The constellation Orion contains at least 4 galaxies.
and many other open clusters.
Note: These galaxies lie far, far beyond the group of stars delineating the perimeter of the Orion Constellation. By "contain" we just mean we can see these galaxies out the Orion window.
There is no galaxy specifically known as "Orion Galaxy". Of course, there are millions of galaxies in the Orion constellation, just as there are millions of galaxies in any other direction.
No, Orion is not an elliptical galaxy. Orion is actually a constellation in the night sky, known for its prominent stars like Betelgeuse and Rigel. Elliptical galaxies are large, rounded, and featureless galaxies that are different from individual stars or constellations.
Sorry - that's so tangled it's hard to establishthe question's meaning. There is a nebula, or star cluster, within (i.e. framed by) Orion; and Orion is part of our own galaxy. I don't know if the nebula is in our galaxy or not. Galaxies are thought now to have huge black holes in their centres, holding the structure together by their gravitational attraction.
The Orion galaxy is not getting wider. Galaxies are huge collections of stars, gas, and dust held together by gravity and don't expand in the same way the universe does. The distance between galaxies is increasing due to the expansion of the universe, but individual galaxies like Orion remain the same size.
All galaxies contain hot blue stars...
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
None. Galaxies on the other hand do contain planets
Galaxies can be classified into three main sizes: dwarf galaxies, which are small and contain less than a few billion stars; Milky Way-sized galaxies, which are intermediate in size and contain a few hundred billion stars; and giant galaxies, which are massive and can contain trillions of stars.
Spiral and irregular galaxies.
yes
Yes. Some spiral galaxies do contain at least 1 trillion stars.
