... This is a” thinking” question: Star A appears brighter than Star B, but Star A actually gives off less energy than Star B. The apparent magnitude and absolute magnitudes for Star A are m = 1 and M = -2, respectively. Use this information to answer the following two questions. 13) Which of the follow ...

Leo (The Lion) is our spring constellation that enters the beginning of the ‘Galaxy Constellations’ well into the summer months.

... • Perhaps the most famous is the “Crab Nebula” from a supernova in 1054 AD. It was so bright, Chinese, Japanese, and Arab astronomers saw it for months during the day, and could be seen for 2 years at night. • The remnant merges with other gas and forms new stars. • Supernovae occur 1 to 3 times per ...

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.
