The Hubble Space Telescope (HST) upended beliefs about the fundamental nature of the Universe, delivering evidence that the Universe was not slowing down, as gravity seemingly implied it must be, but expanding. 25 years later, the James Webb Space Telescope (JWST) can help scientists make another breakthrough.
New Juno Images Show Volcanic Activity on Jupiter’s Moon, Io
Over the weekend, NASA's Juno spacecraft made another close flyby of Jupiter's moon, Io. Like a prior flyby last December, the encounter is designed to help scientists understand the volcanic nature of the moon, the most volcanic in the entire solar system.
Hubble’s New Photo Shows the Immense Scale of Galaxies
The Hubble Space Telescope's new Picture of the Week shows a remarkably dense field of stars. However, what at first glance looks like just a field of stars, spread somewhat irregularly through the frame, the photo shows a considerable portion of a galaxy.
A Galactic Interaction Smushed This Spiral Galaxy
The spiral galaxy UGC 3912 doesn't look like much of a spiral in a new image captured by the Hubble Space Telescope. Its unusual and distorted shape is due to a gravitational encounter with a separate galaxy.
