If you lived on one of Pluto’s moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA’s Hubble Space Telescope shows that two of Pluto’s moons, Nix and Hydra, wobble unpredictably. “Hubble has provided a new view of Pluto and […]Read more "Hubble finds Pluto’s moons tumbling in absolute chaos"
In an article in Science (“Birth of a comet magnetosphere: A spring of water ions“) an international research group led from the Swedish Institute of Space Physics shows what happens when a magnetosphere forms round a comet. The RPC-ICA instrument onboard the Rosetta spacecraft has been watching the early stages of how a magnetosphere forms […]Read more "Watching the birth of a comet magnetosphere"
Geologists from the University of Cambridge uncover hidden magnetic messages from the early solar system in meteorites measured at BESSY II. The team of scientists led by Dr. Richard Harrison has captured information stored inside tiny magnetic regions in meteorite samples using the PEEM-Beamline at BESSY II. This information captures the dying moments of the […]Read more "Hard disk from space – Hidden magnetic messages in meteorites"
On Jan. 28, 2014, NASA’s Interface Region Imaging Spectrograph, or IRIS, witnessed its strongest solar flare since it launched in the summer of 2013. Solar flares are bursts of x-rays and light that stream out into space, but scientists don’t yet know the fine details of what sets them off. IRIS peers into a layer […]Read more "NASA | IRIS Spots Its Largest Solar Flare"
Image: European Southern Observatory To get an idea of how the early solar system may have formed, scientists often look to asteroids. These relics of rock and dust represent what today’s planets may have been before they differentiated into bodies of core, mantle, and crust. In the 1980s, scientists’ view of the solar system’s asteroids […]Read more "‘Rogue’ asteroids may be the norm"
Using the NSF’s Robert C. Byrd Green Bank Telescope, astronomer D. J. Pisano from West Virginia University has discovered what could be a never-before-seen river of hydrogen flowing through space. ©NRAO NGC 6946 This very faint, very tenuous filament of gas is streaming into the nearby galaxy NGC 6946 and may help explain how certain […]Read more "River of Hydrogen Flowing Through Space"
At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang Nebula is the coldest known object in the Universe – colder, in fact, than the faint afterglow of the Big Bang, which is the natural background temperature of space. The Boomerang Nebula, called the “coldest place in the Universe,” reveals its true […]Read more "ALMA reveals ghostly shape of ‘coldest place in the universe’"
