An Australian physicist is unravelling the mystery of how the hot, brilliant stars we see today emerged from our Universe’s “dark age”.

Theoretical physicist Prof Stuart Wyithe is one of the world’s leading thinkers on the Universe as it was 13 billion years ago, when there were no stars or galaxies, just cold gas.
In the next few years astronomers will learn much more as powerful new telescopes come online.
The Universe is definitely getting bigger, faster—and astronomers using the Anglo-Australian Telescope in NSW have confirmed it.

The results are now in for WiggleZ, a survey of the night sky, spanning 200,000 galaxies and billions of years of cosmic history.
“This puts a nail in it. Clearly the universe is accelerating, and clearly there is something like dark energy,” says Prof Matthew Colless, director of the Australian Astronomical Observatory and a member of the WiggleZ team. Continue reading Massive galaxy survey confirms accelerating Universe→
