What's the deal with the forked diffraction spikes on the bright star? I don't think I've seen that in any other images.

We would be living on Tatooine basically (assuming some of us will live).

I don’t have much to say but I like your comment. I didn’t know Mercury has, maybe in some part, a liquid core. Been writing some stuff about Mercury as usual. I found it fascinating in a sense for storytelling wise, a leftover planet. Anyways writing is a whole other tangent lol. Mercury mining while being landlocked by Venus due to technology not advanced enough to drive past planets. I need more world building lol.

So what your saying is that it’s possible.

After killing us all and starting over (due to all sorts of radiation and gravity issues pulling and hitting the planet) then maybe?

There’s so many fucking galaxies out there man. Existential dread in a frame.

My understanding is that the problem for Mars and Mercury was that they aren't massive enough to keep their cores hot, so as the cores cooled their planetary dynamos slowed and the magnetospheres dissipated.

Most people just refer it as the Roman Space Telescope

Most people do already call it the aromas space telescope- that’s what all their merch says at least

please don’t try to get yourself a personal magnetosphere. It’s not worth it.
Jokes aside, I believe we’re not really sure how and why intrinsic magnetospheres show up on Earth and Mercury but not Venus and Mars (which have induced ones which block solar wind better instead). Mercury, Earth, and Mars are all known to have liquid core, but it seems Mars’ core isn’t convecting and thus no dynamo.

The atmosphere blocks radiation well enough on its own, thanks. An intrinsic magnetosphere doesn’t really protect the atmosphere either.

>Let iteration and selection handle it for you.
Yep, computers have been a boon in that respect.
Reminds me of an old Sci-Fi trope of alien ships being 'grown', not constructed.

Things change so fast I don't think you'll get bored. Life and technology and science is nothing like when I was a kid. Not that long ago we didn't have electricity.
If we are mentally able to keep adapting and learning I don't think I would get bored. Even our imagination of the future is way off.
If we keep fucking around with wars and greed killing our planet it may not be so fun.

Take a planet with a molten center and smash another planet, preferably with water on it into it.. as the internet has led me to believe..

You should read Borges’ ‘The Immortal.’ An amazing short story that seeks to answer this very question.

Your comment makes me wonder about something practical. If we did live eternally, how long would it be before we were dissatisfied with life in that we run out of interesting things. Could one live 500 years and remain interested in life on Earth? Totally off topic, but related to the scope of time.

A twin G class solar system is kinda like the Alpha/Beta Centauri system. There, two main suns orbit each other with a third red dwarf, and everything else orbits them. Depending on the inter-solar distance and barycenter, planets in such systems may follow peculiar orbits. For example, a rocky planet like ours may orbit in and out of the Habitable Zone, so hard for life to arise.
Make your own star system and play with it.
Click Lab and then the pull down for binary star, planet.
Turn on Path to see planet's wild orbits in a binary star system. There are other systems too.

The dynamo effect. Theoretically if you take a bunch of metallic elements and make them really hot and spinny you get a big ole magnetic field.

for the beneficial effects of a magnetosphere shielding terrestrial civilization. We wouldn't necessarily have to be forerunners to achieve this.

Ultrasonic testing is probably the most common method of non intrusive/destructive scanning.
