Many young stars are still embedded in the clouds of gas and dust from which they, and any associated planets, were formed. For example, from the Northern hemisphere, the famous Orion Nebula (Figure 3-29) is visible in the winter evening sky, while the Lagoon, Omega, and Trifid nebulae are visible in the summer night sky. Examine some of these nebulae with a telescope. Describe their appearances. Looking at each nebula, try to determine which stars in your telescope's field of view are actually associated with the nebulosity. Use the Find pane in Starry Night Enthusiast™ to help you to find these nebulae. The table below gives their coordinates (right ascension and declination; see Section 1-3).
