What are the 4 types of galaxy classification?
Edwin Hubble invented a classification of galaxies and grouped them into four classes: spirals, barred spirals, ellipticals and irregulars. He classified spiral and barred spiral galaxies further according to the size of their central bulge and the texture of their arms.
What type of galaxy is M61?
A member of the Virgo Cluster of galaxies, M61 is roughly 55 million light-years away from Earth and has an apparent magnitude of 10.2. It is most easily spotted during the month of May and can be observed using a moderately sized telescope. M61 is a type of galaxy known as a starburst galaxy.
What type of galaxy is M77?
Seyfert galaxy
M77 is a prime example of a Seyfert galaxy, or a galaxy with an intensely active center that is obscured by gas and dust in visible light.
What type of galaxy is M83?
spiral galaxies
Also known as the Southern Pinwheel, this galaxy is located 15 million light-years away from Earth in the constellation Hydra. It was discovered in 1752 by the French astronomer Nicolas Louis de Lacaille. With an apparent magnitude of 7.5, M83 is one of the brightest spiral galaxies in the night sky.

Is Cetus a galaxy?
Cetus A), a barred spiral galaxy located 47 million light-years from Earth in the constellation Cetus. Measuring some 170,000 light-years in diameter, it is one of the largest galaxies included in the Messier Catalog. Its size and bright core also make it relatively easy to spot with binoculars or small telescopes.

What does M83 look like?
M83 is a barred spiral galaxy, likely similar in structure to our own Milky Way. Knots of red hydrogen-alpha light mark star-forming regions in this visible-light view. M83 is often cited as a close match to how our own Milky Way might appear from afar — though it’s only half as big, about 40,000 light-years across.
What does M83 stand for?
galaxy Messier 83
The name M83, to clarify, is not some Gallic street parlance or “txt” speak that’s lost in translation, it comes from the spiral galaxy Messier 83.
