In today’s Universe, most galaxies are held together by orderly rotation. But among the largest, no-longer star-forming systems, many are instead dominated...
A team of astronomers in Japan has detected a thin atmosphere around (612533) 2002 XV93, a trans-Neptunian object about 500 km in diameter — an object...
Astronomers using the NASA/ESA Hubble Space Telescope have captured this vivid image of the spiral galaxy NGC 3137, which is located in the constellation...
A new anniversary image from the NASA/ESA Hubble Space Telescope reveals surprisingly fast evolution in a turbulent stellar nursery called the Trifid Nebula,...
New Webb observations of two exoplanets TRAPPIST-1b and TRAPPIST-1c show blistering days and frozen nights, offering the first detailed climate maps of...
New images from the NASA/ESA/CSA James Webb Space Telescope reveal two young stars surrounded by planet-forming disks, Tau 042021 (left) and Oph 163131...
The newly-discovered star, SDSS J0715-7334, formed in the halo of the Large Magellanic Cloud and migrated to our Milky Way Galaxy billions of years ago,...
The Hubble team has released a beautiful close-up shot of the barred spiral galaxy IC 486.
This Hubble image shows IC 486, a barred spiral galaxy some...
A new analysis of data from NASA’s Parker Solar Probe shows that protons and heavy ions react differently to solar magnetic reconnection events, suggesting...
Using ESO’s Very Large Telescope (VLT) and VLT Interferometer (VLTI) in Chile, astronomers have directly observed two gas giants emerging from the planet-forming...
A new close-up of the Triangulum galaxy, captured with ESO’s Very Large Telescope (VLT), traces the tangled gas and dust that shape how stars are born...
Using a vast catalog of Sun-like stars built by ESA’s Gaia mission, astronomers have found strong evidence that our home star traveled outward with thousands...
An unusual flickering of a young F-type star called Gaia20ehk and an expanding cloud of dust around it suggest that a catastrophic planetary crash unfolded...
Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint...
The newly-identified gas cloud, dubbed G2t, follows nearly the same orbit as two known clouds, suggesting they were all expelled by a pair of massive stars...
New measurements show that the DART impact in 2022 not only shortened the orbit of the moonlet Dimorphos around its parent asteroid, Didymos, but also...
Stellar activity and plasma turbulence could distort narrow radio signals before they leave their home planetary systems, potentially explaining part of...
