Located about 129 light years from Earth in the direction of the Pegasus constellation is the relatively young star system of HR 8799. Beginning in 2008, four orbiting exoplanets were discovered in this system which – alongside the exoplanet Formalhaut b – were the very first to be confirmed using the direct imaging technique. And […]

This really is a tremendous thing to be able to see exoplanets orbiting distant stars in other systems. Once upon a time, we would never have been able to do this sort of imaging where we can watch other planets orbiting another star--and now here we are! Like the writer of the article, I too would love to see a video of one of the gaseous planets around HR799 being ejected from the system. That would certainly be an entertaining event to see playing out in another solar system safely far away from our own. I feel that being able to image and research very young planetary systems would certainly give us deeper insights into the formation of solar systems like (or unlike) our own.
