A top university scientist believes we could be able to see aliens in the future with thanks to new powerful telescopes.
Cambridge University scientist Dr Emily Mitchell reckons devices such as the James Webb Space Telescope will allow scientists to analyse the atmospheres of other planets in great detail.
A closer look at the planets will reveal more about their birth and evolution, stars, and galaxies.
Dr Mitchell has suggested that alien life may be detected in the next few decades by identifying patterns known as biosignatures.
New powerful telescopes allow the analysis of starlight as it passes through a planet's atmosphere, revealing information about its chemical make-up.
This chemical composition may be changed in the presence of certain gases to evidence past or present life - known as a biosignature.
