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.
Giant molecular clouds are vast cosmic objects, composed primarily of hydrogen molecules and helium atoms, where new stars and planets are born.
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.
Supernovas -- the violent endings of the brief yet brilliant lives of massive stars -- are among the most cataclysmic events in the cosmos.
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
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.
Not all galaxies have the luxury of possessing a simple moniker or quirky nickname.
This image displays a galaxy known as ESO 486-21 (with several other background galaxies and foreground stars visible in the field as well).
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.
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.
This orange blob shows the nearby star Betelgeuse, as seen by the Atacama Large Millimeter/submillimeter Array (ALMA).
Finding such a galaxy early in the history of the universe challenges the current understanding of how massive galaxies form and evolve, say researchers.
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.
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.
Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes -- though not an identical twin.
