Astronomers using NASA’s Chandra X-ray Observatory have spotted a bubble of ultrahot gas at the center of a planetary nebula called IC 4593.
This composite...
Mars was once a wet planet, but it has lost most of its water through reactions that produce hydrogen. In standard models, molecular hydrogen produced...
Several billion years ago, a short gamma-ray burst unleashed more energy in a half-second than our Sun will produce over its entire 10-billion-year lifetime....
A team of scientists from Lamont-Doherty Earth Observatory at Columbia University has discovered paleolake basin situated beneath the ice sheet in northwest...
Europa, the sixth of Jupiter’s moons and the fourth largest, has a subsurface ocean covered by an icy shell. Despite evidence for plumes on the icy moon,...
Astronomers using the Low-Frequency Array (LOFAR) radio telescope have discovered a new brown dwarf, a substellar object not quite massive enough to fuse...
SDSS J0901+1814, a giant galaxy cluster located 3.9 billion light-years away in the constellation of Cancer, is so massive that its gravity distorts and...
Using the spectral data collected by the Visual and Infrared Mapping Spectrometer (VIMS) onboard NASA’s Cassini spacecraft, a team of researchers has...
On October 27, 2020, at 4:40 EDT (1:40 p.m. PDT), NASA’s Mars 2020 spacecraft, which includes the Perseverance rover and the Ingenuity helicopter, reached...
Two massive lenticular galaxies, NGC 2292 and NGC 2293, approached one another too closely in the distant past, gravity causing them to affect each other...
Barnard’s star, a 10-billion-year-old red dwarf just 6 light-years from Earth, is still very active and potentially destructive for the atmospheres of...
The NASA/ESA Hubble Space Telescope has produced an outstanding image of a spiral galaxy called UGCA 193.
This Hubble image shows the edge-on spiral galaxy...
On October 28, 2020, NASA’s OSIRIS-REx spacecraft successfully stowed its Sample Return Capsule (SRC) with a sample of surface material from the near-Earth...
NASA’s Juno spacecraft has been in orbit around Jupiter since 2016. One of its instruments is the ultraviolet spectrograph (UVS), which is primarily...
