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.

Bubble Nebula

The Bubble Nebula, also known as NGC 7635, is an emission nebula located in the constellation Cassiopeia.

It is approximately 7,100 light-years away from Earth. The nebula gets its name from its distinctive bubble-like shape, which is created by the stellar winds from a massive central star,

The Bubble Nebula is notable for its intricate structure, which includes a shell of ionized gas and a central cavity. The nebula is also a site of ongoing star formation, with new stars being born from the surrounding material.
