00:00A mysterious visitor from deep space just did the unthinkable.
00:03It appeared to reverse thrust, before vanishing behind the Sun.
00:07Meet Three-Eye Atlas, an interstellar comet that has astronomers scratching their heads.
00:12Back in July, Hubble spotted something bizarre,
00:15a jet of dust shooting toward the Sun.
00:18Not away from it like comets usually do.
00:20This strange feature, called an anti-tail, looked like the comet was defying physics.
00:25But new images from the Nordic Optical Telescope reveal the twist,
00:29that anti-tail? It's now gone.
00:32Replaced by a normal tail, pointing away from the Sun.
00:35Here's the wild part.
00:37This reversal wasn't alien tech or a mistake.
00:40It was sunlight.
00:41Big, slow dust grains first created the backward-pointing glow.
00:45But as the comet got closer to the Sun, heat kicked in.
00:48It started ejecting gas and lighter dust, forming a tail that now streams outward.
00:53Right now, Three-Eye Atlas is hidden behind the Sun, impossible to track.
00:58But before it vanished, NASA confirmed it was losing 330 pounds of material every second,
01:04mostly carbon dioxide.
01:06This interstellar traveler just gave us a cosmic magic trick,
01:09and scientists are watching closely for its next move.
