... A blue giant is very bright. Like a light house, they shine across a great distance. Even though blue giant stars are rare, they make up many of the stars we see at night. Blue giant stars die in a spectacular way. They grow larger just like the Sun sized stars, but then instead of shrinking and for ...

E3 – Stellar distances
... • When we observe another galaxy, all of the stars in that galaxy are approximately the same distance away from the earth. What we really need is a light source of known luminosity in the galaxy. If we had this then we could make comparisons with the other stars and judge their luminosities. In othe ...

... Messier 37 is our third open cluster, and this is my personal favorite. To find it, jump across that imaginary line between Beta and Theta Aurigae to a spot about midway along the line but just outside the pentagon. There you will encounter a much more compressed cluster about 4400 light years away. ...

The giant star runs out of fuel and collapses in on itself, and ultimately the explosion leads to its death. Our Sun is not massive enough to blow itself into pi ...
