The sky over New Zealand lit up with a brilliant green flash on January 30, 2026, leaving many wondering about its origin. Was it a regular meteor or something more extraordinary? The answer might surprise you.
A meteor traveling at an astonishing 71 kilometers per second relative to Earth zipped past our planet, and at first glance, it seemed like a typical solar system visitor. However, a closer look reveals a fascinating story. But here's where it gets controversial...
The upper limit for the impact speed of solar system meteors is determined by the Earth's orbital speed and the Sun's gravitational pull. This speed, around 71.9 kilometers per second, is incredibly close to the speed of the 2026 meteor. And this is the part most people miss...
This proximity in speed suggests that the meteor could have originated from within our solar system, possibly from the outer regions. However, the key question remains: Is it interstellar in origin?
Let's delve into the intriguing world of interstellar meteors. In June 2023, an expedition led by the author, Avi Loeb, sought to retrieve materials from the first-ever recognized interstellar meteor, IM1. This meteor, detected in 2014, had a velocity of 45 kilometers per second relative to Earth, but it arrived from behind our planet's motion around the Sun. And this is where things get even more interesting...
Correcting for Earth's motion revealed a speed of 60 kilometers per second relative to the Sun, surpassing the escape threshold for solar system objects. The U.S. Space Command confirmed IM1's interstellar origin with 99.999% confidence. The expedition uncovered unique submillimeter-scale spherules with a chemical composition unlike anything found in our solar system.
Now, back to the 2026 meteor. By analyzing its velocity components and correcting for Earth's motion, the author and his postdoc, Richard Cloete, discovered that the meteor's speed relative to the Sun was a mere 42.4 kilometers per second, very close to the solar system's escape threshold. This is where the controversy arises...
Given the abundance of solar system objects, it's highly likely that the 2026 meteor also originated within our solar system. It collided with Earth nearly head-on, suggesting an origin in the outer solar system. Interestingly, this meteor exploded at a much higher altitude than IM1, implying lower material strength due to the Earth's atmosphere at that height.
The search for interstellar meteors continues, and the author expresses hope for future discoveries, including the crash of an interstellar object with Voyager-like characteristics from an extraterrestrial civilization. So, what do you think? Do you agree or disagree with the author's findings? Share your thoughts in the comments!
