It could be orbiting LHS 2520.
In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.
As the list of known planets beyond our solar system grows, the search for their moons is intensifying. One reason: they might hold the key to finding life elsewhere in the universe.
The search for new objects, including new planets, in our solar system has turned up some interesting finds. There have been a few failures over the years too.
Jupiter had a big influence on how our solar system's planets formed. New research – led by a high school student – tried to nail down how rare Jupiter analogs really are in other planetary systems.
New research gives a clue about what happens when there are two habitable worlds in the same solar system.
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 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.
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.
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.
Why the new exoplanet said to resemble out Earth might just as well resemble Venus or Neptune.
Nimble and cheap commercial science could be the way to get more eyes in the sky.
A new exoplanet has been discovered that is a lot like Earth.
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?
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
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.
After a slow start, Hubble's ultraviolet vision changed the face of astronomy.
