The probe will carry instruments to measure water, dust and other molecules in the planet's atmosphere, in an attempt to learn how Mars transitioned from wet and warm to dry and dusty.

Helling used the model to simulate how dust whirls and swirls around in the atmospheres of brown dwarfs: gassy bodies too big and warm to be planets, but too small and cool to be stars.

These days the Martian atmosphere is thin and about 95 per cent CO2, but scientists think that 3 or 4 billion years ago the planet's gassy envelope was much thicker and even richer in carbon, making its surface warm enough to support liquid water — and possibly life.

An active hydrological cycle would have required a warmer climate in the planet's early history and therefore a thicker atmosphere, one capable of creating a strong greenhouse effect.

The simulations also suggest that the removal of excess carbon dioxide from the atmosphere by natural processes on land and in the ocean will become less efficient as the planet warms.

The scant radiation that did reach the planet was trapped by the atmosphere, resulting in warm, wet periods.

In a paper published in Geophysical Research Letters, researchers found that interactions between methane, carbon dioxide and hydrogen in the early Martian atmosphere may have created warm periods when the planet could support liquid water on the surface.

Such stars used to be dismissed because any planet orbiting close enough to stay warm gets locked into synchronous rotation: One hemisphere perpetually faces the star, growing sizzling hot, while the other side points away, becoming so cold that any atmosphere would freeze onto the surface.

But for planetary scientists, Jupiter's most distinctive mystery may be what's called the «energy crisis» of its upper atmosphere: how do temperatures average about as warm as Earth's even though the enormous planet is more than fives times further away from the sun?

The planets of the TRAPPIST - 1 system could be complex worlds with volcanoes, atmospheres and warm subsurface oceans.

The Red Planet's thin atmosphere of carbon dioxide can't retain enough heat for water to flow on the planet, but new calculations suggest how it was once Planet's thin atmosphere of carbon dioxide can't retain enough heat for water to flow on the planet, but new calculations suggest how it was once planet, but new calculations suggest how it was once warmer

But some of that heat gets blocked by those pesky carbon dioxide molecules building up in the atmosphere — inexorably warming our planet.

It may seem surprising to people, but you can look at something like Mars, which has a very thin atmosphere, and you can look at something like Venus which we tend to think of as sort of having this rather heavy, clouded atmosphere, which [is] hellishly warm because of runaway greenhouse effect, and on both of those planets you are seeing this phenomenon of the atmosphere leaking away, is actually what directly has led to those very different outcomes for those planets; the specifics of what happened as the atmosphere started to go in each case [made] all the difference.

Logically, say Howarth and other researchers interested in how much methane leaks to the atmosphere, a higher lost and unaccounted for percentage would mean more gas is escaping the system and warming the planet.
