MadMadBunny, 2 tygodnie temu w Webb telescope just snapped direct image of worlds many light-years away

It’s incredible!!

LostXOR, 2 tygodnie temu w Webb telescope just snapped direct image of worlds many light-years away

That's really awesome! I'm impressed that JWST's coronagraph was able to block out the star's light so completely.

Incredible! These are like the old Hubble shots of galaxies by how blurry they are - but these are freaking planets!!!!

The next thing after Webb is gonna be ridiculous.

Those will like be the Nancy Grace Roman and LUVOIR space telescopes.

Olgratin_Magmatoe, 2 tygodnie temu

Yeah, that 2039 date projection for LUVOIR is awful. Especially considering that it will almost certainly be pushed back a few years.

I’d love to see something that big happen though.

threelonmusketeers, 2 tygodnie temu (edited 1 tydzień temu)

Well, if JWST was worth the wait, I’m sure LUVOIR would be as well.

But yeah, I’m impatient too :)

I’m so fucking pumped about the Roman telescope

I’ve taken photos of Jupiter that are blurrier than this 😫

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.

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.

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.

Klanky, 2 tygodnie temu w Stargazing Saturdays 2025-03-15

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

crapwittyname, 2 tygodnie temu w Asteroid 2024 YR4 now has a 1.94% chance to hit the Moon (according to my own calculations)

Nice work! Does the uncertainty come from error bars in the observed trajectory? I would’ve thought an asteroid’s path is pretty easy to pinpoint with enough information.

LostXOR, 2 tygodnie temu

Yep, even the best telescopes have a bit of inaccuracy in their measurements, and we haven't been tracking it for long enough to determine its orbit with enough precision to know its exact trajectory.

threelonmusketeers, 2 tygodnie temu w Asteroid 2024 YR4 now has a 1.94% chance to hit the Moon (according to my own calculations)

Do we know if the Moon will be in the correct phase in it’s orbit when 2024 YR4 comes by? I didn’t notice a term to account for that, but I’m not too familiar with Desmos.

LostXOR, 2 tygodnie temu

The calculations for the close approach data I'm using to calculate the probability already take the Moon's orbit into account.

Nooo not the moon, it didn’t do nothing to no one. Come back YR4, we still have some lovely cities you could obliterate.
