NASA’s Perseverance Rover Scientists Find Intriguing Mars Rock
The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed.

Haemus Mons is a mountain located near Io’s south pole and, in this image, lies near the terminator in this image from Voyager 1 on March 7, 1979. Its base spans about 200 by 100 kilometers.

Holy shit.
This is 3I/ATLAS—the interstellar comet recently discovered passing through the Solar System.
You're looking at something that didn't start out here.
It came from another star.
And, at about 7 billion years old, it was already ancient when our Sun was born.

The NASA/ESA/CSA James Webb Space Telescope has found evidence of a cold, Saturn-mass planet around the star TWA 7, seemingly sculpting its disc of debris!
If confirmed, this would be Webb’s first direct image discovery of a planet.

See that orange blob?
That's probably a Saturn-mass planet orbiting its parent star, the light from which has been blocked.
A whole other planet in a system only a few million years old, possibly still undergoing formation and developing its own ring and satellite system.
111 lightyears away.

Rather hilariously, Saturn just got up to 128 new moons (thanks to some careful telescopic observations), bringing its total to…274? That’s just an absurd number of moons.
