Why do astronomers locate black holes?

Astronomers are constantly investigating and collecting information on any objects in space that have not yet been cataloged. In the course of doing this, they find and identify galaxies, nebulae, novas and, of course, black holes. They just "turn up" frequently as part of the never-ending search of the universe and the objects in it.


How can astronomers tell how much objects in space weigh?

Weight is due to gravitational forces between two objects. A single object inspace without another one reasonably nearby, or even in gravitational free-falltoward another object, is weightless. So you can not weigh an object in space.Determining the mass of objects in space is another matter.


What are differences in colors of moving objects in space that are approaching and moving objects that are moving away?

Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
