Who discovered NGC 7331?
Wilhelm Herschel
It is an island universe similar to our own Galaxy (or maybe somewhat larger) and placed at a distance of 50 million light-years. NGC 7331 was discovered by Wilhelm Herschel in 1784, and it shows all its magnificence in long-exposure photographs taken through large telescopes.
How old is NGC 1232?
NGC 1232 is an intermediate spiral galaxy about 60 million light-years away in the constellation Eridanus. It was discovered by German-British astronomer William Herschel on 20 October 1784. It is dominated by millions of bright stars and dark dust, in spiral arms rotating about the center.
What Type of galaxy is NGC 7331?
spiral galaxy
NGC 7331 is the brightest galaxy in Pegasus. This spiral galaxy was one of William Herschel’s earliest discoveries over 200 years ago. Although visible in large binoculars, it was missed by Messier. In many respects this galaxy resembles the famous, much-elongated, Andromeda Galaxy, M-31.
How many NGC galaxies are there?
Eleven prime NGC objects The NGC contains 7,840 objects, and there are 990 prime numbers within that range. By far, most are galaxies. The fewest of any type — five — are planetary nebulae. I have selected a prime number of these, 11, for your observing pleasure.

How old is JKCS 041?
Peering back to a time when the galaxies in JKCS 041 were only 1 billion years old — or 10 percent of their present age — the team found that most had already entered their quiescent phase.
Which spiral galaxy is oldest?
The most ancient spiral galaxy found so far, called BRI 1335-0417, at an distance of 12.4 billion light-years and at a time just 1.4 billion years after the Big Bang. Spiral arms are visible on both sides of the compact, bright area in the galaxy center.
