Weigh a Quasar's Galaxy With Precision

June 3, 2023 —Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational lensing quasars is expected to multiply with the launch of Euclid this ...

First Detection of Secondary Supermassive Black Hole in a Well-Known Binary System

June 6, 2023 —An international team of astronomers observed the second one of the two supermassive black holes circling each other in an active galaxy OJ ...

Webb Space Telescope Detects Universe's Most Distant Complex Organic Molecules

June 5, 2023 —Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth -- the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James ...

NASA's Webb Space Telescope Peers Behind Bars

June 5, 2023 —A delicate tracery of dust and bright star clusters threads across this image from the James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image -- a composite from two of Webb's ...

NASA's Hubble Hunts for Intermediate-Sized Black Hole Close to Home

May 23, 2023 —Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest ...

隐藏的超大质量黑洞的生命Galaxies on Collision Course

May 11, 2023 —Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are ...

Celestial Monsters at the Origin of Globular Clusters

May 11, 2023 —Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows ...

Astronomers Find No Young Binary Stars Near Milky Way's Black Hole

May 11, 2023 —Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are formed ...

Galactic Bubbles Are More Complex Than Imagined

May 8, 2023 —Astronomers have revealed new evidence about the properties of the giant bubbles of high-energy gas that extend far above and below the Milky Way galaxy's ...

Astronomers Find Distant Gas Clouds With Leftovers of the First Stars

May 3, 2023 —Using ESO's Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds ...
