Australia’s part in 50 years of space exploration with NASA

Who can forget the hit movie The Dish and Australia’s role in beaming the first live television pictures of man’s first landing on the moon? Well, the filmmakers did play with the truth a bit but it did…

Explainer: how do you find exoplanets?

Astronomers didn’t know, 20 years ago, whether planets existed around any stars other than the Sun. All that changed in 1995 with the discovery of an exoplanet orbiting the star 51 Pegasi. And by the beginning…

Explosive volcanoes light up Mercury’s deep past

Mercury has long been a mystery to scientists. Until recently, knowledge of the planet was limited to the grey, patchy landscape revealed by the Mariner 10 probe, NASA’s first mission to Mercury in the…

For our future in space, China must aim further than the Moon

A famous picture in the English edition of Newton’s “Principia” shows cannon balls being fired from the top of a mountain. If they go fast enough, their trajectory curves downward no more steeply than…

How Twitter fans kept NASA alive during the US shutdown

Now that the US government is back in business, all “non-essential” services will resume. For 15 days we went without NASA’s full operation, US Antarctic research and federally-funded clinical studies…

Mega-canyon discovered beneath Greenland ice sheet

A previously unknown canyon has been discovered in Greenland, hidden beneath the ice. It is at least 750 kilometres long. To put that in perspective, imagine a ten kilometre wide gorge, up to 800 metres…

The end of Kepler? That would be universally bad

As I write this, engineers at NASA and Ball Aerospace & Technologies have their fingers crossed they’ll be able to restart the stricken Kepler space observatory, which has been in hibernation mode…

Clearing the air: the hidden wonders of indoor plants

It may come as a surprise but air pollution levels indoors are almost always higher than outside, even in busy city centres. Even more surprising is that indoor plants have the ability to mitigate high…

Explainer: the International Space Station

As the most visible man-made object in the night sky the International Space Station (ISS) is of significance to humankind. It takes humans from being explorers of space to being residents of space. The…

Buy, sell, lift-off: the global economy is going interplanetary

Harvesting space resources will raise living standards worldwide, without further damaging Earth. So how can those resources be tapped in a way that will produce a return on investment? That question may…

Looking for planets just like Earth

University of Auckland scientists have proposed a new way to find planets like Earth. The research strategy includes the…

New light on dark matter: space station magnet attracts praise

Nobel prizewinner Samuel Ting, early this morning (AEDT), announced the first results from the Alpha Magnetic Spectrometer (AMS) search for dark matter. The findings, published in Physical Review Letters…

Satellite of love: our on-off relationship with the moon

Like all relationships, our association with the moon has had its ups and downs. In this series we’ve talked about the nature of the satellite and how we think it was formed - in a giant collision that…

Crash – a-ah! Our moon has a history of violence

The more we learn about the formation and evolution of our solar system, the more we realise it was far from a sedate, gentle process. Everywhere we look we find evidence the final stages of planetary…

I see the moon: introducing our nearest neighbour

The moon. Our nearest neighbour. The main source of the ocean’s tides, and a beacon that drives the lives of animals across the globe. And also, to date, the only object beyond Earth on which humans have…

NASA discovers a new radiation belt around Earth

NASA revealed this morning (AEST) that its Van Allen Probes have discovered a third, previously unknown, radiation belt around Earth. The belt appears to be transient, depending strongly on solar activity…
