Spaceweather.com has up to date info on CMEs and solar wind velocity and density. Keeps track of sunspots and which ones might erupt and warns when they do. A recent CME knocked a bunch of Starlink satellites out of commission. Big CMEs sometimes precede big earthquakes

NASA’s Webb Finds Carbon Source on Surface of Jupiter’s Moon Europa

 

https://www.nasa.gov/feature/goddard/2023/nasa-s-webb-finds-carbon-source-on-surface-of-jupiter-s-moon-europa

 

'...“We now think that we have observational evidence that the carbon we see on Europa’s surface came from the ocean. That's not a trivial thing. Carbon is a biologically essential element,” added Samantha Trumbo of Cornell University in Ithaca, New York, lead author of the second paper analyzing these data...'

Seems like the gas giants have some interesting moons. Isn't Io the one with the underground oceans or something? I know Titan is the one with an atmosphere so thick, humans could fly if they had wings strapped on.

Under thick ice, yes.

We sure there's not a Big Black Monolith floating in orbit?

 

 

 

I dunno but have you been seeing all the stories about other planets in our solar system lately?

 

Reminds me of the planetX / Nibiru, anicient Sumerian or book of Enoch stuff. 

 

Fun.

Io is the one with high volcanic activity because of the strong tidal pull from Jupiter.  No oceans thought to be on that one.  Europe is the one that they have found evidence of water (in the form of jets).  Again, tidal activity is key to heating the interior, which heats the water, which gets ejected at times.  Europa is the one where they think life could exist.

Nope. That's Europa....and Saturn's moon, Eceladus.

 

Io, in fact, is the most geologically active body in the solar system. It's Jupiter's closest moon and because of that it's constantly subject to immense tidal forces....it's pretty much covered in volcanoes....

Thanks Rup.

I thought that he was asking about Eupropa, didn't even register lo in his post.

NASA spacecraft delivering biggest sample yet from an asteroid

 

Planet Earth is about to receive a special delivery — the biggest sample yet from an asteroid.

 

A NASA spacecraft will fly by Earth on Sunday and drop off what is expected to be at least a cupful of rubble it grabbed from the asteroid Bennu, closing out a seven-year quest.

 

The sample capsule will parachute into the Utah desert as its mothership, the Osiris-Rex spacecraft, zooms off for an encounter with another asteroid.

This is about Larry Niven's The Integral Trees. He got the idea from the torus of plasma that exists around Jupiter.

 

The story occurs around the fictional neutron star Levoy's Star (abbreviated "Voy"). The gas giant Goldblatt's World (abbreviated "Gold") orbits this star just outside its Roche limit and therefore its gravity is insufficient to keep its atmosphere, which is pulled loose into an independent orbit around Voy and forms a ring that is known as a gas torus. The gas torus is huge—one million kilometers thick—but most of it is too thin to be habitable. The central part of the Gas Torus, where the air is thicker, is known as the Smoke Ring. The Smoke Ring supports a wide variety of life.
