The story of 'Oumuamua, the first visitor from another star system | Karen J. Meech 4.5
In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.

When aliens ride by our solar system in their UFO they tell their kids to lock the doors.

Kind of astronomy topic is what I love a lot, could TED invite more astronomers or researchers to talk about kind of issue like this?

It’s really interesting

If they are aliens

I just hope they're friendly refugees like district 9.

...and not evil New World Order aliens like XCOM 2

We should build a wall around our solar system. We can’t let illegal migrant asteroid get into our solar system. Let Mexico pay for it.

My dumb theory: it's an alien space ship that was in a vicious battle that disguised itself from its enemy and from us.
