Exoplanet VHS 1256 b (NIRSpec and MIRI emission spectrum)

A research team led by Brittany Miles of the University of Arizona used two instruments known as spectrographs aboard the James Webb Space Telescope, one on its Near Infrared Spectrograph (NIRSpec) and another on its Mid-Infrared Instrument (MIRI), to observe a vast section of near- to mid-infrared light emitted by the planet VHS 1256 b. They plotted the light on the spectrum, identifying signatures of silicate clouds, water, methane and carbon monoxide. They also found evidence of carbon dioxide.

[Image Description: Graphic titled “Exoplanet VHS 1256 b Emission Spectrum.” The label at top right reads NIRSpec and MIRI, IFU Medium-Resolution Spectroscopy. The spectrum is plotted on a graph with y- and x-axes. The graph shows jagged lines. There are labels for water, carbon monoxide, methane, and silicates.]
