Clever camerawork allowed scientists to view an elusive cloud that streams away from Mars' volcano Arsia Mons and determine how it's formed.

A new study reveals a distant exoplanet with one hemisphere pulsing with volcanic activity and the other hemisphere quietly providing the fuel.

The zodiacal light is a strange pyramid of light that extends from the eastern or western horizon, before dawn or as true darkness falls. It was known to stem from dust moving in the plane of our solar system. The Juno spacecraft has found that Mars might be the source of the dust.

UK scientists and meteor experts have recovered pieces of a rare meteorite, just days after it entered Earth's atmosphere and streaked across the sky. Researchers are ecstatic. "Normally we have to send spacecraft to collect bits of other worlds, but this time one has fallen right into our laps!" one said.

Remember in late 2019, when the famous red star Betelgeuse suddenly and mysteriously began dimming in brightness? Astronomers studying a similar star - VY Canis Majoris, one of the largest and brightest stars in our galaxy - commented that it's "... behaving a lot like Betelgeuse on steroids."

Most exoplanets orbiting close to their stars don't have atmospheres. But Gliese 486b - orbiting a red dwarf star only 24 light-years away - does. It's close enough to see well. Astronomers will be watching it!

On Friday, March 5, two astronauts will perform the 2nd in a pair of International Space Station spacewalks to ready the station for solar array upgrades. How to watch live.

NASA has selected 16 cool new futuristic space technology concepts for further study. Four of them are from NASA's own Jet Propulsion Laboratory (JPL), including a railway system on the moon to move cargo.

The striped pattern on the parachute used by the Perseverance rover to land on Mars contained a hidden message. Internet sleuths were able to figure it out within a few hours.

Astronomers found a high energy neutrino - a cosmic ray - that apparently originated during a "tidal disruption event," that is, when a supermassive black hole shredded a distant star.
