At first sight the planet Mars(火星)does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles(161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems ...

Does Mercury have extinct volcanoes? Are there giant volcanoes on Mercury? Does Neptune have volcanoes or craters? Does Mercury have a magnetosphere? Does Mars have volcanoes? Does Venus have volcanoes? Does Venus have active volcanoes? Does Uranus have any volcanoes?
The scientists subjected whole S. caninervis plants to conditions typically found on Mars: high doses of gamma radiation, low oxygen, extreme cold and drought. They report that the plants could withstand combinations of these conditions, even losing over 98% of their water content and still bounc...

The atmosphere of the Earth is held in place by its gravity, and its a good thing for us that it is. All of the planets in our solar system have an atmosphere of some kind, though Earth is the only planet that has free oxygen in the atmosphere....
The quest for signatures of ancient and/or present-day life on Mars is an important driving force in modern Mars science and exploration. The reasons for this have been spelled out in detail elsewhere, such as in the 2013-2022 Planetary Science decadal survey. We do not question the ...
