What is galaxy NGC?
The acronym NGC stands for “New General Catalogue” and usually precedes a number in the catalogue, like NGC 4258 for example. The catalogue refers to objects which are extended and distinctly non-star like in nature. NGC 1300, a barred spiral galaxy is an example of a typical NGC catalogue entry.
Is NGC 1705 forming stars?
At 17 million light-years away, the individual stars of the dwarf irregular galaxy NGC 1705 are out of range of all but the sharp eye of Hubble. This galaxy has been forming new stars throughout its lifetime, but a burst of star-formation activity occurred as recently as 26 to 31 million years ago.
How old is NGC 6946?
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.
What does M NGC and IC mean?
November 12, 2013 at 6:44 AM · NGC, M and IC. What do they mean? These letters are abbreviations for astronomical catalogues of known stars, nebulae, supernova remnants, galaxies and other objects in space.
Are galaxies close together?
I heard yesterday that relative to their size, galaxies are much closer together than stars. Just using orders of magnitude, the sun is 109 meters wide and the nearest star is 1016 meters away. The Milky Way is 1021 meters wide, and the Andromeda galaxy is 1022 meters away.
How many visible galaxies are there?
Subsequent sensitive observations such as Hubble’s Ultra Deep Field revealed a myriad of faint galaxies. This led to an estimate that the observable universe contained about 200 billion galaxies.
