'I think that we will discover life outside of Earth in my lifetime. If not that, then in your lifetime,' one astronomer told us.
The Earth may be crawling with undiscovered creatures with a different biochemistry to life as we know it.
Deeply divisive issues like Brexit are seeping into the way people interact with one another, undermining trust and tolerance of others.
NASA’s Europa Clipper mission just got the green light - here’s what it could achieve.
Listen up, conspiracy theorists – it is virtually impossible that there could be alien visitors on Earth.
For the first time, an instrument orbiting Mars and a rover on the surface have detected methane simultaneously – raising hopes for finding life on the red planet.
There’s enough dissolved oxygen in the salty lake below Mars’ surface to support simple lifeforms such as sponges. Here’s what that means for space exploration.
If we find microbes on Mars, it will be difficult to exclude the possibility that we have accidentally brought them there from Earth.
Scientists discover rare molecules on Titan which suggests it’s creating the building blocks of life.
Astronomers in Puerto Rico have picked up signal from a faint star that’s not like anything they’ve seen before.
Musk dismisses one of the main technical challenges of being on the Martian surface: the temperature.
We continue to search for intelligent life elsewhere in the universe. But if we find ET there are those who question whether we should make contact or not.
Mysterious radiation that appears to come from star HD 164595 is more likely to have a terrestrial origin.
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?
A technological revolution in astronomical observations could be the key to understanding the perplexing phenonenon known as ‘fast radio bursts’ from outer space.
A new model suggests that elliptical galaxies are more likely to be habitable than spiral galaxies like our own. Does that mean we’re a freak event and elsewhere is teeming with life?
The $100m project to search for aliens will help save observatories from closure and could lead to new astrophysical discoveries.
