- 1 A Galaxy Revealed Among the great astronomical mysteries x the 1800s were the spiral nebulac, which appeared in telescopes as swirling cloadlike forms, bu whose nature was unknown Four different renderings of one such spiral nebula, designated M5!are shown in Figure 15-5 Figure 15-5A is a drawing from 1845 by William Pursons, the Earl of Rosse, who viewed MSI through what was then the world's larges telescope and sketched what he saw Figure 15-5B is a picture from 1889 by English amaceur astronomer Isaac Roberts, and is perhaps the first-ever photograph of MS1. Figure 13.5C is a 1950 photograph that was taken through the largest -in-the-world telescope of that era, the 200 -inch Hale reflector on Mr. Palomar in Califomia Figure 15-5D was obtained with the Hubble Space Telescope in 2005. Today we know that spiral nebaline like MSI are actually spiral galaxies, vast star systems like our own Milky Way galaxy. 11. Compare the four pictures of MSI. Describe similarities and differences 14. What factors might have led to the paticeable improvements in these images over time?
