15 day orbit, 170 day planetary rotation, that's an interesting one

Sucks for the amount of radiation ofc

Would be interesting to hypothesize of it being a larger mercury like planet than a earth like one

Please some more up to date astro-duders out there, is the James Webb currently capable of direct spectrography of exoplanets? We can do spectrography during the transit I am aware, but direct spectrography, is that possible? Specially when we are talking of an infrared telescope

Could be a non problem depending on the atmosphere

Always nice to have options on where to send the colony ships.

Followed by an ALM movement a hundred years later. Aliens will rise up complaining of how they were treated in the mines by no other than the earthling colonists.

That's sheer insanity. It's mind boggling that at that distance (and therefore footprint on the optical elements) you can directly resolve something even as small as 7x Jupiter.

Detected by the radial velocity method, measuring the parent star being pulled toward and away from us by a variation of at little as 2-3 meters per second! It always blows my mind that we can measure that.

Read up about the precision LIGO needs. Pretty mind boggling.
