Space and Astronomy in general

Is there a good reliable and digestible source of info for the new JWST findings?
I am seeing all sorts of wild and questionable stuff in youtube. It seems the conspiracy nuts have adopted JWST as a new focal point. I'd like to know if JWST actually has uncovered evidence that the big bang theory is off the mark

No, it has not. The original article came from a proponent of the long-debunked "Electric Universe" hypothesis, and was simply grabbed at face value by "sCiENce!" websites, for clicks. Then more serious journos analyzed it, giving it even more credence.

This article is a really good look at the fake controversy that has erupted.

All findings? Not sure maybe the NASA JWST site.

But that big bang stuff was debunked immediately from articles I saw

Well, the other click bait that is going around is stuff like JWST found a "Schroedinger's" galaxy.
I guess I'm just really upset that people have to ruin a good thing. Nothing is safe from misinformation

"tHIs ChanGES eVEryThUnG" every 9 out of 10 youtube video title after JWST's first batch of pics

"WE WERE WRONG!!!!!!!"
"THE TRUTH REVEALED!"
"WHAT NASA DOESN'TWANT YOU TO KNOW AND MORE!"

Yeah, there’s a lot going on with this. The claims if Milky Way-mass galaxies in the early universe have turned out to be clearly wrong. And not only are folks fooled by closer, very dusty galaxies, but the calibrations used to do all of this were still ground estimates. Many of the instruments turned out to be more sensitive than expected, and that hadn’t been accounted for in many studies.

The good news is that when we start producing spectra en masse, this problem will get sorted out easily.

I’m gonna put this here again. The sky isn’t falling. The Big Bang is fine. A lot of these claims are based on results that are still open to plenty of questions. And of the claims of galaxies that are too big for when we see them — we don’t actually know their redshifts well yet (when exactly they were formed). Even if they are abundant in the very early universe, the people who construct computer simulations of galaxy growth say it’s not really an issue. So any tension is a bit overstated.

There was a mad rush to be one of the first publications. Now we wait for the rush to have a robust, thorough result. Much of that will require new observations that will trickle in over time.

Boy, I can't believe that I got home from work tonight and no one has posted about NASA/JPL punching an asteroid in the face.

If you're impatient, jump to about 1:13:00 in the video above.

The like button, I am smashing it and it only goes up 1! (although I guess for a math joke, it is true both whether 1 factorial or 1 exclamation)

How long until we can confirm that we killed it?

I think we probably just made it mad.

It will be weeks before we get an idea of how much the orbit was changed.

There will be some pictures from ground-based telescopes, and also from LICIACube which was on the scene.

The ESA Hera mission will be there in a few years, too.

I watched. But then I went outside to look at Jupiter, closest I will ever see it. 100+ years until it's this close again. Unless some miracle of tech happens I don't think I'm going to make it to 150

Did we at least use a hollow-point satellite?

Jupiter passed Europe around 9:30 PM, but it was pouring rain the entire evening and night. I was looking forward waking up our 7 year old to watch the Big One together, but no such luck

ELI5: does this mean the moment has passed completely? Or is Jupiter still visible today and the coming days, just not as clear and close by as last night?

Planets don't move very fast, it will still be just as prominent in the night sky for at least a couple of months. It was marginally closer than usual last night but the difference is so small you would never notice it with the naked eye.

Thanks! We are new at this, but we bought a nice telescope for our daughter's 7th birthday. We've been ogling the moon mostly, but as soon as the clouds part we're going for the planets

Yeah it's been very bright for the last month or so. I've seen it a lot. Just made a point to look last night specifically. Will still look for for a while. And being visible just after sunset here is nice, can show the kids before bed

Another angle of asteroid impact last night

DART successful. Orbit changed by 32 minutes.

Just saw a tweet from NASA not a full article yet.

Edit: Article with images

God bless those oil rig workers for their sacrifice!

Bruce Willis's career was pretty much in the toilet anyways ;P

Those guys deserve a Montgomery Burns Award!

A couple of really striking images crossed my path lately.

FIrst, Jupiter in Ganymede's Shadow:

After that, this is what Lucy saw during her recent Earth flyby:

Is that false color for Jupiter? If not, that is a stunning photo!

The image is from JunoCam, which is supposed to operate in an RGB mode or an IR mode. So I think that image is close to "real".

Artemis + Orion launch is a few hours away (maybe), heading to the far side of the moon and back.

Bit late but screw it I stayed awake. 7 more minutes.
