The Cаse оf the Mystery Nebulа Scenаriо: An astrоnomer discovers a new nebula (Cloud X) and wants to determine its future. Observation 1: Spectroscope data shows that the light from the nebula is Blue Shifted. Observation 2: The nebula contains a star that is extremely bright (luminous) but has a low surface temperature (appears red). Question: Based on these observations, predict the movement of this nebula relative to Earth and identify the current life-cycle stage of the star within it. Explain how it is possible for a "cool" star to be so bright. (4 Marks)
