A daily update by email. Science news, great photos, sky alerts.
NASA's Hubble Space Telescope has sent back new images of Jupiter's stormy weather. Hubble monitors the atmospheres of all the giant planets every year.
The recently redesigned Space Telescope Live webapp gives up-to-the-minute information about what the Hubble and Webb space telescopes are observing.
NASA's Hubble telescope has recently observed spoke season in Saturn's rings. The spokes are ghostly transient features that appear and disappear seasonally.
In 2018, the International Astronomical Union voted to rename Hubble's law as the Hubble–Lemaître law to share credit between Edwin Hubble and Georges Lemaître.
The giant planet Jupiter reached opposition this week, coming closest to Earth for the year. In celebration, NASA released this ultraviolet view of Jupiter.
Scientists using the Hubble space telescope have found evidence for an intermediate-mass black hole in the closest globular cluster to Earth, M4.
The Hubble Space Telescope keeps an eye on the planets in space, watching the weather and seasons change on planets such as Jupiter and Uranus.
NASA has released a new Hubble movie of the DART asteroid impact from September 26, 2022. The sequence of images shows the impact and resulting spray of debris.
A new study shows satellites are photobombing Hubble more and more often, ruining observations and negatively impacting science.
Enjoy the new video of some of Hubble's greatest hits. The video, titled Cosmic Wonders, takes you on a 3D journey through nebulae and galaxies.
The Hubble Space Telescope is slowly sinking lower in orbit. Now NASA, SpaceX and the Polaris Program have announced they plan to study how to boost it.
Webb and Hubble images of M74 - the Phantom Galaxy - show how the 2 telescopes "see" differently because they observe at different wavelengths.
For the first time, astronomers have discovered a lone black hole, moving like a ghost or phantom among the stars of our Milky Way galaxy.
When astronomers realized that asteroids photobombed deep space images from Hubble, citizen scientists got to work. The result: over 1,000 new asteroid discoveries!
Astronomers using the Hubble Space Telescope have, for the 1st time, observed a giant new planet forming around another star via disk instability.
Astronomers have found the most distant star yet, thanks to rare alignment with a lensing galaxy cluster. They've nicknamed the star Earendel.
NASA has released stunning new images of Jupiter, Saturn, Uranus and Neptune from the Hubble Space Telescope. These annual observations are called Hubble's Grand Tour of the outer solar system.
NASA's rebooted Hubble Space Telescope was used successfully to capture images of oddball galaxies, following a return to normal science operations.
The Hubble Space Telescope is now back online after having been in a protective safe mode due to a degrading computer memory module since June 13, 2021.
New images of the oldest known pairs of quasars, farthest and oldest yet seen, show that their home galaxies are colliding.
