The increasingly rapid pace of exoplanet discoveries must mean it is only a matter of time until astronomers find another Earth.

Astronomers were looking forward to the first high-res X-ray spectra from space, and all they would tell us about the cosmos. But unknown disaster seems to have befallen the Japanese satellite.

The universe looks very different with X-ray vision, revealing some of the most energetic interactions in our galaxy. Japan's new Hitomi telescope will help us see these wonders.

Satellite imaging can locate mosquito-friendly environments, allowing us to predict the advance of diseases they carry.
To international condemnation and beyond!
Why is it so hard to imagine that North Korea might have perfectly sane reasons for going into space?
It’s all a matter of perspective.

Former PM's business advisor Maurice Newman recently claimed that satellite temperature data tell a different story to data collected on the ground. He's right - but that's how it's meant to be.
Lining up potential pitfalls: nonexperts and computers may misinterpret the vertical line in this image as a natural feature rather than a result of a mosaic compilation of multiple satellite images.
Expert image analysts have an important role to play, even in an age of computer interpretation and crowdsourcing.
We need to find a way to break through the potentially disastrous stalemate wherever everyone waits for someone else to clear up the junk in orbit.
Rural internet users are about to have two satellites launched as part of the nbn.
nbn is set to launch two satellites to bring high speed broadband to rural Australia. Here's how they work.
Nowcasting is a system using satellite images to obtain real-time information before bad weather arrives.
Being able to predict the weather can save lives. Using new technology forecasters are able to provide realtime warning of bad weather ahead.
It looks mean from this close, but it’s still damaging when it reaches Earth.

Satellites are vital and vulnerable - we need to plan for a worst case scenario.
The future of space travel?
A prototype solar sailing satellite has just successfully been deployed in orbit, pointing the way to the future of space travel.
Space endeavours require capital. And for most African countries, capital is a limited commodity.
Many do not associate Africa with the high-tech sphere of "space". However, in recent years, many countries on the continent have woken up to the potential and usefulness of space technology.
Progress M27-M will meet the same fate as the European Space Agency’s Jules Verne Automated Transfer Vehicle which broke up on re-entry back in 2008 after a sucesful supply mission to the International Space Station.

After a failed mission to restock the International Space Station, the Russian Progress M-27M spacecraft is set to burn up as it spins back to Earth.
It’s crowded up there - the many objects tracked in low Earth orbit.
Near-Earth orbits are filled with useful satellites, and also flying junk. If we're not careful they may collide - literally.

We're already building satellites that can sit in the palm of your hand. But getting them into orbit can be a challneg, and not only for technical reasons.
Better use of the tech we have could substantially improve search and rescue efforts.
The seas are vast. And they claim vessels in significant numbers. The yachts Cheeki Rafiki, Niña, Munetra, Tenacious are just some of the more high-profile names on a list of lost or capsized vessels which…

Three American soldiers* may have died in Afghanistan’s battle of Takur Ghar because of disruptions caused by plasma bubbles – a form of space weather – according to a new study. Space weather is normally…
Our moon orbits the Earth in the same way satellites do.
Take a look at the moon and it isn’t hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on…
Plenty of space junk out there.

A bright meteor lit up the sky across Australia last night, grabbing the attention of anyone who happened to be outdoors. Seen around 10pm AEST, it was intensely bright and slow moving, with many observers…
