RIP E.T. – alien life on most exoplanets dies young

Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.

Is Alpha Centauri the right place to search for life elsewhere?

A US$100-million plan has been announced to send tiny probes out in space in search of life elsewhere in the universe. But are they looking in the right place?

Cloudy with a chance of life: how to find alien life on distant exoplanets

A hint of oxygen and a whiff of methane in a distant exoplanet's atmosphere may be the first evidence we discover of alien life.
Is this what we’re seeing around KIC 8462852 - a colossal megastructure built by alien intelligence? Probably not. The reality might be even more interesting. Kevin Gill/Flickr

Whatever the strangest star in the galaxy is, it’s sure to be amazing

There's a lot of speculation about a star behaving strangely in our galaxy. But even if it's not evidence of alien intelligence, it's sure to be an amazing discovery.

The hunt for ET will boost Australian astronomy

The Parkes radio telescope is part of the US$100 million search for life elsewhere in the universe, but the investment will also benefit other space research at The Dish.

There’s no evidence to suggest there is life on Comet 67P

As far as underwhelming headlines go: “No Alien Life Found on Comet” must rank very close to the top. An article with this title appeared in the Guardian on July 6 in response to a story claiming that…

Alien worlds: most stars have planets in the habitable zone

The search for life on other planets gets a boost thanks to an old calculation that found Uranus in our solar system.
