Hubble Space Telescope

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.

Amid the Soul Nebula's harsh red light, a cocoon of gas holds baby stars in the making in this ethereal new Hubble telescope image.

China's Xuntian space telescope is scheduled to launch in 2024 and was designed to outdo NASA's Hubble.

Hubble's image of two colliding galaxies, known as Arp 142, show how a small galaxy's gravity has shredded a once-large spiral into a birdlike figure.
