If the signs are right, fundamental equations of cosmology may need altering. waljoris

Is life on Earth due to a quirk in the laws of physics?

A radical discovery by my colleagues and I – reported this week in Physical Review Letters – could help explain why it was possible for life (at least as we know it) to develop on Earth, but not in other…
Finding quasars will help us understand how galaxies were formed. NASA

Back to where we started: tracing the origins of galaxies

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…
Professor Brian Schmidt helped discover that the expansion of the Universe is accelerating. Belinda Pratten

Australian astrophysicist wins Nobel Prize

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…
Australian astronomers have mapped the cosmic filaments that bind the Milky Way together, which may help reveal how galaxies form. Michael Boylan-Kolchin, University of California Irvine

Scientists track silvery threads that feed the Milky Way

Australian astronomers have shed new light on the cosmic filament that binds the Milky Way together, providing new clues on how the galaxy is formed and how it grows. The Milky Way, home to our solar system…
An exoplanet called Fomalhaut b has been photographed in an unexpected spot – so is it even an exoplanet at all? NASA/http://www.nasa.gov

The exoplanet that wasn’t. Or was it?

A distant planet that made its name as the world’s first directly photographed exoplanet is at the centre of an astronomical stoush, after it veered off course and new doubts were raised about its existence…
NASA’s Upper Atmosphere Research Satellite, or UARS, is expected to re-enter Earth’s atmosphere tomorrow afternoon. NASA/http://www.nasa.gov

Look out! NASA space junk to hit Earth tomorrow

A defunct NASA satellite is expected to fall to Earth some time tomorrow afternoon but the US space agency has said it’s not yet clear where the space junk will land. The Upper Atmosphere Research Satellite…

Black hole jets revealed

The innermost parts of a black hole’s active jets have been revealed for the first time. The observation, by NASA scientists…

Rare haul: 50 exoplanets and 16 super-Earths found

European astronomers have found 50 distant planets orbiting stars and 16 rocky “super-Earths”, planets that theoretically could support life. Expolanets, which orbit stars outside our solar system, were…
Science follows certain procedures, but does the media get the signal? CSIRO

Diamond planets, climate change and the scientific method

Recently my colleagues and I announced the discovery of a remarkable planet orbiting a special kind of star known as a pulsar. Based on the planet’s density, and the likely history of its system, we concluded…
Even the Hubble telescope, which took this picture of Bright Spiral Galaxy M81, is not capable of taking the wide-angle shots needed for all sky astrophysics, so new equipment must be invented. NASA http://www.nasa.gov

New all-sky astrophysics research centre to tackle the big questions

Some astronomical questions can only be answered by looking at the whole sky all at once but the technology to do that doesn’t exist yet. Enter the new ARC Centre of Excellence for All-sky Astrophysics…

Skygazers find Earth’s closest young star

Astronomers have a rare new star that is just 27 light years away from Earth, making it the closest young star ever found. AP Columbae, as the red dwarf star has been named, is just 40 million years old…
The Hayabusa space capsule landed in Woomera, South Australia, last year after completing a mission to collect dust from the surface of an asteroid. Science/Hayabusa team

Hayabusa’s asteroid dust reveals space secrets

Asteroid dust collected by a Japanese space capsule that landed in Woomera last year has been matched with samples of meteorites found on Earth, providing new clues about where meteorites came from. The…
