Minarble, w Webb telescope just snapped direct image of worlds many light-years away

You are looking at actual images of planets from another solar system… I just think that’s neat!

That’s a trip. I keep having that moment with the JWST where I think okay, now I get the hype and then it surprises me again.

espentan,

I, too, think that is neat!

Who knows, maybe on one of them there are people, and maybe they put the dumbest one of them in charge, and now everyone is having a terrible time.

XeroxCool,

I saw the image embedded in one of the comments here before hut somehow didn’t realize the gravity of it until this thread

to replace astronauts stranded for 9 months

They were never considered stranded, except maybe for the few days between Starliner’s empty return and the Crew-9 Dragon’s arrival. Certainly not for 9 months.

This also isn’t really relevant to astronomy.

Yo dawg, I heard you like galaxies…

Report: ended up scuttling the plans. I’ve had a few late nights in a row, and the transparency was bad enough to give me a good excuse to sleep instead. We’ll get them next time, team.

Man I need to get my scope out again. It’s been years. Maybe one of these days…

mysticpickle,

Some asses are so THICC they just collapse into themselves in an explosion of seductive destruction that can be seen light years away

Unfortunately we’ll never get to visit them in person if Prostetnic Vogon Jeltz has anything to say about it:

We are about to jump into hyperspace for the journey to Barnard’s Star. On arrival we will stay in dock for a seventy-two-hour refit, and no one’s to leave the ship during that time. I repeat, all planet leave is canceled. I’ve just had an unhappy love affair, so I don’t see why anybody else should have a good time.

FundMECFSResearch, w Confirmed at Last: Barnard's Star Hosts Four Tiny Planets

Just 6 light-years away, Barnard’s Star is a well-studied 10-billion-year-old M dwarf with a mass of 0.16 solar mass. Finding exoplanets around Barnard’s Star has been something of a white whale for astronomers for more than half a century; starting in the 1960s, researchers have claimed to have spotted various planets around Barnard’s Star, from distant Jupiter-mass companions to close-in super-Earths. Each of these claims has been refuted.

Now, the white whale appears to have been caught at last. Just last November, researchers reported the discovery of a planet orbiting Barnard’s Star with a period of 3.154 days. The data hinted at the presence of three other planets, but these candidates could not be confirmed. In a new research article published today, Ritvik Basant (University of Chicago) and collaborators leveraged years of data to confirm that Barnard’s Star hosts not just one, but four planets.

SplashJackson,

Good summary, but to everyone else reading this, it’s really worth it to read the article. It’s short and yet, frankly, fascinating. It discusses the methods used to identify the exoplanets and their orbital periods.

“Did you bring enough to share with the whole class?”

the class:

pennomi, w Confirmed at Last: Barnard's Star Hosts Four Tiny Planets

These planets are in remarkably close quarters, with periods of just 2.34, 3.15, 4.12, and 6.74 days.

Speedy little guys

very_well_lost,

The furthest of the four is estimated to have an orbital radius of about 0.03 AU. That’s 1/10th the size of Mercury’s orbit around the sun!

veroxii,

At least it’s a dry heat.

muhyb,

That’s a fuel scooping range.

Warning, temperature critical.
