航空宇宙局 has identified a gas on 火星 that is produced by living creatures on Earth, baffling scientists about what could be hiding in the Red 惑星.

The Curiosity Rover （悪事，秘密などを）発見するd a 安定した stream of methane coming from 強風 噴火口，クレーター, appearing at different times of day and fluctuating 季節的に ? いつかs reaching 40 times higher than usual.

While 航空宇宙局 has yet to find life on the Martian world, scientists believe the source comes from 深い in the ground.

The team has 示唆するd that methane could be encased under solidified salt and only seep out when 気温s rise on 火星 - or when Curiosity rolls over the crust and 割れ目s it.

On Earth, this simple 分子, made up of one 炭素 原子 and four hydrogen 原子s, is usually a 調印する of life: gas passed by animals as they digest food.?

NASA's Curiosity Mars Rover detected methane coming from near Gale Crater - but not all the time. Scientists wanted to know why.

Scientists used this sample of Mars's soil to run an experiment on how it forms a crust, trapping methane under the planet's surface during the day.
