Prize-winning Harvard astronomy professor will visit the 成人大片 next week to give a free public talk.

In Australia for the , Professor Kirshner is speaking as part of the public lecture series, presented by the University's School of Chemistry & Physics.

Professor Kirshner is an expert on exploding stars - supernovae - and what they can tell us about the most mysterious component of the universe, 'dark energy'.

He was a member of one of the teams that observed exploding stars halfway across the universe and made a stunning discovery: that the expansion of the universe is speeding up.

The finding was named the top science breakthrough of 1998 by magazine and was a huge turning-point in our understanding of the universe.

'Dark energy' is the name astronomers have given to whatever is making the acceleration speed up - but no-one knows what it actually is.

Astronomers are trying a couple of ways to find out, however.

In his public lecture, Professor Kirshner will explain an astronomers' view of the universe, drawing on his own first-hand account of the discovery of the accelerating universe as a member of the High-Z Supernova Search Team.

He will describe how astronomers are attempting to get a handle on the nature of dark energy, which researchers believe will lead to a new understanding of physics.

An author of more 250 scientific publications, Professor Kirshner has also written for , , , and magazines and is a frequent public speaker on science.

His award-winning popular-level book is now in paperback and has been translated into four languages.

Professor Kirshner's tour of Australia is funded by a administered by the .
