Weiss Astronomers have observed a supermassive black hole consume a star in two phases and have predicted when it might take a third. If it happens, it could create a fascinating cosmic...
Artist’s impression of an inhabited exoplanet. (NASA/Jay Freidlander) Given the Milky Way's age and size, we would expect to find intelligent civilizations scattered throughout. But where are they? A recent study suggests these civilizations might be so advanced that we simply can't detect them. Reevaluating the Detection of Extraterrestrial Life If extraterrestrials were observing Earth, they might...
The Finder TW2 can capture the cosmos in 48-megapixel photos or 4K video, with AI onboard to help keep things sharpBeaverlab Stargazing can be both complex and costly, but Beaverlab aims to simplify and reduce the expense with the Finder TW2, a user-friendly telescope that claims to be the world’s first AI-powered planetary camera. Beaverlab, known...
An artist's impression of ASKAP with the two most likely candidates for the repeating radio signal it's foundCarl Knox/OzGrav Astronomers Detect Unusual Hourly Radio Signal from Space Astronomers have detected a highly unusual radio signal from space that repeats every hour, cycling through three distinct states. Despite some hypotheses about its origin, it remains unexplained by...
Credit: Pixabay In a thrilling advancement for astronomy and the quest for extraterrestrial life, an international team of scientists has revealed the discovery of Gliese 12 b, a temperate, Earth-sized exoplanet located just 40 light-years away, which equates to a relatively close 378 trillion kilometers from Earth. Researchers globally, with significant contributions from McGill University and...
Saturn has a minimum of 146 moons, making it the planet with the most moons in the solar system.

By scanning the night sky for the constellation Corona Borealis, you might catch a glimpse of what appears to be a new star. "This brightening point of light is not actually a new star but a nova eruption occurring...
A supermassive black hole in galaxy SDSS1335+0728 has lit up, possibly giving astronomers a look at how such beasts are awakened.M. KORNMESSER/ESO For the last four years, astronomers have observed the supermassive black hole at the center of SDSS1335+0728 undergo a transformation from a dim and inactive state to a bright and active one. This...
Located 1,232 light-years away, WASP-193b is an exoplanet nearly 50 percent larger than Jupiter. Surprisingly, its density is comparable to that of cotton candy, being just over 1 percent of Earth's density. Described as an "absolute dandelion puff-ball of a world," it's one of the most peculiar discoveries in the galaxy.
