Locating things in the Sky
... We use a system called Right Ascention (RA) and Declination (dec). RA is like longitute and describes how far round an object is, and declination is like latitude and describes how far up or down an object is. We can use these measurements to determine the location of all things in the sky. Example: ...

Patronage in astronomy
Patronage in astronomy is an approach which one can use to examine the history of astronomy from a cultural standpoint. Rather than simply focusing on the findings and discoveries of individual astronomers, this approach emphasizes the importance of patronage in shaping the field of astronomy.
