American Astronomical Society 29 Jul 2021, 14:30 UTC ALMA data proves that ram pressure stripping doesn’t spell an immediate end for galaxies.
NASA's Jet Propulsion Laboratory News and Features 29 Jul 2021, 14:00 UTC Three studies published in the past month have cast doubt on the premise of subsurface lakes below the Martian south pole.
American Astronomical Society 28 Jul 2021, 01:10 UTC An international team of astrophysicists has discovered the presence of transverse rotation in three dwarf spheroidal galaxies, a very faint type of galaxies and difficult to observe, which are orbiting round the Milky Way; this helps to trace their evolutionary history.
NASA's Goddard Space Flight Center 26 Jul 2021, 15:00 UTC For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas.
NASA's Goddard Space Flight Center 23 Jul 2021, 12:30 UTC The center of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant galaxies
ESO Top News 22 Jul 2021, 12:00 UTC Using the Atacama Large Millimetre/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have unambiguously detected the presence of a disc around a planet outside our Solar System for the first time. The observations will shed new light on how moons and planets form in young stellar systems.
NASA's Jet Propulsion Laboratory News and Features 22 Jul 2021, 07:00 UTC Three papers published today share new details on the crust, mantle, and molten core of the Red Planet.
