The light shining through an exoplanet’s atmosphere can give us a hint of whether the planet supports life.

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.
Gliese Cc: Artist’s impression of sunset on one of the most Earth-like exoplanets.
Is there another Earth out there? Certainly, there are a few contenders
Recent Martian findings are just the latest discoveries of aurora on other planets, both in and out of our solar system.
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.
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.
Five science (fiction) reasons why you should get to know Doctor Who.

Studying the young, Jupiter-sized planet 51 Eridani b opens a window into our solar system's past.
Who goes there? It’s very unlikely humans ever will, for sure.
HD 219134 b may not be a catchy name - but our new planetary neighbour deserves just as much attention as Earth's cousin, Kepler-452 b.

Nimble and cheap commercial science could be the way to get more eyes in the sky.
Looking for evidence of extraterrestrial intelligent life elsewhere in the universe.

Astronomers have been looking for signs of intelligent life elsewhere in the universe for centuries. But the search has so far found nothing. So what makes this latest hunt so different?
What secrets will space reveal?
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
The 64-metre Parkes Radio telescope will be instrumental in the search for extraterrestrial intelligence.
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.
The galaxies NGC 4038 and NGC 4039, locked in a destructive embrace.
After a slow start, Hubble's ultraviolet vision changed the face of astronomy.
The Kepler satellite discovers exoplanets by measuring the light drop from a star when a planet moves in front of it. Maths can uncover many more exoplanets.

The search for life on other planets gets a boost thanks to an old calculation that found Uranus in our solar system.
Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone.
One to three planets in habitable zones around stars in our galaxy could sustain life.

One of the crucial variables in calculating the likelihood that alien life exists elsewhere in our galaxy is the number of stars that possess planetary systems, and the proportion of those planets that…
At the winter meeting of the American Astronomical Society earlier this month, the NASA Kepler Space Telescope team announced its 1,000th discovery of a planet outside our solar system. This brings the…
Artist’s impression of the planet Kepler 62-f which could lie in the habitable zone of its host star 1,200 light-years from Earth in the constellation Lyra.
More than 1,000 exoplanets have now been discovered by the Kepler Space Telescope, announced NASA this month, and the figure continues to climb. Three of the newly confirmed Kepler planets are thought…

When it comes to finding the right kind of planet to target in the search for life elsewhere in the universe, the size of the planet matters. All planets are believed to form by a process of competitive…

Every so often our Earth encounters a large chunk of space debris which reminds us that our solar system still contains plenty of debris that could potentially have an impact on life on Earth. While the…
In the coming years, many planets that could host life will be discovered. But which will we target in the search for life elsewhere?
In the search for life beyond our solar system, we need to consider the system in which a planet moves, including the other planets and assorted debris that accompany it on its journey through the cosmos…
