For years, astronomers have wondered whether stars similar to the Sun go through periodic cycles of enhanced X-ray activity, like those often causing troubles to telephone and power lines here on Earth. ESA's X-ray observatory XMM-Newton has now revealed for the first time a cyclic behaviour in the X-ray radiation emitted by a star similar to the Sun. This discovery may help scientists to understand how stars affect the development of life on their planets. You can read the full story here. Greetings from Belgium. |
