Sort of self-explanatory but remarkable because the pic was taken by a telescope in Chile. If all goes well and the James Webb Space Telescope begins operations at Lagrange Point 2, we’re likely to be able to see the atmospheres of exoplanets nearby. We should be able to determine if they’re life-supporting very soon.

Our moon is considered to be critical in the origin and maintenance of life on earth because of its role in stabilizing the planet’s tilt. This gives us distinct and predictable seasons. We may soon know how prevalent moons are around earth-sized planets.

Astronomers have discovered the first disk surrounding a planet outside the solar system.
The impressive circumplanetary disk is about 500 times larger than Saturn's rings and encircles a Jupiter-like planet dubbed PDS 70c. Scientists have seen plenty of disks surrounding distant stars, and moon-forming disks around planets like this have been suspected before, but this is the first time such a system has been definitively identified, according to the researchers.

Can't wait. I'm still not sure why the calibration missions are on Jupiter for the JWST, other than it eventually becoming a brown dwarf.

"It will be a really challenging experiment," said de Pater. "Jupiter is so bright, and Webb's instruments are so sensitive, that observing both the bright planet and its fainter rings and moons will be an excellent test of how to get the most out of Webb's innovative technology."

It's only alien if your not from the neighborhood. ... ya peeping Tom.

What were the alternatives?

Don’t know. Maybe Uranus and its rings, or Neptune. Needed something with adjoining bright and dim objects.apparently.

That's amazing resolution
And it’s from a ground-based scope. The JWSt and Europe’s Extremely Large Telescope, also to be located in Chile, should give us info about habitable exoplanets within the next two years.

Hopefully it works out. Ephemeral time and encapsulated time don't always work together. I was worried about the heat from Jupiter, but I didn't design the telescope. Surely the mission wasn't changed because of the name Uranus.

While most of its over my head, I love watching vids on this stuff. I usually get lost in the mathematics.
