Earlier this month, I traveled by air for the first time during the pandemic.
Even though I'm "healthy" by all accounts, I live with at least one highly vulnerable person, and it's very important to me to not bring #covid into my house.
Here's what I've learned since. 🧵

First: if you're someone who cares about #covid safety, you will wear a mask every time you're indoors, period.
But not all masks are equal, and not all indoor environments are equally safe/dangerous.

For most indoor spaces, wearing a well-fitting, NIOSH certified N95 mask is totally sufficient.

Follow this thread for live-tweets of the first plenary of #AAS240 — "Phosphine in the Atmosphere of Venus" by Jane Greaves
Mariner 2 / Venera 14 showed an inhospitable surface on Venus — 900 degrees Fahrenheit! thought to be a "runaway greenhouse" 
but -- some people think microorganisms (remnants of a biosphere on the surface) could have taken refuge in the clouds of Venus after the surface was "baked"
