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?

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.
