Did aliens watch 1950s nuclear tests? ‘Maybe,’ studies say
OK, it’s probably not aliens, but two new studies confirm 1950s sky flashes were real, reflective objects, and their appearance statistically correlated with nuclear tests.

I love symphonic metal/rock music, but somehow missed The Rock Orchestra until now (which started in 2020)! A rotating collective of musicians combining classical, rock and metal music with gothic visuals. This cover of Zombie by The Cranberries, with Erin Fox, is amazing. 😲

Had a dream last night that I was seeing live close-up video of 3I/ATLAS. It was a huge sphere with many little tubes or nozzles around its middle. They started emitting a lot of vapor or gas of some kind. And then a larger one shaped like a horn did the same thing. 🤷♂️😯

In regards to the exciting but still-potential discovery of evidence for ancient microbial life on #Mars, if I have to choose between random internet “experts” and the nearly 90 scientists listed in the peer-reviewed paper, I’m going to go with the scientists actually involved.

I really didn’t like what Charlie Kirk stood for. BUT, murdering him was not the answer! He now has a grieving wife and young kids. There’s way too much violence as it is in this world. I see some cheering his death and MAGA declaring “war.” This madness has to end, but I know it probably won’t.

The NASA Mars press briefing on Wednesday is about the same rock sampled in July 2024 with the “leopard spots” and “poppy seeds” markings on it. Those were identified as potential biosignatures, so the briefing on Wednesday will be an update on that apparently. 🤔😯
