ANU helps find supercluster of galaxies near Milky Way
This is one of the biggest concentrations of galaxies in the Universe - possibly the biggest in the neighbourhood of our Galaxy. ANU Professor Matthew Colless is part of an international team of astronomers that found one of the Universe's biggest superclusters of galaxies near the Milky Way. Professor Colless said the Vela supercluster, which had previously gone undetected as it was hidden by stars and dust in the Milky Way, was a huge mass that influenced the motion of our Galaxy.

Detecting weather on a gas giant exoplanet
Detecting weather on a gas giant exoplanet
Signs of powerful changing winds have been detected on an exoplanet 16 times larger than Earth, according to a team involving UCL scientists. It's the first time that weather systems have been found on a gas giant outside the solar system. Led by the University of Warwick, the researchers discovered that the gas giant HAT-P-7b, which is located over 1000 light years away, is affected by large scale changes in strong winds moving across the planet, likely leading to catastrophic storms.

Researcher and amateur science sleuth find cosmic dust in cities
Researcher and amateur science sleuth find cosmic dust in cities
Scientists have found cosmic dust for the first time in urban places, on rooftops in three of the world's major cities. "When Jon first came to me I was dubious. Many people had reported finding cosmic dust in urban areas before, but when they were analysed scientists found that these particles were all industrial in origin.

Saturn’s bulging core implies moons younger than thought
Saturn's moon Dione, foreground, appears darker than the moon Tethys because it has a lower surface albedo, as shown in a photograph taken from the Cassini spacecraft on March 23, 2010. At the time, Cassini was about 746,000 miles from Dione and about 1.1 million miles from Tethys. Freshly harvested data from NASA's Cassini mission reveals that Saturn's bulging core and twisting gravitational forces offer clues to the ages of the planet's moons.

Cosmic recycling strengthens stellar Spiderweb theory
Eight years ago Dr Nina Hatch , an astronomer at The University of Nottingham , identified a thin haze around a distant galaxy known as the Spiderweb galaxy. She suggested this haze was made up of rapidly forming young stars. But the problem with this research, published in the academic journal Royal Astronomical Society , was that no one knew where this young stellar population could be coming from.

How to monitor global ocean warming - without harming whales
How to monitor global ocean warming - without harming whales
Most of the extra heat trapped by human-generated emissions is ending up in the oceans. But tracking the temperature of the world's oceans to monitor the change is trickier than it might seem. While satellites monitor surface temperature, measuring the ocean's interior temperature poses a logistical challenge.

Chicxulub: a unique crater to elucidate planetary surfaces
The fall of an asteroid in the Yucatán Peninsula (Mexico) 66 million years ago is believed to have caused the extinction of dinosaurs. It also created the Chicxulub impact crater, the only such crater on Earth that still has a peak ring – a type of structure commonly found, in contrast, on the surface of several objects in the Solar System.

Simulations Show Swirling Rings, Whirlpool-Like Structure in Subatomic ’Soup’
International team including Berkeley Lab researcher surprised by complex dynamics in model of quark-gluon plasma At its start, the universe was a superhot melting pot that very briefly served up a particle soup resembling a 'perfect,' frictionless fluid. Scientists have recreated this 'soup,' known as quark-gluon plasma, in high-energy nuclear collisions to better understand our universe's origins and the nature of matter itself.
