The Milky Way appears to have a huge (even for a black hole) gravitational object at the center of it, and this is supposed by a lot of scientists to be a black hole. The arms of our galaxy sweep around the center.

The Milky Way.
Such a galaxy is called a spiral galaxy.
Yes. All galaxy objects revolve around the centre of mass, which we believe is a massive black hole.
Our galaxy, the Milky Way, is a spiral galaxy (actually a bared spiral) and new stars are being born in the spiral arms.
They are objects that are confined to the arms of a galaxy, i.e. objects that only exist within the spiral arms, and are not found (except very rarely) outside of spiral arms. Examples of tracers are structures to do with star formation, like for example open star clusters, giant molecular clouds or supernova remnants.
It is called the local spur arm. as we are not directly on the arm of a galaxy just between the sagittarius and perseus arms.
Such a galaxy is called a spiral galaxy.
Milky Way: Arms extend from a core full of black holes Elliptical Galaxy: Contains mostly older stars with a red color Irregular Galaxy: Contains dust, gas, and young stars Apex :)
Yes, there are. Most large galaxies, for example the Andromeda Galaxy or our own Milky way, have a supergiant black hole at their core. Now, in the arms of our galaxies there are thousands of black holes. So, yes, black holes do exist in galaxies. Theoretically, a black hole cannot form outside of a galaxy, because to form a black hole you require either one or two superstars, and superstars do not form outside of a galaxy or a cluster of stars.
The Milky Way Galaxy is either a spiral galaxy or a "barred spiral" galaxy in which the spiral arms (vaguely similar to a pinwheel) extend out from the "bar". In either event, the Sun and our solar system are about 2/3 of the way out along one of the spiral arms, and about 65,000 light years from the center of the galaxy.
Yes. All galaxy objects revolve around the centre of mass, which we believe is a massive black hole.
a spiral galaxy
Elliptical galaxies.
A spiral galaxy.
It has no spiral arms.
A spiral galaxy nucleus contains a mass of stars in a "bulge" and is thought that many contain supermassive black holes at the very core of the nucleus.-In galaxies with tightly wound spiral arms the bulge generally contains old, red stars with low metal content (called population II stars); whereas galaxies with more loose arms generally have younger, blue stars (called population I stars). Some bulges have similarities to the elliptical galaxies and others are similar to disk galaxies.-Evidence of supermassive black holes have been discovered in many galaxies and theorized to exist in many more galaxies (at least the larger ones). Our own Milky Way Galaxy contains a supermassive black hole at its core.
The galaxy is spinning in the direction the arms are pointing; the arms are not trailing behind.
A spiral galaxy or barred galaxy, the milky way is one.
