Hubble Space Telescope

The sparkling galaxy NGC 1546 stars in Hubble's first new image since changing to its new "one-gyro mode," ending the telescope's roughly month-long break.

The Hubble Space Telescope's stunning image of the dusty 'train-wreck' galaxy NGC 4753 reveals what may be one of the greatest optical illusions in the nearby universe.

Astronomers celebrated the Hubble Space Telescope's 34th anniversary with this stunning image of the Little Dumbbell Nebula — a vast cloud of gas containing one of the hottest white dwarf stars ever found.

Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.

ESO 420-G013 is a face-on spiral galaxy with an almost perfectly round disk and an active black hole lighting up its starry guts.

The irregular dwarf galaxy UGC 8091 is likely a building block of ‘grand design’ galaxies like our Milky Way.

University of Chicago astronomer Wendy Freedman tells us how she's searching for an answer to the Hubble tension — a discrepancy between measurements of our universe's expansion that could threaten the dominant model of how the universe has grown since the Big Bang.

The Hubble Telescope viewed a distant galaxy whose light appears to contradict some of the most common rules of quantum physics.

NASA's Hubble Space Telescope snaps the dramatic swirling lines of spiral galaxy NGC 1566, also known as the Spanish Dancer Galaxy.

The James Webb and Hubble space telescopes have combined forces to image a cluster of galaxies 4.3 billion light-years away in one of the most colorful pictures of the universe ever taken.
