Artist’s concept of the early stages of young star FU Orionis’ outburst. The star, a bright yellow sphere near the center, and its fluffy disk of gas and dust are slightly tilted, extending from the top left corner to the bottom right. The swirling disk is bright yellow close to the star and gradually transitions to dark orange moving toward the edges of the frame. The top left and right corners reveal a black, starless background.

Young star FU Orionis is pretty shocking! Astronomers used Hubble to observe the sizzling star in ultraviolet light. At 16,000 kelvins, nearly three times our sun’s surface temperature, its disk is nearly twice as hot as prior models have calculated: https://bit.ly/4fZwSU5
