This image is a composite of many separate exposures made by the STIS instrument on the Hubble Space Telescope. This image was originally black and white and recorded only overall brightness. These brightness values were translated into a range of reddish hues. Such color "maps" can be useful in helping to distinguish subtly varying brightness in an image. Red: STIS/CCD

Rogue Planetary Orbit for Fomalhaut b
This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The planet will appear to cross a...

Schematic of Fomalhaut System
This diagram shows the orbit of the exoplanet Fomalhaut b as calculated from recent Hubble Space Telescope observations. The planet follows a highly elliptical orbit that carries it across a wide belt of debris encircling the bright star Fomalhaut. The planet swings as close to...
