NASA scientists have confirmed that a mysterious object shooting toward us through the solar system is an “interstellar object” — only the third of its kind ever seen. Experts have also given the cosmic interloper an official name, and revealed new information about its origins and trajectory.
News of the extrasolar entity, initially dubbed A11pl3Z, broke on Tuesday (July 1), when NASA and the International Astronomical Union (IAU) both listed it as a confirmed object. It was first discovered in data collected between June 25 and June 29 by the Asteroid Terrestrial-impact Last Alert System (ATLAS), which automatically scans the night sky using telescopes in Hawaii, Chile and South Africa. Multiple telescopes across the world have subsequently spotted the object in observation data that date back to June 14.
The object is traveling toward the sun extremely fast, at around 152,000 mph (245,000 km/h), and observations suggest that it is set on an extremely flat and straight trajectory, unlike anything else in the solar system. This led many experts to speculate that it originated from beyond the sun’s gravitational influence and has enough momentum to shoot straight through our cosmic neighborhood without slowing down.
