Helium-Shrouded Planets May Be Common in Our Galaxy Feature15-06_sq Spitzer Space Telescope Thu, Jun 11, 2015

The wacky world of exoplanets continues to surprise astronomers. They wouldn't float like balloons or give you the chance to talk in high, squeaky voices, but planets with helium skies may constitute an exotic planetary class in our Milky Way galaxy.

Astronomers Set a New Galaxy Distance Record Partner091_sq Spitzer Space Telescope Tue, May 05, 2015

An international team of astronomers, led by Yale University and the University of California scientists, pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5 percent of its present age of 13.8 billion years. The team discovered an exceptionally luminous galaxy more than 13 billion years in the past and determined its exact distance from Earth using the combined data from NASA’s Hubble and Spitzer space telescopes, and the Keck I 10-meter telescope at the W. M. Keck Observatory in Hawaii. These observations confirmed it to be the most distant galaxy currently measured, setting a new record. The galaxy existed so long ago, it appears to be only about 100 million years old.

Astronomers Find First Evidence of Changing Conditions on a Super Earth Partner090_sq Spitzer Space Telescope Mon, May 04, 2015

Using NASA’s Spitzer Space Telescope, the researchers observed thermal emissions coming from the planet, called 55 Cancri e – orbiting a sun-like star located 40 light years away in the Cancer constellation – and for the first time found rapidly changing conditions, with temperatures on the hot ‘day’ side of the planet swinging between 1000 and 2700 degrees Celsius.

NASA's Spitzer Spots Planet Deep Within Our Galaxy Feature15-04_sq Spitzer Space Telescope Tue, Apr 14, 2015

NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known.

Our Sun Came Late to the Milky Way's Star-Birth Party Late-sun-sq Spitzer Space Telescope Thu, Apr 09, 2015

Our Sun missed the stellar "baby boom" that erupted in our young Milky Way galaxy 10 billion years ago. During that time the Milky Way was churning out stars 30 times faster than it does today. Our galaxy was ablaze with a firestorm of star birth as its rich reservoir of hydrogen gas compressed under gravity, creating myriad stars. But our Sun was not one of them. It was a late "boomer," arising 5 billion years later, when star birth had plunged to a trickle.

The Solar System and Beyond is Awash in Water Feature15-03_sq Spitzer Space Telescope Tue, Apr 07, 2015

As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways.

Far IR Surveyor Workshop Irpanel Announcement Fri, Mar 27, 2015

NASA is seeking input from the science community that will culminate in a decision to support studies of three or four large missions to prepare for the next Decadal Survey in Astrophysics. A white paper released by NASA's Astrophysics Division lists four candidate missions, including a Far-Infrared Surveyor mission.

Mocking the Universe: Better Science Through Data Simulation Announcement Wed, Feb 18, 2015

In the coming era of LSST, PanSTARRS, WFIRST, Euclid, ALMA, ELTs, JWST, and other facilities, we want to know: What science can we learn by injecting more astrophysics into mock catalogs, and how can we use mock data to maximize the science output of real data? This workshop will cover a variety of astronomy topics bound together by their need to mock the universe.
