Setting the Clock on a Supernova – Stellar Explosion Just Hundreds of Years Ago in Earth’s Timeframe
A new image of SNR 0519-69.0 shows the debris of a star that exploded several hundred years ago in Earth’s timeframe. The explosion of a…

Zeta Ophiuchi is a single star that likely once had a companion that was destroyed when it went supernova. The supernova explosion sent Zeta Ophiuchi,…
A pulsar is racing through the debris of an exploded star at a speed of over a million miles per hour. To measure this, researchers…
This is a sonification — translation into sound — of the latest image from the Event Horizon Telescope (EHT) of the supermassive black hole at…
Two new sonifications of well-known black holes have been released for NASA’s Black Hole Week. The Perseus galaxy cluster was made famous because of sound…
In some of the most crowded parts of the universe, black holes may be ripping apart thousands of stars and using their remains to pack…
Astronomers have found evidence for the destruction of thousands of stars in multiple galaxies, using NASA’s Chandra X-ray Observatory. Growing black holes within dense stellar…
To look for black holes around the “Spiderweb” galaxy, astronomers observed for over 8 days with NASA’s Chandra X-ray Observatory. Chandra revealed 14 actively growing…
A city-sized collapsed star has generated a beam of matter and antimatter that stretches for trillions of miles. Data from NASA’s Chandra X-ray Observatory revealed…
NASA’s Chandra X-ray Observatory continues to study GW170817, a neutron star merger that produced gravitational waves. Many telescopes saw different kinds of light after the…
Astronomers have imaged a beam of matter and antimatter that is 40 trillion miles long with NASA’s Chandra X-ray Observatory. The record-breaking beam is powered…
Astronomers may have detected a “sonic boom” from a powerful blast known as a kilonova. This event—called GW170817—is a result of a merger of two…
Strange ‘sonic boom’ accompanied unprecedented event. Mysterious X-rays observed 3.5 years after the merger of two neutron stars Astrophysicists believe a kilonova afterglow or materials…
Results narrow in on what powers new class of supernovae. Another member of the new “Cow” class of supernova explosions has been discovered—the brightest one…
A new gallery of images combining X-ray data from Chandra with those from other telescopes is being released. The objects range from a supernova remnant…
The discovery of a supermassive black hole in a relatively small galaxy could help astronomers unravel the mystery surrounding how the very biggest black holes…
Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA’s Chandra X-ray Observatory. This unusual set of features…
Astronomers have discovered a supermassive black hole in the dwarf galaxy Mrk 462 with NASA’s Chandra X-ray Observatory. The percentage of these galaxies that have…
