Using the MIRI instrument onboard the James Webb Space Telescope, an international team of scientists made the first-ever detection of a mid-IR flare from Sagittarius A*, the supermassive massive black hole at the heart of ...
Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes—those up to billions of times heavier than the sun. The new survey is unique because it was as likely to find massive black holes ...
An international team of astronomers have investigated a large Galactic supernova remnant designated G278.94+1.35. Results of the study, published Dec. 30 on the pre-print server arXiv, shed more light on the properties of ...
Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky Way, known for its long, thin structure, and unusual ...
Looking halfway across the observable universe and expecting to see individual stars is considered a non-starter in astronomy, a bit like raising a pair of binoculars at the moon in hopes of making out individual grains of ...
This NASA/ESA Hubble Space Telescope Picture of the Week features the galaxy LEDA 22057, which is located about 650 million light-years away in the constellation Gemini. Like the subject of a previous Picture of the Week, ...
Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named Zhúlóng, is extremely massive and ...
Scientists have spotted what appear to be two stars whipping around each other near the supermassive black hole at the center of our Milky Way galaxy.
One of the biggest mysteries in science—dark energy—doesn't actually exist, according to researchers looking to solve the riddle of how the universe is expanding.
The star HD 65907 is not what it appears to be. It's a star that looks young, but on closer inspection, it is actually much, much older. What's going on? Research suggests that it is a resurrected star.
