According to Live Scence, the planet’s shadow was first spotted in 2021 in data taken by the European Space Agency’s Gaia ...

Recent flybys of the fiery world refute a leading theory of its inner structure—and reveal how little is understood about ...

There’s now a 50-50 chance this galaxy will crash into ours. Astronomers have long thought that the Milky Way is headed for an inevitable crash with its neighbor, Andromeda.

Why giant planets might form faster than we thought New observations of 30 planet-forming disks reveal how gas and dust behave over time and shape the evolution of exoplanet systems ...

Using the James Webb Space Telescope astronomers have discovered the smallest brown dwarfs ever seen with the potential to form planets and surrounded by mysterious molecules.

Until now, astronomers had spotted quiescent galaxies as far back as 1.2 billion years after the Big Bang — a time known as redshift 5. RUBIES-UDS-QG-z7 breaks that record, appearing at redshift ...

Today, Mercury passes 2° north of Jupiter at 4 P.M. EDT. You can catch them together in the evening twilight, sinking in the west after sunset. But be quick: They are just a few degrees above the ...

Past theories put a collision between the two—resulting in a new elliptical galaxy dubbed Milkomeda—as probable if not inevitable. Some predictions had that happening within 5 billion years ...

Dec. 18, 2024 — Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars.

Elliptical galaxies were not formed by random stars moving together. It's true there can be clumping in n-body gravitational dynamics, and I hadn't thought before of that possibility, ...
