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! 🔭🧪

Asteroid 2022 RD₂ may become a mini-moon not once, but three times in 2043–2044. This may not exactly look like an orbit, But during each capture, if the Sun suddenly vanished, RD₂ would remain gravitationally bound to Earth indefinitely. iopscience.iop.org/article/10.3...

Difficult to overstate how profound a failure DOGE was. Spending in FY2025 was not only than in FY2024 – but higher than it was projected to be when Trump first took office.*

The little bit of spending DOGE cut has already killed hundreds of thousands and will eventually lead to millions of deaths.
Bye bye, “DOGE”.

It no longer exists as a “centralized entity”, according to the Office of Personnel Management.

Couldn't make out #Saturn's rings at all just now through my telescope (admittedly from a light-polluted vantage point). We are now at the secondary "almost ring-plane crossing" due to Earth's orbit, and we'll have #JWST taking some infrared spectra of Saturn's southern spring next week.. exciting!
#Saturn's simulated appearance from Earth from Jan'25 to Dec'26, showing the changing perspective of the rings as the gas giant moves into southern spring. SkySafari doesn't render the ring shadows, & Saturn is out of view on the other side of the Sun for the ring-plane crossing tomorrow, Mar 23rd.
