Scopes will see sky bubbling with exploding stars

It is hard to imagine that any astronomical phenomenon could escape our latest and most powerful telescopes, but an international research team has now forecast some of the exotic discoveries that will only be able to be studied with the forthcoming Square Kilometre...

Computers beat brainpower in counting stars

A team of University of Sydney astronomers has developed a new way to automatically classify huge numbers of astronomical objects, and to discover new, exotic ones almost as soon as they happen. Massive torrents of raw data are now collected by telescopes on a daily...

Newton’s gravity unchanged over cosmic time

Australian astronomers have combined all observations of supernovae ever made to determine that the strength of gravity has remained unchanged over the last nine billion years. Newton’s gravitational constant, known as G, describes the attractive force between two...

Critical mass not needed for supernova explosions

Astronomers searching for clues about dark energy, the mysterious force that is speeding up the expansion of the Universe, have uncovered new evidence about the nature of supernovae, finding many are lighter than scientists had expected. The findings, from an...

Fat or flat – getting galaxies into shape

Australian astronomers have discovered what makes some spiral galaxies fat and bulging while others are flat discs — and it’s all about how fast they spin. The research, led by the International Centre for Radio Astronomy Research (ICRAR) in Perth, found that...
