RCW103: The star and the mysterious friend?

When a star is 8 times more massive than the sun, it will end its life with a spectacular explosion known as a meteor.

The great tremors of this explosion will impact stars thousands of miles away within an hour, leaving countless gases and dust. Is that the cause of this mystery?

The latest images taken with X-rays of RCW103 - the 2000-year-old remnant of an explosion, 1000 light-years away from Earth - gave us a surprise about this star. It consists of 3 colors of red, green and blue arranged in 3 levels from low to high of X-rays.

At the center, a bright blue dot like a smaller star - which scientists believe is born of an explosion. Strangely, this small star has emitted X-rays for several years and it turns more slowly than stars of the same age (6.7 hours / time).

To explain the mystery of this star, the scientists thought: it was not born from the explosion, or rather it was too small and fuzzy to observe. The gas left from the explosion of the surrounding planets may be a source of X-rays for this star; force from interaction between RCW103 and it may be the cause of slow rotation. But it's all a hypothesis .
