What type of galaxy is NGC 253?
spiral galaxies
NGC 253 is one of the brightest spiral galaxies visible, but also one of the dustiest. Dubbed the Silver Coin for its appearance in smalltelescopes, it is more formally known as the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor.
How did Hubble measure the distance to the Andromeda Galaxy?
How did Edwin Hubble measure the distance to the Andromeda Galaxy? He applied the period-luminosity relation to Cepheid variables. From the period-luminosity relation for Cepheids, he was able to determine the distance to Andromeda and show that it was far outside the Milky Way Galaxy.
What NGC is our galaxy?
NGC 4013 is a spiral galaxy, similar to our own Milky Way, lying some 55 million light-years from Earth in the direction of the constellation Ursa Major.
How many NGC galaxies are there?
NGC 1300, a barred spiral galaxy is an example of a typical NGC catalogue entry. The New General Catalogue was originally compiled by J.L.E. Dreyer in 1888. There are some ~8,000 objects with NGC numbers.

What type of galaxy is Arp 252?
spi- ral galaxies
Image courtesy AURA/NOAO/NSF. 8) Arp 252 – The interaction between these two spi- ral galaxies has distorted their spiral arms, stretching them out into long tails. These long tails are character- istic of galaxy collisions and interactions.
How is the distance to Andromeda calculated?
Distances to deep-sky objects such as the Andromeda galaxy are often determined using what are referred to as “Standard Candles”, which means that astronomers look for objects located within the target for which they believe they know the intrinsic luminosity (how bright it actually is).
What distance method is used to calibrate galaxy distances?
The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects.

How far is the firework galaxy from the Milky Way?
The Fireworks Galaxy (NGC 6946) NGC 6946, or “The Fireworks Galaxy”, is one of about a dozen nearby neighbors to the Milky Way. It is located approximately 10 million light-years away in the Cepheus constellation.
What is NGC in space?
Any amateur astronomer who has read about the universe or has an interest in observing deep-sky objects has encountered the letters NGC. They stand for New General Catalogue. The complete title is New General Catalogue of Nebulae and Clusters of Stars.
