Officially in our Operations era✨

NSF–DOE Rubin Observatory has concluded its Construction phase & entered Early Operations.

While day-to-day work continues, this milestone marks the home stretch of final fine-tuning ahead of the start of the ten-year LSST, just months away! 🔭🧪

Toad found a lantern in the attic. “Frog will see this light. I will show him the way out of the woods,” said Toad.

The Sun has produced four moderate (M-class) solar flares today. We expect solar activity to continue increasing for the next week or so, as busy regions on the Sun rotate to face Earth!

I know folks in the US find it hard to think about the world beyond your borders but there is an absolute horrific situation unfolding in Sudan, and people everywhere need to be aware of this, writing about this, and talking to their politicians about assisting.

“We must make a second try,” said Frog.

“Hurry!” said Frog. “We will run and catch it.”

“No!” shouted Toad. “I cannot do that.”

“Why not?” asked Frog.

“Because,” wailed Toad, “running after my list in not one of the things that I wrote on my list of things to do!”

These young, hot blue stars formed only about 100 million years ago. They are called The Pleiades! They are visible with the naked eye and are located around 440 light years away! #astronomy #universe #Astrophotography #star @kat-astro-bot.bsky.social

From trunk to tail, every inch of Amali is coated in Nature's own sunscreen and insect repellent: mineral-rich mud. Umani's unique volcanic springs produce this distinctively dark grey mud. The orphans take advantage of the protection it offers in this heat, wallowing to their hearts content.
