Longitude - Meridian Latitude - Parallels Units of Meridians and Parallels - Degrees 1 Degree of latitude - 112 km/70 miles 1 Degree - 60 minutes 1 Minute - 60 arc seconds Prime Meridian - Greenwich meridian Geostationary Satellites - Stationed at 0 degrees celestial latitude and each has a constant celestial longitude Parallax - The effect whereby the position or direction of an object appears to differ when viewed from different position

8. How is a nova different from a type Ia supernova? How does it differ from a type II supernova? - A nova is a smaller energy explosion on the surface of a white dwarf in a close binary system, where fresh material from a donor star is deposited on the surface of the white dwarf until it ignites. A type Ia supernova has a similar configuration, but in this case, the material deposited on the surface of the white dwarf is sufficient to push the white dwarf past the Chandresekhar limit....

To get started, click on the blue Cepheids link on the main screen of the Interactive Figure. The Interactive Figure (in red) shows a graph of the Cepheid period-luminosity relation. This graph indicates that __________. - Cepheids with longer periods have higher luminosities A Cepheid with a period of 30 days has an average luminosity that is about __________ times the luminosity of the Sun. - 10,000 Click on the blue "Cepheid" label, then click the label on the bottom of the Intera...

Astronomy - Final Exam With Complete Solutions 100% Solved How are galaxies created? ️️One says that galaxies were born when vast clouds of gas and dust collapsed under their own gravitational pull, allowing stars to form. ... The other, which has gained strength in recent years, says the young universe contained many small "lumps" of matter, which clumped together to form galaxies. How was Hubble important to our understanding of galaxies? ️️he discovered the existence of ...
