Once upon a time, in a galaxy far, far away, a black hole swallowed a neutron star. Then, 10 days later, another black hole ate up another star. The two separate events triggered ripples through time and space that eventually hit Earth. Those ripples, first detected in January 2020, offered […]

In January last year, astronomers definitively observed, for the first time, a black hole swallowing a dead star, like a raven devouring roadkill. Then 10 days later, they saw the same act of scavenging happen again in a different, distant sector of the cosmos. Those triumphs, reported in a paper […]
By Leah Crane A black hole consumes a neutron star Deborah Ferguson (UT Austin), Bhavesh Khamesra (Georgia Tech), and Karan Jani (Vanderbilt) Astronomers have definitively detected a black hole devouring a neutron star for the first – and second – time. These cataclysmic events created ripples in space-time called gravitational […]
Scientists have detected two collisions between a neutron star and a black hole in the space of 10 days. Researchers predicted that such collisions would occur, but did not know how often. The observations could mean that some ideas of how stars and galaxies form may need to be revised. […]

This artist’s conception of quasar J0313-1806 depicts it as it was 670 million years after the Big Bang. Quasars are highly energetic objects at the centers of galaxies, powered by black holes and brighter than entire galaxies. Shown here is a phenomenon known as zodiacal light, which is caused by […]
WASHINGTON — NASA has selected four small astrophysics missions for further study, although the agency cautions that not all may ultimately be flown. NASA announced Jan. 7 it selected three smallsat missions and one high-altitude balloon mission as the first in its new Astrophysics Pioneers program. The program, established last […]
