Summary edit
| Description | This video shows four Jupiter-sized exoplanets orbiting billions of miles away from their star in the nearby HR 8799 system. The planetary system is oriented face-on toward Earth, giving astronomers a unique bird’s-eye view of the planets’ motion. The exoplanets are orbiting so far away from their star that they take anywhere from decades to centuries to complete an orbit. The video consists of seven images of the system taken over a seven-year period with the W.M. Keck Observatory on Mauna Kea, Hawaii. Keck’s coronagraph blocks out most of the starlight so that the much fainter and smaller exoplanets can be seen. |
