Scroll through social media long enough and you will find it: "Something is coming in 2029." Short videos, viral posts and countdown clocks suggest an alien arrival. Let's separate what is known from what is internet folklore.
There is no single source, which is typical for viral legends. Several things have blended together:
As of today there is no verified evidence of extraterrestrial life visiting Earth, and nothing that points to an arrival in 2029. The US Department of Defense's All-domain Anomaly Resolution Office (AARO) has reviewed many reports and has stated that it found no verifiable evidence of extraterrestrial technology. Most sightings turn out to be balloons, drones, aircraft, satellites or sensor artifacts.
Astronomers also track the sky continuously. A large object approaching Earth would be detected months or years ahead, and that information would not be a secret.
That is a serious scientific question. Over 5,000 planets are confirmed outside our solar system, and some orbit in the habitable zone of their stars. Programs such as SETI listen for signals, and missions search for chemical signs of life. So far, none has produced a confirmed detection. The honest answer is: we do not know, and looking is worthwhile. But "possible somewhere in the universe" is very different from "arriving on a specific date."
An asteroid visit that is rare, real and verifiable, and a global chance for astronomers and the public to watch the sky together. That is exciting enough on its own. Follow our live countdown and we will keep this page updated with real news.
