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! 🔭🧪

Being this cute is tiring work! Newborn baby Nsimba settled down for an impromptu calfnap, with 360-degree supervision from his mother and a surplus of nannies. Read about our latest grandbaby — a birth announcement-turned-kidnapping for the books! Full story here: t.co/fh1zSFQVc1

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.
Mass killings reported in militia attack on Darfur hospital in Sudan
The World Health Organization says the attack this week involved gunmen striking in several waves, abducting doctors and nurses, gunning down staff, patients and people sheltering there.

“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!”

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.
