John Hefele Nov 23 2014 Heart Nebula Basic Information Other Names IC 1805 Sh2190 Object Classification Emission Nebula Distance 7500 Light Years Size 180 Light Years 20 Arc Minutes across. Building Part 1. Solar Nebula’s Chemical Composition. Chemical Composition. Everything astronomers know about the solar system indicates that it . began as an interstellar gas cloud. .. Cloud would have been mostly hydrogen with some helium – small amounts of the heavier elements.. 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.. S. econd . P. eriod. Bob Jones, CERN. First Helix Nebula Review. 03 July 2013. This document produced by .
