright X-ray emissions detected during 12 years of constant observation. 

If this is true, this would make this supernova remnant the youngest known example of a celestial object called a pulsar wind nebula. The Crab Nebula is the best-known example of a bright pulsar wind nebula, but we would have to go back over 900 years to view it as a 30-year old. SN 1979C is a lot younger, which is a great opportunity to study one of the most enigmatic, yet difficult to detect celestial objects viewed during the human journey to the beginning of space and time.

It’s very rewarding to see how the commitment of some of the most advanced telescopes in space, like Chandra, can help complete the story,” said Jon Morse, head of the Astrophysics Division at NASA’s Science Mission Directorate.

Study continues

Astronomers will now continue to study SN 1979C, to see if they can determine its identity. No matter it’s true identity or nature, we can expect this celestial object to be one of the most studied examples of a young supernova remnant during recent times.

Space news (July 23, 2015) – 1,400 light-years away in the constellation Cygnus –

Twenty years after proving other planets do exist the human journey to the beginning of space and time draws nearer to finding an Earth-like cradle for a new human Genesis

NASA’s Kepler spacecraft has discovered the first nearly Earth-sized exoplanet orbiting within the habitable zone of a star much like our own Sun. Called Kepler-452b and roughly 60 percent bigger than our home planet, this exoplanet is the smallest planet found orbiting at a distance from its parent star where liquid water could exist.

On the 20th anniversary year of the discovery that proved other suns host planets, the Kepler exoplanet explorer has discovered a planet and star which most closely resemble the Earth and our Sun,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate at the agency’s headquarters in Washington. “This exciting result brings us one step closer to finding an Earth 2.0.

A Star Like Our Sun

Kepler-452b’s parent star is an older cousin to the Sun, a G2 type star approximately 20 percent brighter, 1.5 billion years older, and 10 percent bigger than Earth’s home star.

We can think of Kepler-452b as an older, bigger cousin to Earth, providing an opportunity to understand and reflect upon Earth’s evolving environment,” said Jon Jenkins, Kepler data analysis lead at NASA’s Ames Research Center in Moffett Field, California, who led the team that discovered Kepler-452b. “It’s awe-inspiring to consider that this planet has spent 6 billion years in the habitable zone of its star; longer than Earth. That’s substantial opportunity for life to arise, should all the necessary ingredients and conditions for life to exist on this planet.

A Rocky Exoplanet like Earth?

Kepler-452b is the twelfth exoplanet the human journey to the beginning of space and time has viewed lying within the habitable zone of its parent star. Data collected by both space and Earth-based telescopes indicates planets of this size are often rocky in nature. Indicating the possibility this exoplanet could have an atmosphere and environment that could act as a cradle for a new human Genesis to begin. 

A New Human Genesis!

Humans traveling across spacetime to Kepler-452b would evolve during a voyage lasting thousands or even hundreds of years. Extended hibernation of some type would certainly make the journey easier, but this kind of technology hasn’t been developed. An alternative solution to extended periods living in space during a voyage unlike any humans have undertaken is probably a necessity.

Once we land on Kepler-452b, learning to survive and live on this foreign planet will evolve us once again. Humans are designed to evolve in order to survive living in different environments. We would likely survive as a species, but doing so would change us in ways we can’t begin to imagine.

521 New Candidates for the Exoplanet Zoo

At the same time, NASA released this news it announced the Kepler mission’s discovery of 521 new exoplanet candidates for the exoplanet zoo. 12 of these candidates orbit their parent star within the habitable zone and nine have home stars similar to the Sun in both size and temperature. Great news for the human desire to locate a second Earth to live on. 

We’ve been able to fully automate our process of identifying planet candidates, which means we can finally assess every transit signal in the entire Kepler dataset quickly and uniformly,” said Jeff Coughlin, Kepler scientist at the SETI Institute in Mountain View, California, who led the analysis of a new candidate catalog. “This gives astronomers a statistically sound population of planet candidates to accurately determine the number of small, possibly rocky planets like Earth in our Milky Way galaxy.

NASA space scientists will now take a closer look at each of the exoplanet candidates and specifically the ones lying within the habitable zone of their parent star. There could be a second Earth, a cradle for a new human Genesis, waiting to be discovered. An event that would change the course of human history on planet Earth and the way we view ourselves as cosmic beings.

NASA announced recently the Kepler mission had found another 715 planets orbiting distant stars. Astronomers determined these planets orbit a total of 305 stars, but this total could change after all the facts are in. This points to a lot more multiple planet-star systems, like our own solar system existing in the Milky Way.

Astronomers believe around 95 percent of these newly discovered planets are smaller than Neptune, which is nearly four times larger than Earth. This means Earth-size planets outside our own solar system are a lot more common than astronomers first thought.

