Full Answer

The Andromeda galaxy is the closest spiral galaxy to the Milky Way and can be seen with the naked eye. It is also one of the brightest objects in the sky, with an apparent magnitude of 3.4. The Andromeda galaxy has roughly the same mass as the Milky Way but contains twice the number of stars, estimated at around one trillion. Astrologists predict that in 3.75 billion years, the Andromeda Galaxy will collide with the Milky Way, forming a large, elliptical galaxy.

  • Q:

    How does a lenticular galaxy differ from a normal spiral galaxy?

    A:

    The primary difference between lenticular and spiral galaxies lies in the presence or absence of spiral arms around the galaxy's central bulge. According to the Sloan Digital Sky Survey, spiral galaxies have two distinct regions, a large central bulge and the outlying spiral arms. Lenticular galaxies also have a central bulge, but their outlying stars are less organized and more diffuse.
