Thank you so much! I had so much fun with it.

Yup, tadpole is the first thing I saw. Yessirree.

That is beautiful, such talent. It looks just like the photo!

No doubt there, just look at what happened during the Carrington event. That flare was estimated at X40 and set telegraph lines on fire. If we got hit with one of similar strength today it would be devastating.

Yeah, no kidding. It's doing some weird things. I think it may have factored into the red aurorae becoming more common like this past week despite the relatively low magnitude events observed.
It's astonishing how much we have left to learn about the dynamics of our solar system alone. I still think that despite the weakening of the magnetosphere, it still is mostly a game of luck with the flare itself. A large and powerful flare aimed directly at earth is a very bad day.

Thank you for that reply. This is a great conversation and it's interesting to read the different information.

With imaging I get how you can beat seeing in photography with lucky imaging.
How would a using filter change the effects of seeing?
Isn't the only reason seeing effects bigger scopes is because you have the resolution to magnify enough to see the bad seeing?

Earth has been hit by even more impacts than Mars has but because Earth has a thick atmosphere and strong weather systems the impact craters get weathered down until they are no longer visible or the the objects burn up in the atmosphere before hitting the ground.

A major factor in the strength of a geomagnetic storm is the strength of the Earth's magnetic field. It's been dropping since we first started measuring it and has fallen by at least 20%. As it continues to drop weaker CMEs will cause stronger storms and strong CMEs that the field would usually just shrug off now have a larger chance to cause damage to our electrical infrastructure.

It’s a good thing the whalers didn’t discover this first, or it would have a wildly different name.

Just heat up those poles and after some time you will have green house gas with thick atmosphere, it will bring back the rain and regulate the temperature

What costly measures are used to eliminate the effects of bad seeing?

I think my home planet is in there, somewhere.
Beam me up, Snotty.

Well, there's plenty of pictures of it on the internet, so enjoy ;)

Do we/will we have satellites orbiting mars for pictures? Id like to see the near street view of Mars

Honestly every time I see images like this I am blown away at how amazing and huge our galaxy is. It’s like an ecosystem of cosmic bodies instead of animals. Beautiful.
