Australia’s part in the global effort to discover gravitational waves
Paul Lasky and Letizia Sammut, The Conversation, February 12 2016
The discovery of gravitational waves involved a team of more than 1,000 scientists from across the globe, including Australia. So how does such an international collaboration work?
Explainer: what is a neutron star?
Duncan Galloway, The Conversation, September 1 2015
They’re are the overachievers of the universe: incredibly dense but very small when compared to others stars. So how much do we know about the extreme behaviour of neutron stars?
Young star theory forged from a near miss with a giant black hole
Daniel Price, The Conversation, March 27 2015
The best observations yet of a mysterious gas cloud that was heading for the black hole at the heart of our Mily Way reveal it may have more stellar origins.
Giant sunspot returns – and it’s bigger and badder than ever
Paul Cally, The Conversation, November 12 2014
The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger.
Explainer: how do satellites orbit the Earth?
Michael Brown, The Conversation, August 11 2014
Satellites in orbit are routinely used for communication, imaging and navigation – yet many people don’t understand how these satellites remain in space.
Dating the sun’s prenatal history can help find life on other planets
Maria Lugaro and Alexander Heger, The Conversation, August 8 2014
Without the sun, there would be no Earth – but amazingly, we don’t know the finer details about the prenatal history of our sun, where it was born and if other stars in our galaxy share a similar history.
The changing colours of the universe
Michael Brown, The Conversation, April 28 2014
Take a look at a Hubble image of the distant universe and you will see hundreds of galaxies that come in a variety of shapes and colours. So what are we seeing?
A solar magnetic reversal means there’s no need to flip out – yet
Paul Cally, The Conversation, August 21 2013
You may have read the sun’s magnetic field is heading for a change in field polarity - meaning it will flip upside down - and could have ripple effects throughout the entire solar system.
Explainer: light years and units for the stars
Michael Brown, The Conversation, August 20 2013
‘Space is Big. Really Big.’ The Hitchhiker’s Guide to the Galaxy pretty much nailed space with those five words. And space is so really big that our earthly measures of distance struggle.
A stellar mid-life crisis: why do some cluster stars die early?
Simon Campbell, The Conversation, May 30 2013
It was written in the stars all along, but we’ve just found out: a whopping 70% of stars in a widely-studied cluster die before reaching old age which, for stars, is the most productive stage of their lives.
Across the Zooniverse – keeping an eye on citizen astronomy
Kevin Pimblett, The Conversation, April 19 2013
Amateur astronomers in Russia made a discovery last week any professional would envy - it seems they may have identified the remnants of the ill-fated Soviet Mars 3 lander, 30 years after it lost contact with Earth.
Science of Dr. Who
Allie Ford, Canberra Times, August 10 2012
Dr. Allie Ford talks about the “Science of Dr. Who” in a series of presentations looking at the scientific possibility of Dr. Who.
Diamond planet found (if you like it then you should have put a ring on it)
Duncan Galloway, The Conversation, August 26 2011
A planet has been found in our Milky Way galaxy that may be made entirely of diamond.
Explainer: a beginner’s guide to the galaxy
Michael Brown, The Conversation, April 7 2011
Where are we within our galaxy? How did our galaxy form? How did it evolve over the aeons? Astronomers have been asking these questions for the past century, and have recently begun discerning the answers.
