In 1887, American astronomer Lewis Swift discovered a glowing cloud, or nebula, that turned out to be a small galaxy about 2.2 million light years from Earth.

Hidden from our sight, the Westerhout 43 star-forming region is revealed in full glory in this far-infrared image from ESA's Herschel space observatory.

Australian scientists have discovered why heavyweight galaxies living in a dense crowd of galaxies tend to spin more slowly than their lighter neighbours.

Understanding the history of star formation in the Universe is a central theme in modern astronomy.

In June 2016, an international team of 31 astronomers, led by the University of Maryland's Eleanora Troja and including Arizona State University's Nathaniel Butler, caught a massive star as it died in a titanic explosion deep in space.

Chandra Samples Galactic Goulash

What would happen if you took two galaxies and mixed them together over millions of years? A new image including data from NASA's Chandra X-ray Observatory reveals the cosmic culinary outcome.

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have found new evidence suggesting that a jet of fast-moving material ejected from one young star may have triggered the formation of another, younger protostar.

For decades, scientists thought that the magnetic field lines coursing around newly forming stars were both powerful and unyielding, working like jail bars to corral star-forming material.

Stars form from gas and dust floating in interstellar space. But, astronomers do not yet fully understand how it is possible to form the massive stars seen in space.

The Balloon Experimental Twin Telescope for Infrared Interferometry (BETTII) payload, an astronomy experiment, launched from NASA's Columbia Scientific Balloon Facility (CSBF) in Palestine, Texas, Thursday, June 8, flying through the evening.

In space, being outshone is an occupational hazard.

Hubble Sees Starbursts in Virgo

Although galaxy formation and evolution are still far from being fully understood, the conditions we see within certain galaxies -- such as so-called starburst galaxies -- can tell us a lot about how they have evolved over time.

New Study Maps Space Dust in 3-D

Berkeley Lab-led research raises new questions about properties of dust in local and distant reaches of Milky Way

As British royal families fought the War of the Roses in the 1400s for control of England's throne, a grouping of stars was waging its own contentious skirmish -- a star wars far away in the Orion Nebula.

Hubble Hones in on a Hypergiant's Home

This beautiful Hubble image reveals a young super star cluster known as Westerlund 1, only 15,000 light-years away in our Milky Way neighborhood, yet home to one of the largest stars ever discovered.

Galaxies have dramatically grown in size since the early Universe, and elliptical galaxies, in particular, are the largest galaxies in both size and mass. What is the main driver behind the late growth of their outer parts was the question that motivated this study.

Incredibly rapid gas flares from a white dwarf binary star system have been detected for the first time by Oxford University scientists.

Classifying NGC 4861 In Canes Venatici

The lesser-known constellation of Canes Venatici (The Hunting Dogs), is home to a variety of deep-sky objects -- including this beautiful galaxy, known as NGC 4861. Astronomers are still debating on how to classify it.

Astronomers have discovered a cosmic one-two punch unlike any ever seen before. Two of the most powerful phenomena in the Universe, a supermassive black hole, and the collision of giant galaxy clusters, have combined to create a stupendous cosmic particle accelerator.

Two stars are predicted to merge and explode in 2022 producing a bright star visible to the unaided eye.
