Astronomers used the James Webb Space Telescope to study a planet-forming disk around a low-mass star, finding it contains chemical signatures never seen before in such a disk.

Asteroid 2024 YR4 has a 2.3% chance of hitting Earth in the year 2032. But according to new estimates, it may have an even smaller chance of hitting the moon instead.

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.
