PPT-Life Cycle of a Star Nebula

Baby star Composed of gas and dust Protostar Center of nebula begins to shrink as it gets hotter Nuclear fusion begins Main Sequence Middle Age Star will spend most of its life in this stage. Hubble Telescope. Compiled by Chris Wolfram, RA University of Maryland-College Park. The Red Spider Nebula. . Huge waves are sculpted in this two-lobed nebula some 3000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometers high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image.. Life Cycle of A Star. Lesson Goals. 1. Define the terms: . Luminosity. , . Stellar Classification, Stellar Nebulae, .
