No, the Milky Way galaxy was not formed from an expanding nebula. Instead, it formed through a process known as hierarchical clustering, where smaller clouds of gas and stars merged over billions of years to create larger structures. This process involved the gravitational attraction of matter in the early universe, leading to the formation of stars, star clusters, and eventually, galaxies. The nebular hypothesis primarily describes the formation of individual stars and planetary systems, not entire galaxies.
Yes, a spiral nebula is type of galaxy much like the Milky Way.
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.
No. Nebulae exist in almost every galaxy.
Yes, the Carina Nebula is located in the Milky Way Galaxy only 7,500 light years away from earth.
The Milky Way galaxy is vast, measuring about 100,000 light-years in diameter, while a typical nebula can range from a few light-years to several hundred light-years across. This means that the Milky Way is astronomically larger than individual nebulae, which are often regions of gas and dust where new stars are formed. For context, even the largest nebulae, like the Orion Nebula, are mere specks compared to the overall size of our galaxy.
The Pillars of Creation or the Eagle Nebula is only about 7,000 light years from us, so it is definitely in the Milky Way Galaxy.
Gravitational collapse of a protostellar nebula.
NO we live in eagle Nebula
M57, the "Ring Nebula", is in our own Milky Way galaxy, about 2300 light years away.
That's a planetary nebula within our Milky Way.
Yes, unless it's a galaxy or nebula outside of the Milky Way... all the singular stars you can see are within our galaxy.
Considering the size of the Milky Way Galaxy and the amount of "empty" space, the amount of space an emission nebula occupies is so small as to be infinitesimal and impossible to equate to a volume.
