Lets sum up Astronomy Announcements shall we with one sentence from them all:
"its very rare  ____"

Yah bra we get it.  Something new every day. Gods creation is awesome.

Keep up the good work and making it relatable to us. Salamat.
Why don't you delete this post and keep your garbage on one of the threads you started.

Some of enjoy this thread.

Thanks for the link Tom...

Is this the beginning of spaghettification?  The ramifications of dipping a toe across the event horizon I can picture in my mind.

Sort of, but spaghettification usually refers to a solid object whereas in this case, it's a cloud of gas and dust. Since the cloud isn't uniform, i.e., it has areas that are denser than others, it's more likely to fragment first. Ultimately, yes, the cloud's material will form a long stream, but probably not spaghettification in its true sense.

PS. There's a more layperson-orientated article here about the X7 cloud and the Keck observations:

Just as a quick follow-up, here's another article about Keck's observations of X7. In this article, they actually use the term "spaghettifying" although it's a pretty loose use of the word. It has some good images though and a short artist's rendering of what will likely happen to the cloud.

This should get people interested here.

"Astrophysicists on Maunakea discover galaxy protocluster COSTCO-1 with surprisingly hot gas"

https://bigislandnow.com/2023/03/16/astr...y-hot-gas/

"Observed when the universe was 11 billion years younger, COSTCO-I dates back to a time when the gas that filled most of the space outside of visible galaxies, called the intergalactic medium, was significantly cooler."

I suggest that even if you have enough gas, most of the items have already gone past their sell-by date.

Hot gas all around it, but cooler gas once you get there? If only they found a twin protocluster closer to us, we could investigate it more often...

When interglactic medium doesn't cover it, COSTCO-1 had protocluster size. Even 11 billion years ago.

We need a COSTCO-1 in Hilo.
Certainty will be the death of us.
