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 in real time, offering a rare glimpse of the ...

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 dwarf galaxy embedded in a vast stream of ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected hydrogen cyanide (nitrogen-bearing organic molecule commonly seen in comets) as well as unusually high levels of ...

Stellar activity and plasma turbulence could distort narrow radio signals before they leave their home planetary systems, potentially explaining part of the long silence in the search for ...

Using the NIRSpec data, planetary scientists measured the physical properties of the auroral footprints of Jupiter’s two innermost Galilean moons, Io and Europa, including the local temperature and ...
