The South Pole Telescope and BICEP telescopes (pictured above) may discover clues that could teach us if there was something else ‘before’ the Big Bang.

Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.
How many times have you heard “get out of the way!” when someone is trying to change the channel?
Even the Voyager spacecraft are controlled remotely, 20 billion kilometres away. It takes 20 hours for instructions to travel from Earth to the spacecraft but we can do it -- using a remote.
An artist’s impression of the surface of the planet orbiting Barnard’s Star.

The new planet is believed to be orbiting Barnard's Star, a red dwarf that's not visible to the naked eye but one of the closest stars to our Solar System.
Nobody knows for sure - but it’s possible.
There are probably more than a million planets in the universe for every single grain of sand on Earth. That's a lot of planets. My guess is that there probably is life elsewhere in the Universe.
The Sun is a star – but it’s not the only one.

There are lots of places where it's much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
The TV drama SeaChange had a huge public impact, which made the town where it was filmed, Barwon Heads on Victoria’s Bellarine Peninsula, a highly desirable destination.
We read about and watch other people moving to the coast or country and, in doing so, sometimes we're persuaded to join the seachangers and treechangers ourselves.
The community environment clearly has a large influence on child development, but exactly which factors are most important?
Research has started to identify the key factors in creating communities that promote good early childhood development.

Whether you call it Planet X or Planet Nine, talk of another planet lurking in our Solar system won't go away. So what does the discovery of a new object – nicknamed "The Goblin" – add to the debate?
Are there greener pastures ahead for gas?
By embracing natural gas made from renewable sources, we can still use gas for heating, cooking and industry, while slashing greenhouse emissions and even keeping much of the same infrastructure.
Lost: Serena Williams after losing to Naomi Osaka in the women’s final of the US Open Tennis Championships, New York.
We need to consider changing the rules of tennis, to make them more consistent across tournaments and players.
Ammunition found at a mounted police camp at Eyre Creek.
For 60 years, native police were deployed in Queensland to 'disperse' Aboriginal communities (a euphemism for systematic killing). Unearthing their camps is a key part of reckoning with the violence of those times.
El casquete polar sur de Marte, visto desde el Mars Global Surveyor. Ahora sabemos que debajo hay un lago de agua líquida.
Los investigadores han encontrado un gran lago de agua salada enterrado a 1,5 kilómetros bajo el casquete polar sur de Marte. ¿Qué significa eso para la vida en el planeta rojo?
Mars’ south polar cap, as seen from Mars Global Surveyor. Buried beneath, we now know, is a lake of liquid water.
Researchers have found evidence of a large lake of salty water, buried 1.5 kilometres beneath the southern polar ice cap on Mars. So what does that mean for life on the red planet?
A moon shadow on Jupiter, the red planet now has a dozen more moons added to the list or such orbiting bodies.
Jupiter now has at least 79 moons, the most for any known planet. But where did these newly discovered moons come from?
People take shelter during the floods in Mozambique.
While disaster insurance would go a long way in averting losses, demand for cover is still lower than expected.
Common beliefs include finding a spiritual essence in nature.
Around 14% of Australians identify as spiritual. It is time they were given the same rights as those belonging to organised religions.
More and more people are being drawn into slums in Ghana’s capital city, Accra.
Self-organisation initiatives taken by slum residents across Africa can help urban development.

NASA’s Transiting Exoplanet Survey Satellite (TESS) successfully launched on a SpaceX Falcon 9.
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.
