An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers ...

NASA's infrared telescope SPHEREx captured stunning images of interstellar comet 3I/ATLAS as it exited the solar system.

The Sun would be a far more powerful telescope than any humanity could create in the near future. But to use it, we need to get to 650 AU.

Sending a mission to the solar gravitational lens (SGL) is the most effective way of actually directly imaging a potentially ...

NASA is quietly entertaining one of the most audacious telescope concepts ever proposed: using the Sun itself as a giant lens ...

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?

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

In the nearby Andromeda Galaxy, a massive star bright enough to stand out for years has gone dark. Not in a blaze of glory.

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

Hubble has captured its clearest view yet of the closest pre-planetary nebula, dubbed Egg Nebula, a dying Sun-like star ...

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.
