... What are three properties that distinguish elliptical galaxies from spiral galaxies? Spiral galaxies have spiral arms, gas, and young stars. Elliptical galaxies do not have arms, or a disk like structure, are mostly older stars, and contain very little gas. How do spiral galaxies form? A protogalact ...

Lab 8: Stellar Classification and the H
... As early as the beginning of the 19th century, scientists have studied absorption spectra in an effort to classify stars. At first, spectra were divided into groups by general appearance; however, in the 1930’s and 1940’s, astronomers realized that spectral type was mainly determined by temperature ...

Cassiopeia (constellation)
Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in Greek mythology, who boasted about her unrivalled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today. It is easily recognizable due to its distinctive 'M' shape when in upper culmination but in higher northern locations when near lower culminations in spring and summer it has a 'W' shape, formed by five bright stars. It is bordered by Andromeda to the south, Perseus to the southeast, and Cepheus to the north. It is opposite the Big Dipper.In northern locations above 34ºN latitude it is visible year-round and in the (sub)tropics it can be seen at its clearest from September to early November in its characteristic 'M' shape. Even in low southern latitudes below 25ºS is can be seen low in the North.
