The gas cloud where stars are born

Using a telescope installed at the driest place on earth - Ridge A in Antarctica – a UNSW-led team of researchers has identified a giant gas cloud which appears to be in an early stage of formation. Giant clouds of molecular gas – the most massive objects in our galaxy – are the birthplaces of stars.

Mapping the stars of the Milky Way

With a final, modest, thruster burn yesterday afternoon, ESA’s billion-star surveyor finalised its entry into orbit around ‘L2’, a virtual point far out in space. But how do you orbit nothing? And who can show you how to get there, anyway?

Coldest Brown Dwarfs blur lines between stars and planets

Astronomers are constantly on the hunt for ever-colder star-like bodies, and two years ago a new class of objects was discovered by researchers using NASA's WISE space telescope. However, until now no one has known exactly how cool their surfaces really are - some evidence suggested they could be room temperature.

Studying stars by stellar proxy

A University of Washington astronomer is using Earth's interstellar neighbors to learn the nature of certain stars too far away to be directly measured or observed, and the planets they may host.

This galaxy turns gas into stars

Astronomers have discovered a galaxy transforming gas into stars with almost 100 percent efficiency - a rare phase of galaxy evolution that is the most extreme yet observed.

MIT team sees the very first stars

Researchers at MIT, the California Institute of Technology, and the University of California at San Diego have peered so far back in time that they've found matter that pre-dates the creation of heavy elements.

The ancient stars of NGC 6362

The ESO’s La Silla Observatory in Chile recently captured a colorful view of the globular star cluster NGC 6362.

Pair of planets found orbiting twin suns

NASA's Kepler mission has for the first time discovered multiple planets orbiting a pair of stars, showing it's possible for more than one planet to be formed and survive in such a chaotic environment.

Massive Phoenix cluster forms stars at a record pace



Astronomers have identified an "extraordinary" galaxy cluster which scientists describe as one of largest objects in the universe.



Mystery of monster stars explained

Since the 2010 discovery of four stars 300 times as massive as our sun, astronomers have been scratching their heads over how they could have come to exist.

A green getaway amidst a sea of trees and stars

Admit it: you've always dreamed of living in a tree house. 



Team spots 'impossible' binary stars

A team of astronomers has discovered four pairs of stars that they thought couldn't exist, with the stars in each pair orbiting one another in less than four hours.

Hubble snaps a vapor of stars

Relatively few galaxies are endowed with the sweeping, luminous spiral arms or brightly glowing center of our own Milky Way galaxy. 



Milky Way still rings like a bell after cosmic crash

Our galaxy is still reverberating from a strike by a small galaxy or massive dark matter structure.

Sandstorms discovered in space

Astronomers believe they've solved the mystery of how dying stars disintegrate.

Black holes expand by eating stars

Most galaxies, including our own Milky Way, feature a supermassive black hole at their center weighing millions to billions of suns. 

But how do those black holes grow so hefty?

The glittering stars of Messier 9

Messier 9 can best be described as a globular cluster, a roughly spherical swarm of stars that lies approximately 25,000 light-years from Earth.

The stars of the Antlia Dwarf galaxy

The numerous faint stars that comprise the Antlia Dwarf galaxy - first discovered in 1997 - are more than four million light-years from Earth.

Almost all Milky Way stars have planets

The vast majority of stars in our Milky Way galaxy have at least one planet orbiting them, astronomers have concluded - and lots of these could be comparatively Earth-like.

NASA's Hubble observes "tiny" galaxies bursting with stars


NASA's Hubble Space Telescope has identified 18 "tiny" galaxies which existed 9 billion years ago and are brimming with star birth.
