6,000 #exoplanets have been found to date, but ZERO of them are Earth-like planets around Sun-like stars! Why is that? Do any exist? Or is it just hard? ☀️🌍🔭

This is the best best best fact I've learned all month and I watched a LOT of videos about dinosaurs and European royalty.
It's staggering.

My 10yo son (from California) and I (from Queensland) are signed up for a Turkey Trot in Cleveland this morning. Currently there is a Severe Weather warning, for wind and lake effect snow. It’s not supposed to snow until this afternoon, but it’s gusty (33F, feels like 16F). Advice?!? Just bundle up?

Okay I went and looked in the acknowledgments and it sounds like he talked to a few astronomers, including @andyhowell.bsky.social, so presumably THEY used the NASA Exoplanet Archive and Andy Weir wasn’t messing about on the website himself. 😅😭
I am (finally) reading Project Hail Mary and I NEED TO KNOW if Andy Weir visited the NASA Exoplanet Archive during his research phase. 👀

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

One time my husband and I were asked to bring 'a dessert' to his family's Thanksgiving that we were driving six hours to attend. We made a box brownie mix the night before and brought it in the car with us that day.
Turns out it was THE dessert for 20+ people.

Ohhh I see. They couldn't let Democrats get the credit for the extension, so they waited them out, re-opened the government, *then* extended the subsidies so Trump could get the credit.
