NASA Massive comet zooming through solar system could be alien technology, Harvard astrophysicist says

A comet traveling outside the solar system and heading toward the Earth is much larger than scientists first believed, a scientist has detailed in a new report.

Avi Loeb claims the comet could even be an artifact of alien technology rather than a natural body because it weighs more than 33 billion tons and spans at least 3.1 miles across.

The object, named 3I/ATLAS, is only the third interstellar visitor ever detected, after Oumuamua in 2017 and 2I/Borisov in 2019.

The astrophysicist also revealed in a Medium blog post that new data and measurements indicate the comet’s nucleus is more massive than first estimated.

3I/ATLAS was spotted in July with observations showing the comet is shedding huge amounts of carbon dioxide and dust as it races toward the Sun.
