The James Webb space telescope is making the headlines again – this time completing its first chemical inventory of a distant, exotic world.
New telescope allows us to study the atmospheres of planets orbiting stars other than our Sun in unprecedented detail.
We should not rule out taking a closer look at exoplanets that have a poorly oxygenated atmosphere.
The European space agency will need both a launch vehicle and a lander platform to launch its ExoMars rover without help from Russia.
AI loves to cheat, but new research shows it doesn’t do so when analysing the atmospheres of exoplanets.
Even if aliens exist, are intelligent like humans and interested in making contact with us, what are the chances they’ll be close enough for us to hear them screaming their presence into the cosmos?
There’s a good reason why so many scientists disagree with claims that Earth has been visited by aliens.
Americans who believe aliens have visited Earth are more likely than disbelievers to say that Joe Biden is not the legitimate winner of the 2020 presidential election.
Methane gas in the atmosphere is a tantalising hint suggesting that life could exists on Mars.
If China succeeds, it will be the first country ever to visit and land on Mars on its first try.
Aliens might want to contact us for the same reasons we are looking for them.
One way forward would be to abandon the traditional approach of using single-dish telescopes for SETI.
Considering what we know about the key ingredients for life’s formation on Earth, here are three explanations for how this process may have occurred on our sister planet.
The clouds of Venus may harbour alien life. But where else?
Scientists don’t claim to have evidence of life on Venus but they have ruled out pretty much everything else.
The Perseverance rover onboard Mars
2020 is our best bet for finding life on the red planet.
Pluto began hot inside, study of its surface fractures suggests
Evolution seems to lead to increasing complexity of species. But perhaps a dominant, intelligent species like humans will always end up destroying itself.
New research expands the pool of habitable worlds to include super-Earths with hydrogen-rich atmospheres.
