The Lovely Sunset On Exoplanet HD 209458 b
Exo Sunset on Osiris Sunset on the extremely well-studied exoplanet HD 209458b, also known as Osiris, would look pretty much like this. The image was reconstructed from a transmission spectrum taken with the Hubble Space Telescope'a Space Telescope Imaging Spectrograph. Frédéric Pont We may never see the surface of a planet in another solar system, but that doesn't mean we can't imagine it with great accuracy. Equipped with careful observations, it's possible to visualize the sunset as it would look from a distant exoplanet. This is what it looks like. This image, created by exoplanet researcher Frédéric Pont, uses data from the transmission spectrum of exoplanet HD 209458 b, a.k.a. Osiris, one of the oldest known worlds in the exoplanet pantheon. It's a pretty big planet, about 70 percent the size of Jupiter, and it orbits very close to its sun-like star. As Osiris crosses in front of the face of...
