Latest Outer Space News, Breaking Headlines

Community FQXb (bio)By WILLIAM OREM • Mar. 23, 2014 @ 21:39 GMT Everyone is talking this week about the dramatic confirmation of inflationary theory: those first-instant gravitational waves whose details may even point--being, if you will, quantum phenomena that went suddenly ultra-macroscopic--toward the correct way to unify QM and GR. I myself have been musing on rather astonishing work in another field. Recently the big news there was released: an unprepossessing experiment involving a weak acid bath showed it's possible to revert mature, differentiated cells to a stem cell state, allowing for the prospect of wholesale repurposing. This is the angle most science journalists gave the discovery last month: "Outsider runs outrageous experiment, stumbles upon success." Alas--you knew this part was coming--it is now looking like the champagne may have been premature. Either way, though, I'm left musing. As a finding, it's counterintuitive. Is this a natural propensity of all cellular life? 1. 2. 3.

Stellarium Failed Star Found In The Neighborhood: Scientific American Podcast It looks like we have a new neighbor. It's actually been there all along, but astronomers have only now spotted what could be the seventh closest star system to the sun. The system is just nine light years away, a mere stone's throw in astronomical terms. It took so long to find because it's an extremely dim and cool kind of failed star called a brown dwarf. Astronomers found it using NASA's WISE satellite. The sun's newfound neighbor and five other supercool brown dwarfs belong to a class of failed star called Y dwarfs. You could safely touch one of the newfound brown dwarfs—its temperature is estimated at about 80 degrees Fahrenheit. Hundreds of possible brown dwarfs are out there awaiting confirmation. —John Matson [The above text is a transcript of this podcast.]

Latest Mars Weather Captioned Image Release No. MSSS-321 — 16 April 2014 Martian weather between 7 April 2014 and 13 April 2014: The MARCI acquires a global view of the red planet and its weather patterns every day. Local dust storms were observed in Solis, Aonia, and west of Syrtis. This week’s MARCI “movie” can be downloaded HERE (9.1 MB .mov file). Earlier Mars Weather Reports are available HERE. About the Quicktime Movie: The movie (a .mov file that you can click and play, above) was generated from images obtained by the Mars Color Imager (MARCI) onboard the Mars Reconnaissance Orbiter (MRO).
