... It’s the size of the distances between the stars. And this cloud has stars forming in it. And in the upper right drawing — or picture; it’s actually a photograph — you see an arrow pointing at a couple of very bright stars that have just recently formed in this cloud. Now, here are a couple of color ...

Stars that appear brighter are on average closer to Earth. c. Large pulsating objects have longer periods tha ...

... The principal stars of Sagittarius form the famous “Teapot” asterism. The brightest part of the Milky Way seems to emerge from the Teapot's spout like a puff of steam. M22 The Great Sagittarius star cluster is a very large globular -- the best of the constellation's many globulars. At magnitude 5.1 ...

STELLAR CLASSIFICATIONS: TYPE “O” STARS
... Stellar objects with these classifications are not technically stars, but are still worth knowing. These are “sub-stellar” objects, commonly called red and brown dwarfs. What distinguishes these objects from real stars is that dwarfs do not undergo stellar fusion. Their cores never quite reach a hig ...

Continuous Spectrum—Kirchoff`s First Law

To understand this, we will consider the physics that goes on inside of stars. For the moment, we will just take it as a fact that we have determined observationally ...
