Greek mythology has given a name to a great many objects in our solar system. But perhaps one of the least well understood ...

Astronomers have uncovered evidence of a dramatic cosmic crash unfolding around a distant star. While reviewing archived ...

Scientists uncover a new reason for fewer planets around twin stars. Einstein's theory of general relativity shows that close ...

Planets orbiting two suns are rare. Scientists now understand why. Subtle gravitational forces, amplified by Einstein's relativity, destabilize planetary orbits over eons. This leads to planets being ...

Cancer the Crab is a dim constellation, yet it contains one of the most beautiful and easy-to-spot star clusters in our sky: ...

New ALMA and JWST observations reveal why Wolf–Rayet star WR 112 produces tiny dust grains, showing a bimodal grain distribution in its binary system.

When Anastasios Tzanidakis was sifting through some older telescope observations, he stumbled across something that should ...

Astronomers have caught what may be a rare cosmic catastrophe unfolding 11,000 light-years away. A seemingly ordinary sun-like star suddenly began flickering wildly, puzzling scientists until they ...

An oddly-behaving star led two UW astronomers to capture rare evidence of a collision between two planets in a distant solar ...

Overall, Didymos is nearly 200 times more massive than its smaller companion, which explains why shifting the larger asteroid ...

When NASA’s DART spacecraft deliberately crashed into the asteroid moonlet Dimorphos, it did more than change the asteroid’s local orbit — it slightly shifted the path of the entire asteroid pair ...

In September 2022 NASA smashed a spacecraft into an asteroid. Called Dimorphos, the rock is the smaller asteroid in a binary ...
