An arc that glows green thanks to doubly ionized oxygen appears near the Andromeda Galaxy in a photo obtained by amateur astronomers.
Astronomers have discovered that one of the Milky Way’s nearest galactic neighbors has dramatically changed its looks in the recent past.
The James Webb Space Telescope has confirmed its first exoplanet, a rocky Earth-size planet, and attempted to take the measure of its atmosphere.