“The Kepler team continues to amaze and excite us with their planet hunting results,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington. “That these new planets and solar systems look somewhat like our own, portends a great future when we have the James Webb Space Telescope in space to characterize the new worlds.”

Work still to be done

Astronomers have had two decades to work out a new way to identify planets among the thousands of star systems they examine using the Kepler Space Telescope and other instruments. The initial process involves laboriously doing a planet-by-planet analysis to determine if a candidate is a planet. Astronomers now use a statistical technique, which they apply to star systems they think have more than one planet.

Jack Lissauer, a planetary scientist at NASA’s Ames Research Center, and a team of scientists analyzed star systems they think have more than one planet. All of these planet candidates were initially found in the first two years of the Kepler Mission – May 2009 to March 2011.

The statistical technique they used is called verification by multiplicity and it partly uses mathematical probability to determine if a candidate is a planet. Astronomers have observed that planets tend to be found together while stars like to roam on their own. If they find a candidate has two or more planet candidates, then it’s probably a star, with orbiting planets. Using these statistical technique astronomers were able to find these 715 new planets.

“Four years ago, Kepler began a string of announcements of first hundreds, then thousands, of planet candidates –but they were only candidate worlds,” said Lissauer. “We’ve now developed a process to verify multiple planet candidates in bulk to deliver planets wholesale, and have used it to unveil a veritable bonanza of new worlds.”

At least four of these new planets astronomers believe are only 2.5 bigger than Earth and orbit their home sun at a distance compatible with the possibility of life. Planets that fall within the habitable zone, or goldilocks zone, of their home star, are planets where water could exist in its various forms. Astronomers believe the temperature and conditions on these four planets could be suitable for biological life forms to exist.

The home star of one of these new planets called Kepler-296f, astronomers believe is only half the mass and 5 percent of our own Sun. Kepler-296f astronomers believe is at least twice the size of Earth and they’re wondering if it could be a gaseous world, with a thick soupy atmosphere, or possibly a water planet, with a life-sustaining ocean of water.

What’s next?

“From this study, we learn planets in these multi-systems are small and their orbits are flat and circular — resembling pancakes — not your classical view of an atom,” said Jason Rowe, a research scientist at the SETI Institute in Mountain View, Calif., and co-leader of the research. “The more we explore the more we find familiar traces of ourselves amongst the stars that remind us of home.”

With the latest planets discovered, this puts the total number of planets the Kepler mission has found at around 1,700. Around 961 of these candidates, NASA is sure are planets. One day we will venture out into the unknown of space and land on one of these distant planets. Each planet we discover brings us closer to this day.

Astronomy news (February 26, 2014)

The human journey to the beginning of space and time recently viewed the closest Type IA supernova found during modern times. The new supernova, called SN 2014J, is about 12 million light-years distant in the Cigar Galaxy M82, which is in the constellation Ursa Major.

NASA’s Spitzer Telescope, along with legions of ground-based and orbiting telescopes, are currently peering directly into the heart of this supernova. Spitzer can peer through the dust and other debris between Earth and the new supernova, using specially designed infrared detectors and cameras. Combined with the data from the legions of ground-based and orbiting telescopes, NASA should be able to provide us with a stunning view of SN 2014J.

“At this point in the supernova’s evolution, observations in infrared let us look the deepest into the event,” said Mansi Kasliwal, Hubble Fellow and Carnegie-Princeton Fellow at the Observatories of the Carnegie Institution for Science and the principal investigator for the Spitzer observations. “Spitzer is really good for bypassing the dust and nailing down what’s going on in and around the star system that spawned this supernova.”

First viewed on January 21, 2014, by students and staff from University College London, SN 2014J is a Type IA supernova, which astronomers believe is a binary star system. Type IA supernovae are thought by astronomers to occur due to two possible scenarios. Either a white dwarf star pulls matter from a companion star until it reaches a threshold and explodes, or two white dwarf stars slowly spiral inward toward each other until they collide, creating a supernova explosion.

Type IA supernovae are important because they explode with almost the same amount of energy and with a uniform peak brightness. Astronomers use Type IA supernovae as standard candles, which allows them to measure distances to nearby galaxies more accurately. Further study of supernova SN 2014J will help astronomers understand the processes producing this type of supernova and determine interesting facts concerning other types of supernovas.

NASA astronomers are currently using the Hubble Space Telescope, Chandra X-Ray Observatory, Nuclear Spectroscopy Telescope Array (NuSTAR), Fermi Gamma-ray Space Telescope and Swift Gamma Ray Burst Explorer to take a closer look at supernova SN 2014J.
