Nasa announces new findings relating to the atmosphere of Mars which could give hints about the planet's past and the possibility of life on the red planet
quote:
Mars’s once hospitable atmosphere could have become so dry and cold because bursts from the sun that battered it during its early history, according to new studies released by Nasa.
Measurements from Nasa’s Mars Atmosphere and Volatile Evolution (Maven) mission show that the atmosphere was ripped away by a huge burst of gas and magnetism from the Sun. The results of the mission bring far more detail to scientists’ understanding of how the Martian atmosphere changed during its early life.
When it was younger, Mars was much warmer and wetter — and so potentially far more hospitable to life. But at some point since, it has dried out and become far colder, making it harder to live there and leaving life very rare if it exists at all.
quote:
Another study looked at an aurora that could be seen on Mars’s northern hemisphere. It showed that aurora — which is akin to the Earth’s northern lights — dipped low into the Red Planet’s atmosphere.
Mars’s aurora is probably caused by the magnetic field in the crust, rather than the magnetism of the poles as it is in the Earth.
A third paper announced by Nasa supported the idea that magnetic fields related to the sun were changing the atmosphere on Mars. By analysing occasions when Maven dipped into the atmosphere of Mars and studied its makeup, it found that variations suggested magnetic fields were key to its changes — and that much of that magnetic field was being contributed by Mars’s surface.

The fourth study released by Nasa explored the dust that was found in the Martian atmosphere. Scientists say that there is no process known that could whip dust up so high, and it is not coming from Mars’ moons — and so the dust is likely coming entirely away from the planet.

Why does NASA always release news on Thursdays?

A bunch of nerds all excited about something that 99% of America won't give a shite about.

Already have been saying climate change 30 times.
BUT
Apprently The climate change on Mars is VASTLY different than the climate change on earth (solar winds vs human interaction)

Did they find another penis rock formation?

So the damn sun and magnetic forces are a threat to our atmosphere!?!?
We have to stop the sun from doing more harm to our environment while we still can. The sun doesn't care about us. It wants to kill us!
BOYCOTT THE SUN!!
PROTEST MAGNETISM!!!

Wait, the sun's energy output is not steady-state?
It's a good thing this varying output has no effect on earth's climate.

We just need to tax the sun. Problem solved.

So, the sun actually has an effect on the climate/atmosphere. Who woulda thunk it?
I thought all along it was my F250.

Damn, that went right over my head.
