Was Mercury formed by a cosmic hit-and-run?
The early years of our solar system were a period of unimaginable chaos and violence, a gravitational free-for-all where colliding planetary embryos competed for survival. In this tumultuous ...
Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, ...
What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how you look at it. The James Webb Space Telescope has helped two international ...
