Physicist Brian Cox said, Mars now looks like a rock desert, which may have been a real paradise with waterfalls and rivers.
In the all-new series that explored our solar history in the past 4.5 billion years, Professor Brian Cox has revealed that extraterrestrial life can hide in a 1500km-wide volcano Fire.
Mars once had life and still exists but in other forms.
The physicist said: 'Most of Mars's water has evaporated and escaped into space, leaving only small traces on the ice all over the planet. There is a crater on Mars called Hellas Basin , with a circumference of 1,500km and a depth of 9km.
Brian Cox argues that the ability of bacteria to hide on this volcanic surface due to high air pressure in the crater basin allows liquid water to exist.
'The air pressure down there is very high, liquid water can exist, so I think it's hard to imagine the bacteria growing from deep beneath the volcanic surface to immerse themselves in the middle sun. noon before crawling down to survive the cold of the Martian night ' , Brian Cox emphasized.
3.5 billion years ago Mars had a greenhouse-rich atmosphere. This is believed to have caused Martian rivers to evaporate into space, leaving only traces, frozen in plaques across the planet, where missions continue to look for the first signs of extraterrestrial life.
