If a new quasar is more luminous than any other previously observed, the program might reject it and classify it instead as a star not too distant from Earth." This image shows the region of the sky in which the record-b...
in images taken in 1980 by theSchmidt Southern Sky Survey, a telescope in Australia—but at first, they mistakenly identified it as a star. Typically, astronomers find quasars using machine-learning models trained to survey large areas of the sky ...
"This type of objects harbour the most powerful star forming regions known in the universe. The next step will be to study their molecular content," said co-author of the article Susana Iglesias-Groth.
Spica is the 15th brightest star in the sky and the brightest in the Virgo constellation. The star is also known as Alpha Virginis and is situated around 250light-yearsfrom Earth. Spica is not a single star, but a binary system, meaning two stars orbit closely around one another,every fou...
astronomical myth than reality, with the search for physical proof coming up empty. That contrasts with better known Population I stars like the sun, or Population II stars, which include older stars with a low heavy-element content found in the Milky Way bulge and halo, and globular star ...
Even so, we see quite a lot of them in the night sky, because the ones that do exist are so luminous. To mention just three well-known blue stars, there's Regulus, the brightest star in the constellation Leo, Spica, the brightest star in Virgo and Rigel, the brightest in Orion. ...
He was also a fan of pop culture and appeared on TV shows such as Star Trek and The Big Bang Theory. He celebrated his 60th birthday by going up in a hot-air balloon;when he was 65, he took part in a zero-gravity flight to experience weightlessness. He hoped to travel into space ...
McMahon, working with Michael Irwin of the Royal Greenwich Observatory in Cambridge and Cyril Hazard of the University of Pittsburgh, computer-scanned some 25 million celestial objects depicted on photographic plates and found several star-like entities characteristic of distant quasars--glowing brightly...
The brightest galaxies in our universe are fuelled by what their gravity sucks in, not through explosive mergers of star systems as scientists previously argued, researchers said Wednesday. In what may be the most complete explanation yet of how these enormous collections of stars and dust came to...
The hot accretion disk and the jet combine to make the nucleus of the active galaxy shine so bright that it can be seen far across the universe. Related: James Webb Space Telescope sees 1st starlight from ancient quasars in groundbreaking discovery Quasar FAQs Is a quasar just a black hole...
