11,000 New Neighbours!
Following the great club lecture last week from the Vera C Rubin team:
Big news from the world of planetary defense and solar system science! The Vera C. Rubin Observatory has just released a massive haul of new discoveries from its early test runs—and the numbers are staggering.
Even before its full 10-year survey officially begins, the "discovery machine" in Chile has already:
✅ Identified over 11,000 brand-new asteroids.
✅ Tracked over 80,000 known asteroids (including many that were "lost" because we couldn't track their orbits accurately enough).
✅ Spotted 33 new Near-Earth Objects (NEOs)—don't worry, none are a threat!
✅ Found 380 Trans-Neptunian Objects (TNOs)—icy worlds at the very edge of our solar system.
Why this matters for us:
What used to take astronomers decades to find, the Rubin Observatory is now finding in a matter of months. It features the world's largest digital camera (3,200 megapixels!), and it's going to completely rewrite our map of the Solar System.

Can we observe these? 🔭
While these specific 11,000 new asteroids are currently very faint (detected by professional gear), this is a great time for club members to practice their asteroid hunting on the brighter "Main Belt" objects!
How to observe: Use an app like Stellarium or SkySafari to locate 4 Vesta or 1 Ceres. Vesta is often bright enough for a small telescope or even binoculars from a dark site.
The "Move" Test: To confirm you've found an asteroid, sketch or photograph a star field over two consecutive nights. The "star" that has changed position is your target!
Best Time: April is a great time for observing as the nights are still reasonably long. Look for asteroids when they are at "opposition" (opposite the sun in our sky) for maximum brightness.

Scientists at NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science, have submitted an unprecedented set of asteroid detections to the IAU Minor Planet Center, including hundreds of distant worlds beyond Nept...
