NASA's bizarre discovery on an object from another star system #space #astronomy

[00:00:02]Far beyond the orbit of Neptune, beyond the frozen edge of the solar system, beyond the reach of the sun's warmth, something was moving through the darkness. [music] It was not born here. It did not form beside Earth, Mars, Jupiter, or Saturn.

[00:00:17]It came from somewhere else. Another star system, another planetary neighborhood, another chapter of the galaxy. For millions, maybe billions [music] of years, it drifted through interstellar space, silent, frozen, untouched. Then one day, it entered our solar system. Astronomers gave it a name, 3I/Atlas.

[00:00:40]Only the third confirmed interstellar object ever detected passing through our cosmic neighborhood. And now, NASA's James Webb Space Telescope has looked at it more closely than ever before. What Webb found was not a signal from aliens.

[00:00:54]It was not a spaceship. It was something more subtle, and in some ways more powerful. A chemical clue, a frozen memory from another solar system, methane. [music] For the first time, Webb directly detected methane gas on an interstellar visitor.

[00:01:10]>> [music] >> And that discovery raises a haunting question. What secrets are hidden inside objects that come from beyond our sun?

[00:01:18]Because 3I/Atlas is not just a comet, it is a messenger, [music] a piece of another star system passing through ours one [music] time only. And once it leaves, it may never return.

[00:01:32]This is infinite [music] science, and tonight, we are following a visitor from another star. Most comets in our solar system are ancient leftovers. [music] They are frozen fragments from the time the planets were forming. They carry [music] ice, dust, carbon compounds, and gases locked away for billions of years.

[00:01:50]>> [music] >> When a comet comes close to the sun, heat begins to wake it up. Ice turns directly into gas. Dust erupts from the surface. A glowing coma forms around [music] it. A tail stretches into space.

[00:02:04]And suddenly, this dark frozen object becomes visible. But 3I/Atlas is different. This comet did not come from the outer edge of our solar system.

[00:02:14]It came from interstellar space. That means it was likely formed around another star.

[00:02:20]Somewhere in the Milky Way, in a distant planetary system we may never see clearly, >> [music] >> 3I/Atlas was created out of ice, dust, and ancient chemistry. [music] Then, at some point, it was thrown out. Maybe by a giant planet. Maybe by a gravitational collision. Maybe by the chaos of a young solar system still under construction.

[00:02:42]And once it was ejected, it became a cosmic wanderer. No home. No orbit around a star. Just a frozen body traveling through the galaxy >> [music] >> until it crossed paths with us. Imagine the scale of that journey. [music] The Milky Way is enormous. Stars are separated
