A Four Planet System, Directly Imaged and Remarkable

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

“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.”
