Gullies on Mars may have formed when the Red Planet was highly tilted on its side, triggering dramatic shifts in climate that sent water cascading down slopes to carve out ravines.
Data from the closest cosmic supernova explosion to Earth for 10 years was collected by a record number of observers for SETI, showing what the collective power of citizen scientists can achieve.
A dazzling new photo from the Hubble Space Telescope shows a distant galaxy that hosted a supernova explosion not long ago.
The velocity of interstellar objects passing through our solar system, like 'Oumuamua, can be correlated to their chemistry and the type of star they came from.
The James Webb Space Telescope spotted three objects that may be 'dark stars,' or stars that are powered by dark matter. But follow-up work is needed to learn their nature.
Astronomers have discovered an ultracold brown dwarf, a "failed star" smaller than Jupiter and colder than a campfire that is emitting radio waves.
India's third lunar exploration mission, Chandrayaan-3, launched on July 14. The mission's lander and rover are scheduled to touch down on the moon in late August.
