I have been busy lately... Here is an article that explains what I did (with a few pictures I took on the way)

NASA Flights Study Cosmic Ray Effects for Air, Future Space Travelers - NASA

Recent airborne science flights to Greenland are improving NASA’s understanding of space weather by measuring radiation exposure to air travelers and

YES, GOD, I AM SO FUCKING PSYCHED FOR THIS:

Best look yet at Comet 3I/ATLAS, the interstellar visitor that is now racing through our solar system.

The comet is currently 600 million kilometers from the Sun, between Jupiter & the asteroid belt. As it moves closer, the images will inevitably get better.

Microsoft marketing: “Your data stays in Europe.”

Microsoft’s Legal Director (under oath, in French Parliament): “No, I cannot guarantee that.”

Still think Microsoft Teams is a sovereign solution?

An old failed Venus lander will re-enter from earth orbit next month, and it could land anywhere between 52 degrees north and south. Which covers basically all population in the southern hemisphere and a large majority in the north, leaving out the Baltics, Nordics, and Alaska.

It weighs a thousand pounds and is expected to reach the ground intact. Previous debris from the launch landed in New Zealand.

#astrobiology thread time!

A paper came out a few weeks ago about "habitability". Specifically, the habitability of Saturn's moon Titan.

We (am one of the co-authors) found that Titan's chemistry could support the equivalent biomass of a small dog.

Is that....bad?
(And what does "habitability" mean anyway?)

Here is the press release from the University of Arizona: https://news.arizona.edu/news/saturns-moon-titan-could-harbor-life-only-tiny-amount-study-finds

(Next post will have link to full paper)

Saturn's moon Titan could harbor life, but only a tiny amount, study finds | University of Arizona News

Despite its rich inventory of organic molecules, Saturn's largest moon may be able to support only a minuscule amount of biomass, if life exists there.

I didn't know

When I learned about the holocaust as teenager in Germany, many people from the Nazi era were still alive and lived all around me. Being the curious person I always was, I asked them about what happened and their role in it.

"I didn't know" was the boilerplate answer. And as they were relatives and friends, I believed them at first.

Then in 1981 we got a new teacher for history and he exposed the lie. Or more precise: he got us exposing those lies.
