Dimming of FU Orionis (Fainter Phase Artist's Concept)

This artist's concept illustrates how the brightness of outbursting star FU Orionis has been slowly fading since its initial flare-up in 1936. The star is pictured with the disk of material that surrounds it. Researchers found that it has dimmed by about 13 percent at short infrared wavelengths from 2004 (left) to 2016 (right).

This illustration represents the fainter disk inferred from 2016 data was collected with the Stratospheric Observatory for Infrared Astronomy (SOFIA).

FU Orionis is a few hundred thousand years old. It is possible that when our sun was younger, it also went through a period of intense brightening followed by dimming.
