Captured today in broad daylight from San Francisco using SkyViewer on app.skymapper.io. Dark nights are back in Finland! I used one of our Finnish telescopes for a 10-min observation of the Fireworks Galaxy (NGC 6946), 25 million light-years away. Astronomy without borders!

Great news for astronomy! NASA selected PRIMA, a far-infrared space telescope, as the first Probe Explorer mission. PRIMA will see through cosmic dust to study how planets form, galaxies evolve, and water and other key ingredients for planets emerge. Launch: 2033! gagadget.com/en/727314-na...

The new Probe Explorer-class observatory will scan the universe for the origins of water, planets, and black holes — filling a spectral gap untouched since Herschel.

Astronomy continues in Ukraine. Astronomers in Kyiv detected a new outburst of the cataclysmic variable Gaia20cnt with a Unistellar eVscope, triggering follow-up with their 70-cm AZT-8 telescope. Science continues despite the war. www.astronomerstelegram.org?read=18059

If you can’t trust the data, you can’t trust the science. As AI makes fake observations easier to create, provenance matters more than ever. At Avalanche Summit NYC, our CEO @allplanets.bsky.social explained how blockchain can help make astronomical data verifiable from the moment it’s captured.
