NASA's Goddard Space Flight Center 15 Apr 2020, 15:00 UTC After the successful completion of its “Checkpoint” rehearsal, NASA’s first asteroid-sampling spacecraft is one step closer to touching down on asteroid Bennu. Yesterday, NASA’s OSIRIS-REx spacecraft performed the first practice run of its sample collection sequence, reaching an approximate altitude of 246 feet (75 meters) over site Nightingale before executing a back-away burn from the asteroid. Nightingale, OSIRIS-REx’s primary sample collection site, is located within a crater in Bennu’s northern hemisphere.

NASA's Goddard Space Flight Center 10 Apr 2020, 11:35 UTC At first glance, the subject of this NASA/ESA Hubble Space Telescope image looks to be a simple spiral galaxy, with two pinwheeling arms emerging from a central bar of stars and material that cuts through the galactic center. In fact, there are rings within these spiral arms, too: spirals within a spiral.

ESA Top News 9 Apr 2020, 10:30 UTC Mercury is a desert world which scientists until recently considered quite uninteresting. NASA’s Mariner and MESSENGER missions, however, revealed that there is much more to the smallest and innermost planet of the Solar System than meets the eye. Despite temperatures on its surface rising up to 450°C, there seems to be water ice on Mercury. The planet also appears to have a way too large inner core for its size and a surprising chemical composition. Here are the top five Mercury mysteries that the European-Japanese BepiColombo mission might solve.
MIT 8 Apr 2020, 17:59 UTC Microscopic minerals excavated from an ancient outcrop of Jack Hills, in Western Australia, have been the subject of intense geological study, as they seem to bear traces of the Earth’s magnetic field reaching as far back as 4.2 billion years ago. That’s almost 1 billion years earlier than when the magnetic field was previously thought to originate, and nearly back to the time when the planet itself was formed.
