Topic: Comet Whacked Neptune 200 Years Ago

[sam]

Researchers studying Neptune's atmosphere found evidence that a comet may have hit the planet about two centuries ago. Was this a "cold-case" file re-opened, or did they discover a way to travel back in time to witness a long-ago event? To make the discovery, a team from the Max Planck Institute for Solar System Research actually used the Herschel Space Telescope's PACS (Photodetector Array Camera and Spectrometer) instrument, along with what was learned from observations from when the Shoemaker-Levy 9 hit Jupiter sixteen years ago.
