Astronomers used the ALMA telescope in Chile to observe irregular flickers in millimeter-waves from the center of our Milky Way galaxy: the twinkling heart of the galaxy.

We suspect most of you have not seen this comet, which is rising only shortly before the sun now. Let the Virtual Telescope’s Gianluca Masi show it to you online this week.

Scientists studying the ancient Martian Tissint meteorite say they’ve found new evidence that Mars was volcanically active a few hundred million years ago … and may still be today.

Trojan asteroids orbit 60 degrees ahead of and behind Jupiter, in its wide orbit at 5 times Earth’s distance from the sun. Now the 1st Trojan asteroid has been found with a comet-like tail.

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.

Future astronauts on the moon will need to have water, and now NASA has designed a new CubeSat spacecraft to search for ice in lunar craters using laser beams.

Scientists studying the huge, hot exoplanet WASP-79b have found that, surprisingly, the planet has yellow skies instead of blue. But why it does is still a mystery.

Only 1,000 light-years away, the star system can be seen with the unaided eye.
