How to Find 3 Different Kinds of Nebulae

The word nebula is Latin for "cloud." In astronomy, it describes an interstellar body of dusts and gases. Stars are born within nebulae. With advanced telescope technology, astronomers have been able to distinguish different types of nebulae. The Orion nebula is an emission nebula, the ring nebula is a planetary nebula, and the crab nebula is a diffuse nebula. These three are visible with a low-power telescope or the naked eye.

Instructions

  1. Ring Nebula

    • 1

      Locate Vega. It is the brightest star in the northern hemisphere in the summer sky.

    • 2

      Look down from Vega and trace out the diamond or parallelogram shape of the Lyra constellation.

    • 3

      Aim your telescope at the shortest side of the Lyra constellation. It's the side farthest from Vega.

    • 4

      Look in the middle of the line. You should see a distinct cloudy ring, the ring nebula.

    Orion Nebula

    • 5

      Locate the Orion constellation. It is most visible in January and February in the southern hemisphere.

    • 6

      Identify Orion's belt, which consists of three bright stars in a horizontal line at the center of the Orion constellation.

    • 7

      Move down from Orion's belt to locate Orion's sword, a line of vertical stars.

    • 8

      Point your telescope at the center of the sword. That is where the nebula is.

    Crab Nebula

    • 9

      Locate Betelgeuse and Almath on your star chart. Betelgeuse is a bright red star at the armpit of the Orion constellation. Almath is the second-brightest star in Taurus and represents its left horn.

    • 10

      Look for both stars in the night sky. Draw a line, mentally or with your finger, that connects them.

    • 11

      Focus your telescope on Betelgeuse. Move the telescope along the line toward Almath.

    • 12

      Look for the nebula in the telescope's lens. It is about two-thirds of the way to Almath, near the tip of Taurus's right horn. If you come to Almath, you have gone too far.
