NASA’s Chandra X-ray Observatory studies Cosmic Cold Front in Perseus Galaxy

 

NASA Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – This winter has brought many intense and powerful storms, with cold fronts sweeping across much of the United States. On a much grander scale, astronomers have discovered enormous “weather systems” that are millions of light years in extent and older than the Solar System.

The researchers used NASA’s Chandra X-ray Observatory to study a cold front located in the Perseus galaxy cluster that extends for about two million light years, or about 10 billion billion miles.

Galaxy clusters are the largest and most massive objects in the Universe that are held together by gravity. In between the hundreds or even thousands of galaxies in a cluster, there are vast reservoirs of super-heated gas that glow brightly in X-ray light.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Deep Space Network Helps With ‘Optical Navigation’

NASA’s New Horizons spacecraft recently began its long-awaited, historic encounter with Pluto. The spacecraft is entering the first of several approach phases that culminate July 14th with the first close-up flyby of the dwarf planet, 4.67 billion miles (7.5 billion kilometers) from Earth.

“NASA’s first mission to distant Pluto will also be humankind’s first close up view of this cold, unexplored world in our solar system,” said Jim Green, director of NASA’s Planetary Science Division at the agency’s headquarters in Washington. “The New Horizons team worked very hard to prepare for this first phase, and they did it flawlessly.”

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, dwarf planet Ceres.

“This is the first time water vapor has been unequivocally detected on Ceres or any other object in the asteroid belt and provides proof that Ceres has an icy surface and an atmosphere,” said Michael Küppers of ESA in Spain, lead author of a paper in the journal Nature.
