The HR 8799 system harbors four super-Jupiters orbiting with periods that range from decades to centuries. We're currently monitoring this system to understand if and how this system is dynamically stable. This footage consists of 7 images of HR 8799 taken with the Keck Telescope over 7 years. Video made by Jason Wang, data reduced by Christian Marois, and orbits were fit by Quinn Konopacky. Bruce Macintosh, Travis Barman, and Ben Zuckerman assisted in the observations.

A Crescent Earth At Midnight - October 6th, 1996.
"The Earth's northern hemisphere appears outlined as a sunlit crescent in this dramatic view from the GOES 8 satellite. The image was made near midnight for the Geostationary Operational Environmental Satellite on June 22nd, 1996, two days after the summer solstice. The summer solstice is the time of year when the Sun reaches its greatest northern declination and the arctic regions near the top of the picture experience 24 hours of daylight. Looking south along the Earth's limb, atmospheric scattering of sunlight causes the bright crescent to be visible beyond areas directly illuminated by the Sun."
