Hubble's Planetary Portrait Captures New Changes in Jupiter's Great Red Spot

Scientists using NASA's Hubble Space Telescope have produced new global maps of Jupiter, representing nearly back-to-back rotations of the planet on Jan. 19, 2015, that show the movements of the clouds and make it possible to determine the speeds...

Hubble Zooms in on Shrapnel from an Exploded Star

Astronomers are comparing new images of the Veil Nebula, taken by NASA's Hubble Space Telescope in April 2015 with Hubble images taken in 1997, to study how the nebula has expanded since it was photographed over 18 years ago. The supernova that...

Hubble Survey Unlocks Clues to Star Birth in Neighboring Galaxy


In an intensive citizen-science-aided survey of Hubble telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based...
