Mysterious ‘ghostly’ shadows larger than planet Earth reappeared on Saturn’s rings....
NASA's Hubble telescope observed the latest series of mysterious dark spots on Saturn's rings.Scientists have observed these "spokes" for decades but don't know their origin or cause.NASA said Saturn is approaching a key point in its orbit that may make them more common.

An exoplanet is getting vaporized but is trying to hide it
Enlarge / Artist's conception of the atmosphere being blasted off an exoplanet. Some planets cannot hold on to their atmospheres. It's thought that most of whatever atmosphere Mars may have had was annihilated by the solar wind billions of years ago, even as Earth and Venus held on to theirs. But there are planets that…
Even Hubble’s seeing a growing number of satellite tracks
A combination of space junk and a growing constellation of functional satellites like SpaceX's Starlink have astronomers worried about the potential for orbital materials to interfere with observations. And justifiably so, given that researchers are currently arguing over whether one observation represents one of the farthest supernovae ever observed or a spent Russian booster. This…
Hubble Spots Stealthy Asteroid Photobombing a Fuzzy Galaxy ...
A Hubble Space Telescope image released Monday has an obvious target in the middle: hazy galaxy UGC 7983. But as with many Hubble images, there's a lot more going on here than initially meets the eye. Can you also spot the photobombing asteroid?UGC 7983 is a small galaxy located 30 million light-years away in Virgo. The…
Scientists may have found the first water worlds
NASA, ESA, Leah Hustak Two planets that were originally discovered by the Kepler mission may not be what we thought they were. Based on an initial characterization, it was thought these planets were rocky bodies a bit larger than Earth. But continued observation has produced data that indicates the planets are much less dense than…
Single Hubble image captured supernova at three different times
Enlarge / On the left, the full Hubble image. On the right, different images of the gravitationally lensed object.NASA, ESA, STScI, Wenlei Chen, Patrick Kelly Over the last few decades, we've gotten much better at observing supernovae as they're happening. Orbiting telescopes can now pick up the high-energy photons emitted and figure out their source,…
NASA Hubble Sees Spectacular Supernova From 11 Billion Years Ago ...
A supernova is a spectacular example of a star going out with a bang and not a whimper. The Hubble Space Telescope captured an unprecedented view of a supernova's explosive death process from 11 billion years ago. That places the event deep into the past of our 13.8-billion-year-old universe. "This is the first detailed look at…
Hubble Space Telescope Peeks Into Mysterious ‘Keyhole’ in Space ...
I love a good space mystery. A dark "keyhole" splotch in the midst of nebula NGC 1999 in the Orion constellation has turned out to be a science head scratcher. The Hubble Space Telescope captured an ethereal view of the nebula, a huge cloud of dust and gas created by the formation of a star. NASA…

Post-impact images of DART mission have not disappointed
Enlarge / Nailed the landing. At a press conference shortly before NASA's Double Asteroid Redirection Test (DART) spacecraft smashed into an asteroid, a reporter tried to get a sense of just what would happen as a bunch of metal and electronics smashed into a pile of rubble left over from the birth of the Solar…
