Cataclysmic variable V1425 Aql has an arc-shaped nova shell, observations find
Using the Very Large Telescope (VLT), Chilean astronomers have observed a cataclysmic variable known as V1425 Aql. As a result, they have found that this system hosts an arc-shaped nova shell. The finding is presented in ...
Super-Earth discovery reveals an exoplanet potentially capable of sustaining life
Thirty years after the discovery of the first exoplanet, astronomers have detected more than 7,000 of them in our galaxy. But there are still billions more to be discovered. At the same time, exoplanetologists have begun ...

Astronomers discover new lensed, dual and projected quasars
Chinese astronomers have investigated quasar candidates from the DESI Legacy Surveys (DESI-LS) photometry catalog. As a result, they detected 19 strongly-lensed, dual and projected quasars. The finding was reported in a paper ...
Dwarf planet Ceres may have received organic material from space objects
The organic material found in a few areas on the surface of dwarf planet Ceres is probably of exogenic origin. Impacting asteroids from the outer asteroid belt may have brought it with them.

Ingenuity measurements reveal surprising wind speeds on Mars
One of my gripes with "The Martian" movie was the depiction of the winds on Mars. The lower air density means that the sort of high speed winds we might experience on Earth carry far less of an impact on Mars. During its ...
