Dust ]]

• From January to December 2016, the researchers observed Tabby's Star in ultraviolet using Swift, and in infrared using the Spitzer Space Telescope.

• The smoking gun: Researchers found less dimming in the infrared light from the star than in its ultraviolet light. Any object larger than dust particles would dim all wavelengths of light equally when passing in front of Tabby's Star.
