Alien worlds, once hidden from knowledge, are now being discovered in droves, stunning astronomers with their unique features and sheer numbers. The discoveries are so common that more and more don&#39;t even get reported outside scientific circles.

Astronomers using NASA's Chandra X-ray Observatory have discovered one of the fastest stars ever seen--a &quot;cosmic cannonball&quot; that is challenging theories to explain its blistering speed.

In just a short amount of time, NASA's Spitzer Space Telescope has bagged thousands of previously unknown dwarf galaxies in a giant cluster of galaxies. Despite their diminutive sizes, dwarf galaxies play a crucial role in cosmic evolution.

Twenty years ago, astronomers witnessed one of the brightest stellar explosions in more than 400 years. The titanic supernova, called SN 1987A, blazed with the power of 100 million suns for several months following its discovery on Feb.

News from the galactic centre Astronomers using ESA's Integral gamma-ray observatory have spotted a massive eruption of gamma rays in the galactic centre. The researchers say the characteristics of the flare indicate that it could be an extremely rare star-black hole binary system, exhibiting behaviour that might only be seen once or twice in a decade.â¦

Black holes are dark secrets, shrouded in churning spacetime and scrunched into points smaller than an atom. In recent years, astronomers have successfully penetrated some of their mysteries, but fundamental questions about what they are and how they work are still unanswered.

The National Aeronautics and Space Administration (Nasa) launched a space observatory named Swift last week to scan the universe for violent celestial explosions that astronomers believe represent the birth screams of black holes.

Cambridge, MA -- Astronomers are hunting an elusive target: rogue black holes that have been ejected from the centers of their home galaxies. Some doubted that the quarry could be spotted, since a black hole must be gobbling matter from an accretion disk in order for that matter to shine.

A jet of highly charged radiation from a supermassive black hole at the center of a distant galaxy is blasting another galaxy nearby -- an act of galactic violence that astronomers said yesterday they have never seen before.
