New Image from James Webb Space Telescope Reveals Astonishing Saturn and Its Rings

Saturn's iconic rings seem to glow eerily in this incredible infrared picture, which also unveils unexpected features in Saturn's atmosphere. This image serves as context for an observing program that will test the telescope's capacity to detect ...

Gravitational Waves from Colossal Black Holes Found Using 'Cosmic Clocks'

You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy. New results are the first evidence of the gravitational wave background -- a sort of soup ...

Life After Death: Astronomers Find a Planet That Shouldn't Exist

明星会膨胀到p的1.5倍lanet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...

Starlight and the First Black Holes: Researchers Detect the Host Galaxies of Quasars in the Early Universe

For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big ...
