jerome drevon, thank you very much. let's move on.y, has six planets about the same size, which have barely changed since their formation of the 12 billion years ago. these undisturbed conditions make it ideal for learning these undisturbed conditions make it idealfor learning how these undisturbed conditions make it ideal for learning how the worlds were formed and whether they host life let's now speak to our science correspondent. hello, pallab. oh, we will see a report. our solar system had a violent beginning. worlds crashed into each other as they formed, disturbing their orbits. eventually, it led to planets are vastly different sizes that we know today. but if we travel through space 100 light—years, we find another solar system, but one that was created in much calmer conditions without so many violent collisions. the system has six planets, or of a similar size. their orbits haven't been disturbed, and so are in perfect harmony. it also has a bright star that makes it easier to study the atmospheres for signs of life. easier
