The specks of planet-forming material are emerging around HOPS-315, a protostar or baby star located 1,300 light-years away from us. One light year is approximately 5.88 trillion miles.

Located nearly 20,000 light-years from Earth, this red supergiant boasts a staggering volume 10 billion times greater than our Sun.Part of the Stephenson star cluster, Stephenson 2-18 is so ...

It orbits extremely close to its star, only about 1/5th as far away as Mercury is from the sun. New research shows that this planet is young, only about 8 million years old.

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new simulations show.

Could a passing star be on a collision course with our solar system and, eventually, Earth? It’s difficult to know if such an outcome is likely. Recently, researchers have found the Milky Way ...

This is enough energy, it turns out, to power a star. If you like mind-boggling numbers, the sun produces 4 x 10 26 watts of power—400 trillion trillion watts.

Kaib previously published work that suggested Earth's orbit was altered by a passing star three million years ago. “We looked at the typical, run-of-the-mill flybys,” Raymond told New Scientist.
