NASA’s NICER instrument discovers Black Hole consuming nearby Star

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Scientists have charted the environment surrounding a stellar-mass black hole that is 10 times the mass of the Sun using NASA’s Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station.

NICER detected X-ray light from the recently discovered black hole, called MAXI J1820+070 (J1820 for short), as it consumed material from a companion star. Waves of X-rays formed “light echoes” that reflected off the swirling gas near the black hole and revealed changes in the environment’s size and shape.

In this illustration of a newly discovered black hole named MAXI J1820+070, a black hole pulls material off a neighboring star and into an accretion disk. Above the disk is a region of subatomic particles called the corona. (Aurore Simonnet and NASA’s Goddard Space Flight Center)

NASA to study Neutron stars for groundbreaking Space Navigation Technology

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Neutron stars have been called the zombies of the cosmos. They shine even though they’re technically dead, occasionally feeding on neighboring stars if they venture too close.

Interestingly, these unusual objects, born when a massive star extinguishes its fuel and collapses under its own gravity, also may help future space travelers navigate to Mars and other distant destinations.
