Astronomers discovered a giant planet that survived the brutal death of its star

Our sun has a time limit. It will reach the end of its life in about 5 billion years from now. What will our solar system look like after the sun dies? Astronomers have discovered a distant solar system It implies the fate of our planet. Earth will probably be struck, but Jupiter may survive.

NS A study published Wednesday in Nature Details of a Jupiter-like planet in a Jupiter-like orbit around a dead white dwarf. This system is near the center of the River of Heaven, and discoveries made through the WM Keck Observatory in Hawaii are the number of planets in our own system, even after our stars have passed the tantrum at the end of their inevitable lifespan. Shows that it may continue to exist in the distant future.

“This evidence confirms that planets orbiting long enough can continue to exist after their death.” Leading author Joshua Blackman said, Postdoctoral fellow at the University of Tasmania, Australia. “Given that this system resembles our own solar system, it suggests that Jupiter and Saturn may survive the Sun’s red giant phase when they run out of nuclear fuel and self-destruct.”

Our sun is expected to go through several stages when it dies. It expands to a red giant, Phases described by NASA “Usually the most violent time in a star’s life.” This is the time when the Earth is likely to be beaten, uninhabitable and destroyed.

Next, the sun will settle in the shape of a white dwarf, becoming a dead star that cools and disappears. It’s the kind of star that astronomers have found orbiting planets like Jupiter.

Co-authored with David Bennett of the University of Maryland NASA The Goddard Space Flight Center has suggested that it may be worth considering the movement of Jupiter and Saturn to the Moon. It assumes that humanity is still around. That means that our long-term ambitions for interplanetary life should include seeing some of Jupiter’s fascinating moons. Europe, the target of future NASA missions..

Moving to Jupiter’s neighborhood does not solve all of our problems. As Bennett pointed out, “… we will not be able to rely on the heat of the Sun as a white dwarf for a very long time.”

Some previous studies, including A 2020 treatise depicting a giant planet that fought off destruction Show that your own stars have the potential to survive, even though these stars tend to go out in the flames of glory. Scientists are still figuring out how common or rare this is.

The end of our sun is not an urgent issue for humankind, but thinking ahead is not a bad idea. A highly optimistic, sci-fi-inspired vision that extends beyond Earth, Mars, and even Jupiter to reach out to human civilizations in the distant future that extend to other solar systems long before the Earth toasts. You may see.
