Cosmic dust clouds obscure hidden ‘empty space’ galaxies

In a case of celestial serendipity, an international team of researchers has discovered two hidden galaxies in empty space – the area devoid of almost anything at all – beaming out from behind huge clouds of space dust. One of them represents the most distant dust-obscured galaxies known to date. The discovery suggests that our … Continue reading Cosmic dust clouds obscure hidden ‘empty space’ galaxies

Move over Dr Who: We can travel the (virtual) universe too

An international team of researchers has generated an entire virtual universe and uploaded it to the “cloud”. They then made it freely available to anyone who wants to explore the cosmos without the pesky laws of physics (and economics) getting in their way. Uchuu (meaning “outer space” in Japanese) is the largest and most realistic … Continue reading Move over Dr Who: We can travel the (virtual) universe too

Hungry galaxies grow fat on their neighbours

Galaxies grow large by eating their smaller neighbours, new research reveals.Exactly how massive galaxies grow so big is poorly understood, not least because they swell over billions of years. Now, a combination of observation and modelling from researchers, led by UNSW’s Anshu Gupta from Australia’s ARC Centre of Excellence for All Sky Astrophysics in 3 … Continue reading Hungry galaxies grow fat on their neighbours
