For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the…
Colorful swirling clouds in Jupiter’s North Equatorial Belt practically fill this image from NASA’s Juno spacecraft. This is the closest image captured of the Jovian…
Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its…
This stunning spiral galaxy is Messier 100 in the constellation Coma Berenices, captured here by the NASA/ESA Hubble Space Telescope — not for the first…
Every few hours observing the Moon, ESA’s ‘NELIOTA’ project discovers a brilliant flash of light across its surface – the result of an object hurtling…
The SPECULOOS Southern Observatory (SSO) has been successfully installed at the Paranal Observatory and has obtained its first engineering and calibration images — a process…
Astronomers have detected a bright X-ray outburst from a star in the Small Magellanic Cloud, a nearby galaxy almost 200,000 light years from Earth. A…
Astronomers have discovered a distant planet with an abundance of helium in its atmosphere, which has swollen to resemble an inflated balloon. An international team…
The first unbiased survey of protoplanetary disks surrounding young stars in the Taurus star-forming region turned up a higher-than-expected number of disks with features suggesting…
Researchers from the University of Portsmouth have made vital contributions to the observations of four new gravitational waves, which were announced this weekend. The new…
Most stars with the mass of the sun or larger have one or more companion stars, but when and how these multiple stars form is…
After traveling through space for more than two years and over two billion kilometers, NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived…
This series of images from NASA’s Juno spacecraft captures changing cloud formations across Jupiter’s southern hemisphere. A cloud in the shape of a dolphin appears…
