Stars and planets are inextricably linked. They form together and stars shape the fate of planets. Stars create the dusty protoplanetary disks that give birth to planets of all kinds. And when a star ...

There's an iconic scene in the original Star Wars where Mark Hamill's Luke Skywalker watches a double sunset above Tatooine, ...

Astronomers used the James Webb Space Telescope to probe the object, gathering clues on whether it grew larger over time like a planet or fragmented into smaller bits like a star. Stars are born from ...

Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying ...

Far beyond the reach of any spacecraft, a distant world glows with heat so intense that rock itself turns to vapor. In that extreme environment, scientists have uncovered a rare clue about how planets ...

The findings could more than double our current database of worlds that loop around binary star systems. But researchers need ...

Binary star systems may help giant planets form more easily by triggering planet formation far from their stars.

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously ...

Many astronomical objects play by clear rules and fit into neat categories, but brown dwarfs (celestial objects too massive to be mere planets, but too small to be real stars) continue to refuse to ...

This image from a simulation of atmospheric flow shows temperature patterns on one of the newly discovered planets (61Virb), which is hot enough that it glows with its own thermal emission. A movie of ...

Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are ...
