Hubble Space Telescope

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.

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.

Arp 107 hosts a special spiraling 'Seyfert' galaxy connected to a smaller galaxy by a 'bridge' of dust and gas.

A team of astronomers has used a tricky technique to study an ancient galaxy previously lost in the glare of a blazing quasar.
