Clouds in the greater universe are clumpy areas of greater density than their surroundings. Space telescopes have observed these cosmic clouds in the vicinity of supermassive black holes.

Scientists in Europe have found more yet evidence for water vapor plumes on Jupiter's ocean moon Europa.

Almost every day, the SWAN instrument aboard the sun-watching SOHO spacecraft makes a map of the sky. Anyone with internet access can view the maps and join the search for new comets. To date, 12 comets have been spotted in the SWAN data!

Researchers in Spain have published a new study revealing details of a multi-layered, sandwich-like haze that hangs above the famous hexagon at Saturn's north pole.

For the first time, nitrogen-containing organic molecules have been discovered in a Martian meteorite. The famous meteorite - Allan Hills 84001 - was picked up in Antarctica in 1984. The discovery provides more clues about habitable conditions on early Mars.

The cloud bands on brown dwarf Luhman 16A were found via instruments known as polarimeters. An astronomer said they're like "... an astronomer's polarized sunglasses. But instead of trying to block out that glare, we're trying to measure it."

It’s a spectacular achievement to rendezvous with an asteroid as it’s whizzing around the sun. It's even more amazing to collect a sample. That's what the Hayabusa2 spacecraft did in February 2019. Here's what researchers learned.

Data sonification uses data to result in a sound, so that you can better perceive what the data show. Here are several audio recordings based on data from the Mercury-bound BepiColombo spacecraft's Earth flyby on April 9.

There's no sound in space. But - working with NASA - musicians and scientists turned a Hubble Space Telescope image of a galaxy cluster into music.

Comet C/2019 Y4 (ATLAS) was getting brighter. Then, sadly, the Hubble Space Telescope caught it apparently disintegrating. Now ... surprise. Veteran comet observer Terry Lovejoy reported earlier today that the comet is brightening again!
