Beta Pictoris System (NIRSpec IFU Image Annotated)

The newly discovered third planet orbiting Beta Pictoris, Beta Pictoris d, appears in reconstructed imagery from NASA’s James Webb Space Telescope’s NIRSpec (Near-Infrared Spectrograph). NIRSpec’s Integral Field Unit (IFU) was used to map chemical contents of the Beta Pictoris system. This allowed researchers to confirm the bright point of light, as seen in the image, was actually a planet by detecting its chemical composition.
Modeling suggests its orbit is comparable to the region occupied by Neptune in our own solar system.

Beta Pictoris System (NIRSpec IFU Image and Spectrum)
Researchers used the NIRSpec (Near-Infrared Spectrograph) Integral Field Unit on NASA’s James Webb Space Telescope to map chemical contents of the Beta Pictoris system. As a result, they discovered a third planet, Beta Pictoris d, orbiting the young star.
