NASA's Goddard Space Flight Center 17 Apr 2019, 15:00 UTC How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it — very, very carefully. This is exactly what NASA planetary scientists did, using data from the agency’s former mission to Mercury.
NASA's Goddard Space Flight Center 17 Apr 2019, 12:49 UTC The newly forming stars in the tail are mysterious because processes common in large groups of galaxies should make it difficult for new stars to emerge. Most galaxies live in groups — for example, the Milky Way is a member of the Local Group, which also contains galaxies like Andromeda and the Triangulum spiral. Some galaxies reside in much larger gatherings of hundreds or even thousands of galaxies known as a galaxy cluster. The “jellyfish” galaxy ESO 137-001 is part of a cluster called Abell 3627.
NASA's Chandra X-ray Observatory 16 Apr 2019, 18:22 UTC A neutron star merger without an observed gamma-ray burst has been discovered using NASA's Chandra X-ray Observatory.
Harvard-Smithsonian Center for Astrophysics 16 Apr 2019, 15:26 UTC Scientists in the VERITAS (Very Energetic Radiation Imaging Telescope Array System) Collaboration have published a paper in Nature Astronomy journal detailing the results of their work with the VERITAS array—located at the Center for Astrophysics' Fred Lawrence Whipple Observatory in Amado, Arizona—to measure the smallest apparent size of stars in the night sky known to date.
Kavli Institute for Cosmology, Cambridge 16 Apr 2019, 06:45 UTC Large differences in the ‘fogginess’ of the early universe were caused by islands of cold gas left behind when the universe heated up after the big bang, according to an international team of astronomers.
NASA's Jet Propulsion Laboratory News and Features 15 Apr 2019, 15:04 UTC On its final flyby of Saturn's largest moon in 2017, NASA's Cassini spacecraft gathered radardata revealing that the small liquid lakes in Titan's northern hemisphere are surprisingly deep, perched atop hills and filled with methane.
