The fraction of galaxies described by this adjective in galaxy clusters increases alongside another variable in the Butcher-Oemler Effect. This adjective describes the star Sanduleak -69 202 in a 1987 Nature paper that described that star unusually being a progenitor for a supernova. (-5[1])This adjective names a “loop” that intermediate-mass stars may undergo when they begin burning helium. This adjective describes anomalously young stars in globular clusters like M53, which are called (*) “stragglers” (10[1])described by this adjective. Visible light is subtracted from light named for this adjective in a common index used on the x-axis of observational H-R diagrams. Along with white, this color describes the color of type-O stars (10[1])and the star Rigel, which all have low values for color index. Light’s wavelength [emphasize] decreases, and thus energy increases, in this color’s namesake “shift.” For 10 points, what color titles a Voyager 1 photo of Earth as a “pale dot?” ■END■
