Bizarre supernova completely normal in every way, find astronomers
A nearby white dwarf went supernova in 2011, giving scientists an unprecedented look at a rare Type Ia supernova. They discovered that it's remarkably, stunningly, perfectly 'normal.'
-
Little Green Men? New type of star breaks all the pulsar rules
A newly discovered group of 36 stars seems to be pulsating regularly, but only once every 2 to 20 hours – many times slower than any known pulsar.
-
Colossal hydrogen bridge between galaxies could be fuel line for new stars
Researchers studying a filament of hydrogen between the Andromeda and Triangulum galaxies found rotating clumps of gas the size of dwarf galaxies. But questions remain.
-
Record-breaking star explosion is most powerful ever seen
Two NASA space telescopes have captured what appears to be the most powerful star explosion ever detected, a cosmic event so luminous that scientists dubbed it 'eye-wateringly bright' despite being 3.6 billion light-years from Earth.
-
Einstein's theory of general relativity gets most extreme test yet
In their efforts to crack the mysteries of gravity, scientists continue to probe Albert Einstein's theory of general relativity. The latest test involved a curious binary star system.
-
Astronomers discover the Ed Begley Jr. of galaxies
An international team of researchers have spotted the most fuel-efficient galaxy yet, which converts nearly 100 percent of its hydrogen gas into stars.
-
Alien planet photo: Telescope spots gas giant formation
Alien planet photo: In an astronomical first, a telescope in Chile has spotted the formation of a gas giant in the dust cloud orbiting a nearby star.
-
Giant space lobster? Telescope spots spectacular nebula.
A new image of the nebula NGC 6357 in the Scorpius constellation shows a star nursery that looks distinctly like a cosmic lobster.
-
Cosmic rays' mysterious origin? Supernovae to blame, study confirms.
A team of researchers found the 'unique, smoking-gun signature' of the creation of cosmic rays in the expanding shells cast off by supernovae.
-
Supernova alert! Astronomers spot warning sign
Astronomers have identified the early warning sign of an imminent supernova: a stellar belch that could indicate the star will explode within a month or two.
-
Earth-like planets next door? Prospect could point to 9.6 billion more
A new study calculates that the nearest Earth-like planet may be only 13 light-years away – and argues there may be more habitable planets out there than we thought.

Diamond-studded planet orbits sun-like star (+video)
Resent research found that more than one-third of the newly discovered planet, 55 Cancri e, may be covered in diamonds. This discovery marks the first of a planet so fundamentally different from Earth.
-
Bizarre alien super-Earth planet probably made of diamond
The alien planet, a so-called 'super-Earth,' is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy.
-
Bizarre star spiral may provide glimpse into sun's future
Using the Atacama Large Millimeter/Submillimeter Array in northern Chile, an international team of astronomers found the spiral structure never seen before.
-
Distant galaxy helped tidy up early universe, scientists say
Using data from space telescopes, scientists say they have located a galaxy formed more than 13 billion years ago when the universe was young and still permeated with a fog of hydrogen gas.
-
Cosmic lens reveals galaxy from the dawn of time
This distant, ancient galaxy may have once helped clear out the murky fog that once filled the early universe, scientists added.
-
Dark energy: Can $40m camera help solve its mystery? (+video)
The Dark Energy Camera, on a telescope high in the Chilean desert, is expected to capture 300 million galaxies, 100,000 galaxy clusters, and some 4,000 supernovae over the next five years.
-
Sugar molecules – a building block of life – spotted orbiting star (+video)
Astronomers have spotted molecules of glycolaldehyde, a simple sugar that is one of the ingredients in the formation of RNA, orbiting a star some 400 light years away.
-
Tatooine-like planet: Astronomers spot pair of planets orbiting twin suns (+video)
Tatooine-like planet: In a cosmic first, astronomers have discovered two alien planets orbiting two stars, not unlike Luke Skywalker's home planet in the Star Wars films.
-
Scientists probe mysterious origins of humongous star explosions
Super-luminous supernovas, the biggest known explosions in space, remain shrouded in mystery. But scientists are beginning to understand their origins, which could help explain the creation of heavy elements in the early universe.
-
Astronomers spot humongous 'supermom' galaxy fervently spawning stars (+video)
Astronomers have detected a luminous galaxy some 5.7 billion light years away that produces about 740 new stars each year.
-
The unprecedented Phoenix Galaxy Cluster: How many stars does it form? (+video)
Here's a by-the-numbers look at the Phoenix cluster, which researchers say could yield key insights into how galaxies and colossal clusters evolve:
-
Why a galaxy far, far away has shattered records for birthing stars
Astronomers identify a giant cluster of galaxies 5.7 billion light-years from Earth. At its core new stars are being formed at a rate that could explain how supermassive black holes govern a galaxy's growth.
-
New spiral galaxy image shows pair of supernovae
The European Southern Observatory's (ESO) Very Large Telescope in Chile captured a very detailed image of a galaxy that hosted two supernova explosions within the past 30 years.
