Beta Pictoris spectra

Beta Pictoris spectra
Beta Pictoris spectra This comparison of spectra from the Spitzer Space Telescope (2004-2005) and the James Webb Space Telescope (2023) shows a dramatic change in the dust surrounding the star Beta Pictoris. Scientists believe that a massive asteroid collision, evident in the Spitzer image, has largely cleared up by the time of the JWST observations.
