Scientists say 3I/Atlas came closest to Mars in October. Its path this month put it in the path of the warm rays of our sun, where a tail became more visible. The 3.5-mile solar object is traveling at 137,000 miles per hour, NASA said.

In fact, quite the opposite is true: Every piece of evidence collected about 3I/ATLAS to date is consistent with a natural, cometary origin – a highly weird comet, to be sure, but a comet nevertheless. And, actually, that's really interesting and cool, without needing the assistance of imaginary aliens to make it so.

A mysterious visitor from beyond our solar system is making a rare appearance: Comet 3i/ATLAS is an interstellar comet, traveling at breakneck speed and carrying clues from a distant star system billions of years old.

Blue Origin's New Glenn rocket was scheduled for launch on Sunday (Nov. 9) but it has been delayed until Wednesday (Nov. 12) due to poor weather conditions. The launch will be the first big test for the rocket’s first NASA mission, and a statement of intent for the company’s founder Jeff Bezos against competitor SpaceX.
