The interstellar comet 3I/ATLAS has a thick irradiated crust that no longer resembles its home star system, simulations and James Webb Space Telescope observations have found.

"The implication of alien technology would be huge and therefore we must take it seriously,” Harvard's Avi Loeb told Newsweek.

The comet is on what’s known as a hyperbolic trajectory, which means that it doesn’t follow an orbital path around the sun. It’s also traveling at about 137,000 miles per hour, which is too fast for the comet to be slowed down by the sun’s gravity.

Astronomers are hustling to use interplanetary spacecraft to study the interstellar comet dubbed 3I/ATLAS while the sun is hiding it from Earth

The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas surrounding it.

Astronomers have identified Comet 3I/ATLAS as an interstellar object, making it only the third confirmed visitor from outside our solar system, according to NASA.<br /><br />The comet is travelling on a hyperbolic trajectory,

Interstellar comet 3I/ATLAS baffles scientists, brightening 7x faster and turning blue. A Harvard expert suggests its strange path is a 'possible hint of design'.

Physicist Michio Kaku is warning about the AI-generated deepfakes, which exploit his image to push the idea the comet '3I/ATLAS' is an alien spacecraft that poses a potential threat.
