A Four Planet System, Directly Imaged and Remarkable

This is truly remarkable! A four planet system, directly imaged with the Keck observatory in Hawaii.

Link to video of a Four Planet System:

"This evocative movie of four planets more massive than Jupiter orbiting the young star HR 8799 is a composite of sorts, including images taken over seven years at the W.M. Keck observatory in Hawaii."

"The movie clearly doesn’t show full orbits, which will take many more years to collect. The closest-in planet circles the star in around 40 years; the furthest takes more than 400 years."
