It’s been the defining question of high-energy astrophysics for the past century: where do cosmic rays come from? New findings from the IceCube Neutrino Observatory at the South Pole have brought us closer…
Last week’s Global Atheist Convention and debates between prominent atheists and theologians in the Australian media has seen arguments about the existence of God getting a thorough airing. In my view…
As of today, the world might have changed forever. A fundamental assumption underpinning much of modern geochemistry is that the earth has the same composition as a class of meteorites called chondrites…
In a result which has baffled astronomers at NASA’s Chandra X-ray Observatory, dark matter has been observed separating from…
When the Obama administration announced its proposed NASA budget in February, astronomers worldwide breathed a sigh of relief. Despite significant cuts in other areas, funding for the James Webb Space…
The collision of several, massive galaxy clusters has left behind a clump of dark matter, potentially challenging existing…
Professor Michael Ashley recently returned from Antarctica where he deployed a telescope to one of the most remote locations on Earth – a place known as Ridge A, 850km from the South Pole. This is the…
X-rays of the moon have shown that, unlike Earth, our rocky satellite has no active volcanos, and hasn’t for billions of…
Ever since they were discovered accidentally in the 1960s, gamma ray bursts (GRBs) have continued to amaze and puzzle astronomers worldwide. In nearly 50 years of research there seem to have been more…
The Intermediate Mass Black Hole HLX-1 is surrounded by a very young massive cluster of stars, researchers from the University…
Professor Michael Ashley recently returned from Antarctica where he was deploying a telescope to one of the most remote locations on Earth – a place known as Ridge A, 850km from the South Pole. This is…
Double-star systems called X-ray binaries may give insight into the physics of black holes. X-ray binaries are double-star…
Astronomers have used 41,000 individual measurements to map the magnetic fields of our galaxy in greater detail than ever…
Professor Michael Ashley is currently in Antarctica to deploy a telescope to one of the most remote locations on Earth – a place known as Ridge A, some 850km from the South Pole. This is the second instalment…
The star with the fastest rotation ever recorded has been discovered by researchers at the University of California, Santa…
The core of a red giant star spins at a rate ten times faster than its surface, an international team of researchers has…
Today, the University of Melbourne’s Professor Stuart Wyithe was awarded the 2011 Malcolm McIntosh Prize for Physical Scientist of the Year for his work on the origin of galaxies. The multi-award winning…
An astrophysicist from the Australian National University has jointly won the 2011 Nobel Prize in Physics for his part in the discovery that the expansion of the Universe is accelerating. Harvard-educated…
It’s one of the most famous and evocative images in cinematic history – Luke Skywalker gazing out at the twin suns of Tatooine as they set, in the original Star Wars movie, A New Hope. Such a view would…
