James Webb Telescope Launch and updates

[Riddla]

The James Webb Space Telescope has caught a glimpse of the most distant star known in the universe.

The star, named Earendel, after a character in J.R.R. Tolkien's "Lord of the Rings" prequel "The Silmarillion," was discovered thanks to gravitational lensing in a Hubble Space Telescope deep field image. The star, whose light took 12.9 billion years to reach Earth, is so faint that it might be rather challenging to find it in the new James Webb Space Telescope image

James Webb Space Telescope glimpses Earendel, the most distant star known in the universe

The star's discovery by the Hubble Space Telescope was only announced earlier this year.

It could’ve been blown up by the Death Star 11.9 billion years ago, and we won’t know for another billion years.

Those numbers just sound like make-believe to me. Hard to grasp.

Think about this...

That pic has several galaxies in it...several

As in so many galaxies that it woukd look like the stars in our night sky...but they a galaxies...its ****in nuts man.

But...but...but...HOW did the James Webb MISS ALL of those UFOs??!!

Solar system to scale

Andromeda. Its traveling at 110km per second or 68 miles per second. Yet it will take roughly 4 billions years for it to collide with the milky way.

There are 963 different to-scale representations out there attempting to depict the vastness of our galaxy as compared to our piddly solar system. However, the other day I came across one that I could almost wrap my head around. If the Milky Way were reduced to the size of the continental U.S., our solar system would fit on your fingertip. Wild!

K2-18b is an exoplanet orbiting a red dwarf located 124 light years away. It is in the habitable zone. It receives as much star light as Earth.

It is a Hycean (hydrogen ocean) planet. James Webb has detected hints of DMS (dimethyl sulfide) which is only produced by life. Or it can also mean that it may be caused by a different phenomena that we are not aware of yet.

Holy shit that's huge
