00:00On July 1st, 2025, astronomers spotted a faint smudge on a one-way trip through our solar system.
00:09It was quickly designated 3-I Atlas, the third interstellar object ever found.
00:15This is a comet and a huge one, with a nucleus estimated to be up to 20 kilometers wide,
00:24potentially 10 times larger than our second visitor, 2-Iborosov.
00:30Unlike the bizarre, cigar-shaped Oumuamua, 3-I Atlas is a more familiar, fuzzy comet with a short tail.
00:38It's a pristine relic from another solar system.
00:41So how do you investigate a suspect moving at 150,000 miles per hour?
00:48We can't catch it, so it's a global race against time.
00:52The comet poses no threat, making its closest pass by the sun in late October 2025.
01:00Before being flung back into deep space.
01:04The proof of its alien origin is its hyperbolic trajectory.
01:08It's moving too fast for our sun to capture.
01:12Scientists are now using spectroscopy to read the chemical fingerprints in its gassy coma,
01:19analyzing material from another star system.
01:21So, what clues has it revealed?
01:25First, it's definitely a comet.
01:28Its fuzzy coma of gas and dust confirms it's an icy body,
01:33supporting the theory that most interstellar visitors are.
01:37Our last visitor, 2-Iborosov, was chemically similar to our own comets.
01:433-I Atlas provides a crucial second data point.
01:46Is its chemistry similar or totally different?
01:52The most exciting possibility is finding complex organic molecules,
01:57the building blocks of life.
01:59Discovering them would suggest the universe is filled with the necessary parts for life to begin.
02:06The verdict?
02:07This is an unprecedented moment.
02:10Solar systems aren't isolated islands.
02:12They're connected by messengers between the stars.
02:17Automated sky surveys made this discovery possible.
02:21But with the new Vera C. Rubin Observatory,
02:25scientists predict we'll find dozens, maybe hundreds more.
02:29We're about to study a true population of interstellar visitors.
02:34For now, 3-I Atlas is a time capsule from an unknown star,
02:39teaching us how to read the stories of the cosmos.
