Contradicting long-standing theories, a recent study has found that x-ray emissions from black hole jets vary over short periods, and occur throughout the jets rather…
The unexpectedly lonely galaxy 3C 297, discovered 9.2 billion light-years from Earth, has challenged existing theories on galaxy formation. Researchers suggest it may be the…
Chandra X-ray Observatory Helps Astronomers Discover a Surprisingly Lonely Galaxy There is a surprisingly lonely galaxy about 9.2 billion light-years from Earth. Its surroundings have…
New research reveals that supernovae can pose an additional, previously unidentified threat to nearby planets. This involves intense X-rays, generated when a supernova’s blast wave…
A Texas Tech astronomer is leading a team awarded a highly competitive Chandra program to study the stellar remnants in the Large Magellanic Cloud. Vallia…
Researchers using NASA’s Chandra X-ray Observatory have studied the powerful winds in the center of the spiral galaxy NGC 253, which play a crucial role…
Astronomers have determined supernova explosions pose yet another threat to planets and their atmospheres. This result comes from analysis of X-ray observations for over 30…
Astronomers discovered the first evidence of giant black holes in colliding dwarf galaxies, offering important insights into early universe galaxy formation and black hole growth….
NASA’s Chandra X-ray Observatory helped identify two pairs of dwarf galaxies on track to merge. Dwarf galaxies, which are at least about 20 times less…
About 10,000 years ago, light from the explosion of a giant star in the constellation Vela arrived at Earth. This supernova left behind a dense…
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…
