UN‑Endorsed Asteroid Network Launches 3I/ATLAS Exercise as Images Reveal 5‑Million‑Kilometer Tail; Avi Loeb Flags Jet Anomaly Cristina Gomez reports that the UN‑endorsed International Asteroid Warning Network has begun an observing exercise for interstellar object 3I/ATLAS, coinciding with new images showing an estimated 5‑million‑kilometer tail and a tightly collimated anti‑tail. The update highlights Professor Avi Loeb’s “12th anomaly” regarding the object’s jets, outlines upcoming Earth and Jupiter approach milestones, and notes planned observations by NASA and ESA assets.

UN-endorsed IAWN begins observations of interstellar 3I/ATLAS as images reveal a 5-million-km tail and tight anti-tail. Avi Loeb flags a jet anomaly; NASA and ESA plan follow-ups ahead of Earth and Jupiter approaches. #3IATLAS #AsteroidWatch #Astronomy

The Mysterious Interstellar Object May Have Just Exploded "This would mean that 3I/ATLAS exploded at perihelion and we are witnessing the resulting fireworks."

3I/ATLAS lost some weight.

The parent bodies of these threatening #asteroids help us better understand the gravitational pathways that dislodge them from the main belt and send them into the inner #SolarSystem.

This knowledge is vital for helping us defend our planet from future worrisome #SpaceRocks.

From asteroid mining to space rustling—what do we do when an asteroid threatens Earth? Asteroids colliding with Earth might seem farfetched, but the planetary threat is real. Just this year news broke of an asteroid with a 1%–2% chance of a fatal collision occurring in 2032. While more recent measurements of Asteroid 2024 YR4 suggest the threat will not be realized this time, what about the next time?

😱 Earth's cosmic dance with danger! A recent asteroid posed a small collision risk—but what about the *next* one? ☄️ The threat is real… #AsteroidWatch

Is Venus hiding dangerous asteroids? Twenty years ago, the U.S. Congress instructed NASA to find 90% of near-Earth asteroids threatening Earth. They've made progress finding these asteroids that orbit the sun and come to within 1.3 astronomical units of Earth. However, they may have to expand their search since astronomers are now finding asteroids co-orbiting Venus that could pose a threat.

Hidden asteroid threats loom! ☄️ NASA’s 20-year search expands—now tracking Venus co-orbiters that could endanger Earth. Is our planet truly safe? #AsteroidWatch

Asteroid 2024 YR4: NASA Declares Earth Safe, Highlighting Planetary Defense NASA confirms Asteroid 2024 YR4 poses no Earth threat.

🌌 Navigating the cosmos reveals both wonders and threats. Recent findings confirm Asteroid 2024 YR4 poses no risk to Earth, thanks to advanced tracking technologies. Continued vigilance in planetary defense is key! 🌍✨ #AsteroidWatch #SpaceSafety

Earth Safe From 'City-Killer' Asteroid 2024 YR4 Asteroid 2024 YR4, once considered a significant impact risk, has been reassigned to Torino Scale Level Zero and therefore poses no hazard to Earth.

Earth Safe From 'City-Killer' Asteroid 2024 YR4 #Technology #Other #AsteroidWatch #SpaceNews #CosmicEvents

‘City Killer’ Asteroid Suddenly Declared Safe — What To Know Asteroid 2024 YR4's impact chance is now 0.002% and has been downgraded to Torino Scale Level 0, posing no threat to Earth, after recent observations.

Good news from @esa.int ! New observations have drastically shrunk the uncertainty window for asteroid 2024 YR4—its chance of striking Earth is now nearly zero. No existential threat here, just another day of precision science keeping our planet safe! 🌍 #AsteroidWatch

NASA changes odds of asteroid hitting Earth in 2032 yet again — but this time it's good news NASA increased the chances of asteroid 2024 YR4 hitting Earth to 1 in 32, or 3.1%, on Tuesday, but they're now back down to 1 in 67, or 1.5%.

Just had not one, but TWO asteroids swing by Earth:

• One waved from 1.37 million miles away.
• The other pulled a surprise dive over Siberia.

Somewhere, dinosaurs are side-eyeing us like, “You sure you’ve got this handled?”
