AST 1004 Part 15 Star Temperature Discussion , Part 2
Now Lets Continue with the discussion with discussing how telescope filters are used:
Here we go:
For example, an B filter ( which is blue filter , does not accept and therefore rejects all radition
AST 1004 Part 14 Star Temperature Measurement, Part 1
The next topic of discussion is Stellar Temperatures.
Stellar Temperature is ( stars temperatures.)
Well, How do we define the stars temperatures?
Well, when an person looks at the night sky, that indi

Lets continue: How is the stars apparent magnitude measured ?
Answer: The stars apparent magnitude is measured when an star is seen at its actual distance
from the Sun.
However, to compare the intrinisic, or absolute ,properties of the st
AST 1004 Part 12
Now , Lets continue by giving some examples on how the star magnitude scale is used.
To follow is an table of various astronomical objects apparent magnitudes.
Here we go: The 1st object in the table that is the most brightest object in t

Magnitude scale history, Part 2
When the astronomers began using sophisticated and unique telescopes with detectors, that
measure the amount of light that is measured from each and every star, They quickly discovered
2 important and vital

The next topic of discussion is the Magnitude Scale.
The stars magnitude is used for measuring the stars, However, it is not measured in regular SI
Regular SI Units include watts per square meter.
Instead of SI units, the astronome

Now Lets Move on to the Next topic of Discussion : The Inverse Square Law .
The Inverse Square Law states the following: As light moves away from an source ( for
example, such as a star, it( the object steadily dilutes while spreading over
AST 1004 Part 4- The Next topic of discussion is Our Nearest Neighbors, ( or in this case, the
stars that are close to the Human home planet, which is obviously Earth.
First of all, the closest star to the humans home planet, is indeed the Sun for sure.
AST 1004 Part 3
However, there are some occasions/ cases/ times when astronomers/exploration leaders can
extend the baseline to the diameter of Earths orbit around the Sun, about 2 Astronomical Units ,
It is only then, that that some of the parallax

Now, Lets continue our discussion with another topic:
Stellar Motion- Stars have an apparent motion/movement caused by the process of parallax.
In addition, stars have a real spatial movement throughout the galaxy as the stars move around,
AST 1004 Part 5
Even though it is the true that the previously mentioned area ( where we left off with talking
about in the previous section has nearly/close to an number of a million stars , the vast
majority(most of the stars in our (Earths Galaxy meani
AST 1004 Part 1- Astronomy of the Stars and Galaxies
The Galaxy in which we, humans live near is called the Milky Way.
It is an enormous collection of stars and interstellar matter held together by gravity.
The Milky way contains more than 100 billion sta
