This is truly a remarkable artifact.
Yes, it is Musk tweet, so normally I could not be less interested, but some people actually clicked and, omg.
In addition to the obvious, notable what he contributes to the discussion and that everyone else seems to totally ignore him.
Perhaps he needs to be hit with a return to office mandate.

Re: Outer Space Thread
This sounds pretty amazing. I hope it's actually feasible!

Heads up... in 7 years... maybe...
NASA spotted a big asteroid that may hit Earth — what you should know
It's actually good news that NASA spotted a sizable asteroid with a (small) chance of hitting Earth in 2032. It means our asteroid-sleuthing telescopes are working. "These things come through on a regular basis," Jason Steffen, an astronomer at the University of Nevada, Las Vegas, told Mashable. "The fact that we're seeing something around a decade into the future shows the improved technology that's been deployed to watch for these asteroids."
The Asteroid Terrestrial-impact Last Alert System — a global network of telescopes funded by NASA to find Earth-threatening objects — spotted the asteroid 2024 YR4 in December 2024. Early observations of the asteroid's behavior and trajectory show it has a 1.4 percent chance of an Earth impact in the year 2032 (as of Jan. 30, 2025). The number you might not hear is the asteroid also has a 98.6 percent chance of missing our planet.
The impact prediction will change because astronomers don't yet have an accurate enough grasp of the asteroid's characteristics nor location. "If you want to make predictions about where it'll be in the future, you have to know its location conditions very well," explained Steffen. "A few meters off is a lot."

WHOA

Sooo freaking cool.
https://science.nasa.gov/missions/hubbl ... ine-rings/

LEDA 1313424, aptly nicknamed the Bullseye, is two and a half times the size of our Milky Way and has nine rings — six more than any other known galaxy. High-resolution imagery from NASA’s Hubble Space Telescope confirmed eight rings, and data from the W. M. Keck Observatory in Hawaii confirmed a ninth. Hubble and Keck also confirmed which galaxy dove through the Bullseye, creating these rings: the blue dwarf galaxy that sits to its immediate center-left.

This illustration compares the size of our own Milky Way galaxy to gargantuan galaxy LEDA 1313424, nicknamed the Bullseye. The Milky Way is about 100,000 light-years in diameter, and the Bullseye is almost two-and-a-half times larger, at 250,000 light-years across.

The article contains high res versions of the images I posted, plus some really cool info about the physics confirmed with this find (how the blue dwarf affected the larger galaxy by passing through it.NASA’s Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an “arrow” — a far smaller blue dwarf galaxy — shot through its heart. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using data from the W. M. Keck Observatory in Hawaii. Previous observations of other galaxies show a maximum of two or three rings.
“This was a serendipitous discovery,” said Imad Pasha, the lead researcher and a doctoral student at Yale University in New Haven, Connecticut. “I was looking at a ground-based imaging survey and when I saw a galaxy with several clear rings, I was immediately drawn to it. I had to stop to investigate it.” The team later nicknamed the galaxy the “Bullseye.”
Sooo freaking cool.
