Hubble Observes Barred Spiral Galaxy NGC 2500

Barred Spiral Galaxy NGC 2500

Discovered by British astronomer William Herschel over 200 years ago, NGC 2500 lies about 30 million light-years away in the northern constellation of Lynx.

Chandra Peers Into A Giant Molecular Cloud

Giant molecular clouds are vast cosmic objects, composed primarily of hydrogen molecules and helium atoms, where new stars and planets are born.

Star Forming Galaxies In The Young Universe

Astronomers studying the distant Universe have found that small star-forming galaxies were abundant when the Universe was only 800 million years old, a few percent of its present age.

Heart of an Exploded Star Observed in 3-D

Supernovas -- the violent endings of the brief yet brilliant lives of massive stars -- are among the most cataclysmic events in the cosmos.

Cosmic Dust Factory Provides Clues About Star Birth

A group of scientists led by researchers at Cardiff University have discovered a rich inventory of molecules at the centre of an exploded star for the very first time.

Hubble Pushed Beyond Limits to Spot Clumps of New Stars in Distant Galaxy

IC 342: Hubble's Hidden Galaxy

IC 342 is a challenging cosmic target.

Flow of Material Observed Around a Young Eruptive Star

Every year, about two Earth masses of material flows to the disk of the young star V346 Normae from its surroundings, to eventually end up on the star causing a brightening.

Hubble Views Powerful Galaxy Named 2XMM J143450.5+033843

Not all galaxies have the luxury of possessing a simple moniker or quirky nickname.

Hubble Scopes Out a Galaxy of Stellar Birth

This image displays a galaxy known as ESO 486-21 (with several other background galaxies and foreground stars visible in the field as well).

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.

Orbiting Supermassive Black Holes Confirmed

For the first time ever, astronomers at The University of New Mexico say they've been able to observe and measure the orbital motion between two supermassive black holes hundreds of millions of light years from Earth - a discovery more than a decade in the making.

Betelgeuse As Seen By ALMA

This orange blob shows the nearby star Betelgeuse, as seen by the Atacama Large Millimeter/submillimeter Array (ALMA).

Challenging Theories of Galaxy Evolution

Finding such a galaxy early in the history of the universe challenges the current understanding of how massive galaxies form and evolve, say researchers.

Star's Birth May Have Triggered Another Star's Birth

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.

Watch Engineers Work on the Webb Space Telescope

Now that NASA's James Webb Space Telescope has moved to NASA's Johnson Space Center in Houston, Texas, a special Webb camera was installed there to continue providing daily video feeds on the telescope's progress.
