Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years - Air Quality, Atmosphere & Health Air Quality, Atmosphere & Health - Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposure...

CO2 is now affecting the body chemistry of humans

If the current levels of emissions are maintained, we could be facing potentially toxic atmospheric compositions within 50 years

THIS IS STAGGERING AND DEVASTATING NEWS

Ok I promise this is the last picture of my comet that I'll post but I think this one is my favorite. Image by Beáta Ujvárosi.

This Comet Stopped Spinning. Then It Started Rotating Backward.

"One explanation might be that some like Comet 41P have jets that make them spin faster and faster until they are 'blown to bits by their own spin,' Dr. Jewitt said." #TheAstronomicalJournal Read more in this gift article www.nytimes.com/2026/02/11/s...

You can't... repeal... a scientific finding. At that point it's just called lying about it.

Congrats to @wierzchos.bsky.social on this beauty! C/2024 E1 (Wierzchoś) is putting on a show for southern hemisphere observers right now.

Oh yeah definitely

I guess I was referring to the holofit. Thanks!

Omg what software are you using on your bike?

Walk carefully! Drive carefully

I’ll never forget learning some pretty remarkable things about 29P’s (SW1) orbit from Uwe and if we go really far back I changed the filter wheel for him in the pitch dark during an observing run while a grad student.

Thanks for letting us know, Mark.

This is a grad school flashback thread

Thinking of you ~hugs~

Oh Kat, I’m so sorry you have lost her. Having gone through something similar recently I’m also very glad you were able to be with her.

Howdy neighbor! Lovely neighborhood. I’ve been there several times.

Perfect! Which lake is that

By port, I meant customs. I’m not an expert but I have seen a map of their range and it’s substantial
