If galaxies could talk…

We come with receipts🧾

Tidal tails are cosmic “receipts” of galactic drama, showing who collided with whom. Rubin's camera is sharp enough to catch wind of even the faintest intergalactic tea.

No need to worry about "pics or it didn't happen" with Rubin keeping a close eye 😎 🔭🧪

A sprawling field of galaxies fills the deep black of space, dotted with glowing stars and colorful smudges of light. Near the top, a smooth golden elliptical galaxy glows like polished stone, linked by delicate, taffy-like streams of stars to nearby galaxies below—evidence of ancient cosmic collisions.

Hey, so...Covid rates have gotten real high. Maybe change your behavior to fit this new risk profile? Stop eating indoors at restaurants, mask on mass transit, that kind of thing?

A graph of Covid rates. It's more complex than can be described here, but the important bit is that the rates have gone up a lot since late July, nearly to the heights of last winter.

Our new study finds that the upper atmosphere is becoming more sheared and less stratified because of climate change. Both these changes are making the atmosphere less stable and more conducive to turbulence.

University of Reading research shows that clear-air turbulence, which is invisible to aircraft, is set to get worse.

This is a shocking executive order that undermines the very idea of open inquiry. It turns federal grants into dispensations, subject to arbitrary and capricious withdrawal should the recipient say or believe the wrong things.

Actually, the best protection is to *combine* vaccines with N95-wearing, indoor space ventilation and indoor air filtration.

All of those things will reduce your risk of developing Long COVID, which can damage your heart, brain and other organs.

COVID-19 is circulating in California. Stay up to date on your COVID-19 vaccine. It is the best way to protect yourself from serious illness.
