An international team of astronomers has fixed a star in the work of devouring one of its planets. BD+48 740, a red giant they pragmatic using the 9.2-meter Hobby-Eberly Telescope at the McDonald Observatory in Texas, appears to have the gas of a scorched planet in its atmosphere. This is reliable with a rocky world, recently destroyed.
The great researchers who concentrate in stellar evolution have lengthy known that the inner planets are in danger. The trouble starts in the isolated future when the sun's core runs out of hydrogen fuel for nuclear fusion. To keep the fires flaming, the sun will begin to fuse hydrogen external the core, in a layer closer to the stellar surface. This will turn the sun into a red oversize, at least 200 times wider than it is today. Mercury, Venus, Earth and possibly even Mars might be engulfed.
The fate of Earth is not a confidence, however. Some researchers believe that Earth's orbit might spiral outward, keeping the planet at a safe space from the future inferno. This could happen if solar winds carry a path a major fraction of the sun's mass in the years most important up to the red giant phase. On the other hand, the sun might get bigger so fast that our planet has no chance to escape. Earth would get trapped in the sun's rapidly advancing atmosphere and spiral innermost to oblivion.
