ALIEN life could be producing an Earth-like gas on Venus, our closest space neighbour. • The scorching hell planet would instantly kill a human, with surface temperatures reaching 470C – and pressure so high you'd be crushed alive. • But scientists think the temperate upper cloud layer on Venus could play host to some forms of life. • Supporting that theory is a team of British scientists who have discovered phosphine gas in Venus' atmosphere. • Here on Earth, phosphine is made by the breakdown of organic matter – and the same could be true for Venus. • Now scientists will need to send a probe to Venus to confirm the existence of alien life. • Phosphine can turn up on a planet in many different ways. • It can be created in the atmosphere, on the surface, or below the surface. And it can even be delivered from another planet. • On Venus, the phosphine was detected around 60km above the surface – in the cloudy atmosphere. • And scientists say it's unclear how this could happen without help from alien life. • Sadly, there's no 100% guarantee that life is hiding away on Venus – yet. • We emphasise that the detection of phosphine is not robust evidence for life, said Professor Jane Greaves, of Cardiff University, who led the team that made the discovery. • However, we have ruled out many chemical routes to phosphine, with the most likely ones falling short by four to eight orders of magnitude. • Phosphine is widely accepted as being a promising sign of life , when found in a rocky planet's atmosphere. • Traces of phosphine in Earth's atmosphere are directly linked to human and microbial activity. • And it's found on other planets too. • On the giant gas planets in our Solar System, phosphine is produced at deep atmospheric layers – and is then dredged upwards by convection. • But on rocky planets like Venus, the solid surface should act as a barrier – preventing this mechanism. • Read more • Sign of LIFE on Venus in extraordinary discovery of Earth-like phosphine gas in atmosphere • https://www.thesun.co.uk/tech/1266440... • From Brexit breaking news to HD movie trailers, The Sun newspaper brings you the latest news videos and explainers from the UK and around the world. • • Become a Sun Subscriber and hit the bell to be the first to know • • Read The Sun: http://www.thesun.co.uk • Like The Sun on Facebook: / thesun • Follow The Sun on Twitter: / thesun • Subscribe to The Sun on Snapchat: / 1633225139
