A mostly student-run project is studying the Andromeda Galaxy, taking repeated before-and-after photos with relatively small telescopes in hopes of detecting any civilizations using powerful lasers to signal their presence.
Researchers analyzing the trajectory and behavior of ‘Oumuamua, an interstellar body passing through Earth’s solar system, have identified four candidate stars where the unusual comet-like body might have originated.
Re-evaluating data collected 20 years ago by NASA’s now retired Mars Global Surveyor, researchers say the martian moon Phobos could have originated in the aftermath of a titanic planetary collision that blasted surface material into space.
Researchers studying the atmosphere of Saturn’s moon Titan using archived data from NASA’s Cassini spacecraft have spotted infrared signatures of what appear to be giant dust storm blowing across the large moon’s surface.
A new study indicates Mars had more than enough sub-surface hydrogen, from the breakdown of water due to radioactive decay, to support a global microbial biosphere that could have persisted for hundreds of millions of years.
Japan’s Hayabusa2 sample return spacecraft successfully deployed two small landers that dropped to the surface of an astroid known as Ryugu and then began hopping about in a major milestone for the ambitious mission.
Astronomers have measured differential rotation in 13 Sun-like stars where equatorial zones rotate faster than higher latitudes, a phenomenon thought to play a major role in the generation of sunspots and magnetic fields.
