Vera C. Rubin Observatory Discovers 11,000 Asteroids In Just Weeks, And This Is Only The Start A new data release reveals over 11,000 new asteroids, signaling a dramatic shift in how scientists explore and protect our solar system.

Vera Rubin Observatory discovered 11,000+ asteroids in six weeks—including 33 near-Earth objects and 380 trans-Neptunian worlds. We've only identified ~40% of mid-sized NEOs. The ones we haven't found could be the ones that find us. Rubin changes that.

Planetary Defense: We deflect asteroids, but we can't find them. 15.000 asteroidi possono distruggere una città e non sappiamo dove sono. La difesa planetaria esiste sulla carta: nella realtà, meno.

NASA proved it can deflect an asteroid. Then it scrapped the only spacecraft that could do it. Now it admits 15,000 city-killer rocks are out there, untracked. The telescope to find them costs less than an aircraft carrier.

Hunting for the Lunar Debris Hiding Near Earth The Moon has a long history of being smacked by large rocks. Its pock-marked, cratered surface is evidence of that. Scientists expect that, as part of those impacts, some debris would be scattered into space - and that we should be able to track it down. But so far, there have been startlingly few discoveries of these Lunar-origin Asteroids (LOAs) despite their theoretical abundance. A new paper from Yixuan Wu and their colleagues at Tsinghua University explains why - and how the Vera Rubin Observatory might help with finding them.

Asteroid impact simulation reveals the hidden strength of space rocks Physicists at the University of Oxford have contributed to a new study which has found that iron-rich asteroids can tolerate far more energy than previously thought without breaking apart—a breakthrough with direct implications for planetary defense strategies. The findings have been published in Nature Communications.
