Astronomers have found the most distant X-ray black hole, challenging our understanding of supermassive black hole formation in the early universe. Astronomers using NASA telescopes…
A key indicator of a growing supermassive black hole – X-ray emission – has been found in an extremely distant galaxy. This galaxy, UHZ1, is…
NASA’s X-ray telescopes have unveiled the magnetic “bones” of a hand-shaped space structure, offering profound insights into the behavior of dead stars and the powerful…
NASA’s Chandra and IXPE telescopes unveil the magnetic “bones” of the “hand”-shaped pulsar wind nebula, MSH 15-52, offering groundbreaking insights into X-ray polarization and magnetic…
Astronomers uncover details of a massive star, ASASSN-14li, devoured by a black hole, challenging previous theories and hinting at new methods for cosmic exploration. Researchers…
A giant black hole 290 million light-years away destroyed a large star and threw its pieces into space. NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton…
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,…
