A NASA image of the snow-dusted Grand Canyon has created a striking optical illusion, making the vast chasm-more than a mile ...

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous neighbors, possibly after much of the ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

An interstellar comet racing through our solar system released methanol, methane and cyanide, NASA says. Could these life linked molecules hint at how worlds across the cosmos are seeded?

Using archival data from NASA’s NEOWISE mission along with data from other space and ground-based observatories, astronomers identified the clearest observational record yet of a massive star fading ...

Whether you’re chasing galaxies in California or counting meteors in Uruguay, this year’s top dark sky festivals promise awe, community, and unforgettable views.

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, ...

On 2 July, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose brightness varied rapidly during a routine sky survey. Its unusual signal ...

"This strange disorder makes it a unique inside-out system," study lead author Thomas Wilson, physics professor from the University of Warwick, said in a statement. "Rocky planets don't usually form ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...
