Almost Earth – another step on the road to habitable worlds

Two papers were published today in Nature, each independently revealing that a planet discovered by the Kepler mission is the closest thing we’ve found yet to another Earth. But don’t pack your bags just…
Rocky, water-rich asteroids and similar objects likely delivered the bulk of water on Earth. Now they’re being found well outside our Solar system. Mark A. Garlick, space-art.co.uk, University of Warwick and University of Cambridge

Watery asteroid gobbled up by a white dwarf: implications for life

How will future alien scientists know whether life existed in our solar system? One method may be to sift through the planetary debris left when our sun becomes a white dwarf. Astronomers are doing just…
Not just a pretty planet – Jupiter may provide clues for detecting Earth-like planets. NASA

By Jove! Can climate change lead us to life on other planets?

Thanks to the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report, we’ve recently heard a great deal about how the Earth’s climate is changing. The IPCC’s cautious assessment of the…
New analysis suggests yes, Fomalhaut b is real after all. NASA

New study challenges exoplanet doubts

A new study of data from NASA’s Hubble telescope shows that the distant star Fomalhaut b really is a massive exoplanet and…

Alpha Centauri exoplanet is the closest ever – how was it found?

Earlier this week, a Swiss-based team searching for planets outside our solar system (exoplanets) published a paper in Nature announcing the detection of an Earth-mass planet orbiting the star Alpha Centauri…

New alien planet could support life

Astronomers have discovered an alien planet which could be the best candidate yet for harbouring water and possibly life…
An exoplanet called Fomalhaut b has been photographed in an unexpected spot – so is it even an exoplanet at all? NASA/http://www.nasa.gov

The exoplanet that wasn’t. Or was it?

A distant planet that made its name as the world’s first directly photographed exoplanet is at the centre of an astronomical…

Rare haul: 50 exoplanets and 16 super-Earths found

European astronomers have found 50 distant planets orbiting stars and 16 rocky “super-Earths”, planets that theoretically…
Hundreds of exoplanets have been discovered, but are we any closer to finding life? AAP
