New research looks at neutron star blasts

X-ray bursts are highly energetic releases of radiation from the surfaces of neutron stars, triggered by the explosive burning of material accumulated on the surface. It's the same type of burning that happens in the cores ...

NICER catches record-setting X-ray burst

NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station detected a sudden spike of X-rays at about 10:04 p.m. EDT on Aug. 20. The burst was caused by a massive thermonuclear ...

Spiral arms in a young accretion disk around a baby star

An international research team, led by Chin-Fei Lee at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has detected a pair of spiral arms in an accretion disk around a protostar (baby star), using ...

Going against the flow around a supermassive black hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this ...

NASA visualization shows a black hole's warped world

This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole where infalling matter ...

Space dragons: Researchers observe energy consumption in quasars

Quasars are the universe's brightest beacons; shining with magnitudes more luminosity than entire galaxies and the stars they contain. In the center of this light, at the heart of a quasar, researchers think, is an all-consuming ...
