What are the primary Catalogues we use to keep a record of deep sky objects?
The Messier and NGC catalogues are undoubtedly the most famous astronomical references for deep-sky objects.
Does the Milky Way have an NGC number?
NGC 6946 lies within the Virgo Supercluster. Discovered by William Herschel on 9 September 1798, this well-studied galaxy has a diameter of approximately 40,000 light-years , about one-third of the Milky Way’s size, and it contains roughly half the number of stars as the Milky Way.

Why are galaxies called NGC?
For example, NGC 7331, a galaxy that has been called a twin of the Milky Way because of its similarity. The NGC catalog is short for New General Catalogue, and it’s a list of 7,840 interesting objects in the night sky. Many galaxies are named after the constellation they’re located in.
What means NGC?
What is deep space astronomy?
Deep space exploration (or deep-space exploration) is the branch of astronomy, astronautics and space technology that is involved with exploring the distant regions of outer space. However, there is little consensus on the meaning of “distant” regions. In some contexts, it is used to refer to interstellar space.
What counts as a deep sky object?
Deep-sky objects are celestial objects that exist outside our solar system. Three major types of deep-sky objects are nebulae, star clusters, and galaxies. The word nebula is Latin and means “cloud.” A nebula (plural = nebulae), therefore, is a cloud of gas and dust in space.
What is NGC 1 and where is it located?
NGC 1, also occasionally referred to as GC 1, UGC 57, PGC 564 or Holm 2a is an intermediate spiral galaxy of the morphological type Sbc, located approximately 210 to 215 million light-years from the Solar System in the constellation Pegasus.
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.
What is NGC rating?
The NGC Rating expresses a vehicle’s environmental impact as a score ranging from 0 for the greenest vehicles to 100+ for the most polluting. The NGC Rating was developed by Next Green Car and is a unique method of assessing and comparing the environmental impact of a vehicle.
