What are the two important discoveries Hubble made that proved other galaxies exist outside our own?
Hubble discovered that the nebulas were galaxies based on the powerful telescope at Mt Wilson. The second discoveries was the red shift relationship v=HD shows that the galaxies were outside our own galaxies definitely and quantitatively, using light sources in galaxies that were standard sources that could calibrate the distance.
What are the other stars if seven or eight of them are other planets?
They are either other solar systems, nebulas (Dead solar systems) Blackholes, other galaxies or stars that have no orbits
Are nebulas in elliptical galaxies?
Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.
HOW Are supernovae and nebula's similar?
Supernovae and nebulas are similar in that they are both astronomical phenomena related to the lifecycle of stars. Nebulas are vast clouds of gas and dust where stars are born, while supernovae are the explosive deaths of massive stars that release heavy elements into space, enriching the surrounding nebula. Both play critical roles in the formation and evolution of galaxies.
Where is the stellar nebula found in the lifecycle of stars?
stellar nebulas are the birthplace of stars. 1st of the sequence in the lifecycle of stars.
Who proved that there are galaxies besides the milky way?
Hubble, in his studies of Nebulas which turned out to be galaxies.
What are two most common elements in nebulas?
The two most common elements found in nebulas are hydrogen and helium. These elements are the building blocks of stars and galaxies, and are formed during the process of stellar nucleosynthesis.
What type of galaxys are nebulas often found in?
There are many types of nebula and they can form within any galaxy. Generally, the normal types of nebula - planetary and supernova remnants will occur in the younger galaxies, so at a push spiral galaxies.
What objects can be seen from earth because they produce their own light?
Cities can be seen from space.
How do you find galaxies?
Look up in the sky with a good telescope, and find things that are too fuzzy-looking to be stars. Some of them are nebulas, and a few may be comets - but a lot of them are other galaxies.
What can be seen from Earth?
All sorts of things. The Sun, the Moon, planets, asteroids, meteors, galaxies, nebulas, satellites and other things.
Who found the galaxies?
who discovered the galaxies who discovered the galaxies

How many types of nebulas are there that are known?
There are primarily five types of nebulas: planetary nebulas, reflection nebulas, emission nebulas, dark nebulas, and supernova remnants. Each type of nebula has distinct characteristics and origins.
What are the other stars if seven or eight of them are other planets?
They are either other solar systems, nebulas (Dead solar systems) Blackholes, other galaxies or stars that have no orbits
Why are the stars found in galaxies?
Because that is what galaxies are "made" up of.
