Astronomers have a new name for these sorts of flares from supermassive black holes in distant galaxies: they’re calling them quasi-periodic eruptions. “Giant black holes regularly flicker like a candle but the rapid, repeating changes seen in GSN 069 from December onwards are something completely new,” said one scientist.
The forecast for the planet known as K2-18b is rain. With a chance of life. And although it’s a slim chance, a newly published international study suggests the planet is literally drenched in potential. Not only did researchers detect water…
Scientists Detect Tone Pattern in the Ringing of a Newborn Black Hole for the First Time, Proving Einstein Right Again
100 years after Einstein predicted the existence of gravitational waves, scientists have confirmed that he was right about black holesâagain.
It’s a huge bipolar structure, centered on the galactic center and near the central supermassive black hole. In that way, it’s like the Fermi Bubbles, found some years ago. But … there are differences.
Whoa! It’s a first-ever detection of water vapor in the atmosphere of a potentially habitable super-Earth, located 110 light-years away. The discovery supports the possibility that our galaxy contains many such habitable worlds.
The lakes on Saturn’s moon Titan are filled with liquid methane, not water, and some are surrounded by steep rims. A new study suggests these features might have been caused by explosions of warming nitrogen, which created Titan’s lake basins long ago.
Chinese media have reported that the Yutu-2 rover has discovered a “gel-like” substance in a crater on the far side of the moon. It sounds intriguing, but details are still scarce.
