Together with my colleague we started this search for planets, we showed it was possible to study them.". Under current conditions, we cannot live on any of the planets. We do nothing to advance the universe and even despoil our planet. We can’t see the exoplanet, but we can see the star move. Humans will never migrate to a planet outside of Earth's solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said Wednesday. For centuries, fictional depictions of planets orbiting other stars have fired our imagination. Mayor was a professor at Geneva University and Queloz was his doctorate student, when they made the discovery which started a revolution in astronomy. An example of one such creature is shown in this picture. Will we be able to live on other planets? It has a very thick atmosphere due to an irreversible greenhouse affect. Why is there no oxygen in space? The reason that we can’t live on most other planets is because they don’t supply the basic human needs (Water, oxygen and food.) It may not even have a atmosphere. Atmosphere - our earth has a quality of atmosphere which contains o2 lot for our respiration. Down in Front! Other worlds could be filled with even more flourishing life than we have on Earth, scientists have said. Why are the stars different colours and why do they change colours? googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Mayor and his colleague Didier Queloz were on Tuesday awarded the Nobel Prize for Physics for their research refining techniques to detect so-called exoplanets. With a possible launch in the mid 2020s, WFIRST, or the Wide-Field Infrared Survey Telescope, could zero in on a distant planet’s reflected light to detect the signatures of oxygen, water vapor, or some other powerful indication of possible life. The Gravity is 62% lower than earths gravity. Why can't we live on other planets? That's why NASA is working on a Mars 2020 rover. The reason that we can’t live on most other planets is because they don’t supply the basic human needs (Water, oxygen and food.) "We don't know! * Dr. Faulkner is Professor of Astronomy/Physics at the University of South Carolina Lancaster. 0. Heck, Stern said — these critters live so deep, we can't even expect them to know that there's a sky over their heads. When an exoplanet passes in front of its star, we can't see the planet, but we can see the starlight dim. Other planet may have air and water (or we could take it there) but we would have to get there first. "Sometime in the next decade, we … Humans on Mars will be living in what is essentially an enclosure, like animals in a zoo. There is no sign of any life – plants or intelligent Martians - on the planet. Why study exoplanets? Mars surface conditions pretty much preclude the existence of liquid water.
