This sparkling spiral galaxy looks almost stretched across the sky in this new image from the NASA/ESA Hubble Space Telescope.

Black holes aren't stationary in space; in fact, they can be quite active in their movements.

Hubble Space Telescope's iconic images and scientific breakthroughs have redefined our view of the universe.

Galaxies grow large by eating their smaller neighbours, new research reveals.

New results from an ambitious sky survey program, called ALPINE, reveal that rotating disk-shaped galaxies may have existed in large numbers earlier in the universe than previously thought.

Hubble Probes Colorful Galaxy NGC 2906

This image displays a swirling spiral galaxy named NGC 2906.

Unprecedented observations of a nova outburst in 2018 by a trio of satellites, including two NASA missions, have captured the first direct evidence that most of the explosion's visible light arose from shock waves -- abrupt changes of pressure and temperature formed in the explosion debris.

A research team led by physicists at the University of California, Riverside, reports tiny satellite galaxies of the Milky Way can be used to test fundamental properties of "dark matter" -- nonluminous material thought to constitute 85% of matter in the universe.

Cosmic Tempest

Researchers using the Gemini North telescope on Hawai'i's Maunakea have detected the most energetic wind from any quasar ever measured.

Just as the sun has planets and the planets have moons, our galaxy has satellite galaxies, and some of those might have smaller satellite galaxies of their own.

Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as "intermediate-mass," which betrayed its existence by tearing apart a wayward star that passed too close.

Much of the progress in Astronomy has been driven by instrumental developments, from the first telescopes to fiber fed spectrographs.

Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA).

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation Project, will help improve our understanding of the star formation process.

Quasar Tsunamis Rip Across Galaxies

Using the unique capabilities of NASA's Hubble Space Telescope, a team of astronomers has discovered the most energetic outflows ever witnessed in the universe. They emanate from quasars and tear across interstellar space like tsunamis, wreaking havoc on the galaxies in which the quasars live.

Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole.

A New Type Of Pulsating Star Discovered

A star that pulsates on just one side has been discovered in the Milky Way about 1500 light years from Earth.

SOFIA's Infrared View of the Skies

The Stratospheric Observatory for Infrared Astronomy, SOFIA, studies the universe with infrared light.

The barred spiral galaxy NGC 3887, seen here as viewed by the Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope, lies over 60 million light-years away from us in the southern constellation of Crater (the Cup).

ALMA Spots A Metamorphosing Aged Star

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured the very moment when an old star first starts to alter its environment.
