Asteroid Bennu is old before its time thanks to the sun The bumpy, irregular surface of an asteroid can be seen covered in craters and rocks. A mosaic image of the asteroid Bennu created by observations made by NASA's OSIRIS-REx spacecraft.

'Neutrino factories' could hold the solution to the cosmic ray mystery New research has revealed that high-energy neutrinos and cosmic rays that bombard the Earth from deep space originate in blazars — actively galactic nuclei (AGN) that lurk at the center of galaxies and are powered by supermassive black holes.

The heaviest neutron star ever observed is shredding its companion Most pulsars spin rather slowly, about once per second. PSR J0952-0607, on the other hand, completes over 700 rotations every second, which makes it one of the fastest spinning neutron stars known (in addition to being the heaviest).

The first telescope of its kind will hunt for sources of gravitational waves Scientists liken the gravitational wave detections to sensing the vibrations of a road's surface when a truck has passed, but not being able to actually see the truck. It's almost impossible to know where to look with optical telescopes to search for the ...

Explosive volcanism on Mars deposited rare mineral into Gale Crater, NASA rover finds A team of planetary scientists from Rice University, NASA's Johnson Space Center, and the California Institute of Technology (CalTech) believe that the concentrated chunk of tridymite was spewed into the Gale Crater by a volcano when it was still filled ...

New Instrument Could Spy Signs of Alien Life in Glowing Rocks Was Mars ever a living world? Billions of years ago, before it became a freeze-dried desert, the Red Planet was much more Earth-like, with liquid water and clement temperatures at its surface. Perhaps it harbored life, too. But most signs of any ...

Gorgeous Hubble Space Telescope image shows turquoise waves rippling through Milky Way companion The photo, taken by Hubble in 2014, captures bright, glowing plumes of gas and glittering stars. The turquoise plumes and nebulous strands of the Tarantula Nebula appear to flood the LMC like ocean currents cascading into space.

Heaviest neutron star to date is a 'black widow' eating its mate A dense, collapsed star spinning 707 times per second—making it one of the fastest spinning neutron stars in the Milky Way galaxy—has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into the heaviest ...

The James Webb Space Telescope is on the hunt for the universe's 1st-ever supermassive black holes (The black hole is also called an active galactic nucleus for its position at the heart of galaxy NGC 7319.) The stunning image that NASA released combines snapshots taken by both the Near Infrared ...
