It turns out that even after studying our solar system in depth and discovering more than 6,100 exoplanets across more than 4,500 exoplanetary systems, not all solar systems are created equal. The longstanding notion is that planets orbit almost entirely in the same orbital path, also called an orbital plane. But what if an exoplanetary system was found to have exoplanets that not only orbit in different planes, but also exhibits changing behavior regarding when they pass in front of their star? from Universe Today https://ift.tt/FjbdXk3 via IFTTT
The Moon has played a huge role in the development of Earth. It stabilizes the planet, tempered dramatic climate swings, and possibly even provided the tidal heating that might have led to the first life forms. So it’s natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers have been searching for one for years at this point to no avail. And a new paper from Emily Pass and her colleagues at MIT, Harvard, and the University of Chicago describes using the James Webb Space Telescope to track some of the most promising exomoon candidates - only to be foiled by the star they were orbiting. from Universe Today https://ift.tt/QrEFtHe via IFTTT
