Mainly in that gravity is involved in both cases.
A Starburst Galaxy is a galaxy with an exceptionally high rate of star formation, compared to other galaxies.Galaxies usually have a burst of star formation after a collision or close encounter between two galaxies.Because of the rate of star formation and the amount of available hydrogen, starburst galaxies are presumed to be temporary.M82 (Cigar Galaxy) is a well known starburst galaxy [See related link]
I said WHERE?!
the ellipitical galaxy is the hottiest galaxy
For sure. The current rate of star formation is about one a year.
In molecular clouds, such as the Orion Nebula.
The "real" answer is a protogalaxy or primeaval galaxy as these are the first stages in the formation of a galaxy.However, it's more than likely, the question has to do with new star formation, in which case, it will be a spiral galaxy (but the galaxy is not young) Our galaxy - the Milky Way - is about 13.2 billion years old - almost as old as the Universe itself.
Well, if you look at it from space, like from telescopes you can notice the form of the milkyway is a spril looking, star formation.
Most of the times, the brightest part of the galaxy is at the ceentre due the higher density of stars .Also if the galaxy is a spiral then the brightest part of the galaxy are the spiral arms because they are the star formation areas in the galaxy
quasar
Like all stars you can see at night, Betelgeuse is in our galaxy, the Milky Way.
sun is the brightest star in the galaxy
Vega is one star, not a group of stars. Vega, like any other star that can be seen with the naked eye, is in our own galaxy, i.e., in the Milky Way.
