Astronomers help find most distant galaxy using James Webb Space Telescope
An international team of astronomers today announced the discovery of the two earliest and most distant galaxies ever seen, dating back to only 300 million years after the Big Bang. These results, using NASA's James Webb Space Telescope (JWST), mark.....»»
Black holes are firing beams of particles, changing targets over time
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested in astronomy.....»»
TESS finds intriguing world sized between Earth and Venus
Using observations by NASA's TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make.....»»
Dyson spheres: Astronomers report potential candidates for alien structures, and evidence against their existence
There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts. Another is to look for evidence of them visiting.....»»

Potentially habitable "exo-Venus" with Earth-like temperature discovered
Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The new paper "Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS.....»»
Stargazing in broad daylight: How a multi-lens telescope is changing astronomy
Astronomers at Macquarie University have pioneered a new technique for observing celestial objects during the day, potentially allowing around-the-clock visual monitoring of satellites and greatly improving safety on Earth and in space......»»
Astronomers observe jet reorientation in "Death Star" black holes
Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA's Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astrono.....»»
Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting......»»
