Artist's View of a Sunset over KELT-9b (IMAGE) Université de Genève Caption Artist's view of a sunset over KELT-9b. The nearby warm blue star covers 35° in the planet's sky, about 70 times the apparent size of the sun in the Earth's sky. Under this scorching sun, the planet's atmosphere is warm enough to shine in reddish-orange tones and vaporize heavy metals such as iron and titanium.
