00:00What if planets like Earth were born, thanks to alien visitors from deep space?
00:05Astronomers now believe interstellar objects like Comet 3i Atlas
00:08might be seeding the universe with planets.
00:11These aren't sci-fi aliens.
00:13They're real space wanderers, kicked out of other star systems
00:16and flung across the galaxy.
00:18A new theory suggests these rogue objects could get captured by young stars.
00:22Once inside, they act like planet starters
00:25providing the solid mass needed to grow new worlds.
00:28Normally, small rocks in space just bounce or shatter when they collide.
00:32But these interstellar seeds might help overcome that growth barrier.
00:36Millions of them could be trapped in a single protoplanetary disk,
00:40especially around massive stars.
00:42And that could explain why giant planets like Jupiter
00:45often form faster and around bigger stars.
00:48Comet 3i Atlas, spotted this summer, is only the third confirmed interstellar object
00:53to pass through our solar system.
00:55And its presence might prove that these cosmic hitchhikers are everywhere.
00:59So next time you gaze at the stars, remember,
01:02some of those planets may owe their existence to visitors from far beyond.
01:05And otherwise, we'll close you really want to see the stars,
01:08if you have new clothes in your supervisor and valuable data.
01:12Hello?
