Which type of light helps astronomers detect the hottest stars? Beyond violet lies ultraviolet (UV) light, whose energies are too high for human eyes to see. UV light traces the hot glow of stellar nurseries and is used to identify the hottest, most energetic stars.
What types of light do astronomers use to observe stars? Infrared light is given off by warm objects such things as protostars (stars about to be born), planets, moons, and brown dwarf objects.
