The Pristine Visitor From Another Star

The video discusses the discovery and study of interstellar objects Oumuamua and Borosov, highlighting Borosov's unique characteristics and formation. It also explores the pristine nature of Borosov through polarization studies. Additionally, the video covers new research on Saturn's moon Enceladus, suggesting a global ocean current beneath its icy surface.

What makes comet Borosov different from typical comets in our solar system?

• It has a fluffy dust composition.

• It contains more carbon monoxide.

• It lacks a characteristic tail.

• It is smaller in size.

What did the Nature Communications paper reveal about Borosov's dust?

• It is identical to Earth's dust.

• It is composed mainly of ice.
