How many and what are the other know galaxies besides the milkyway and andromeda?

Question

Ok this is kind of two questions

can anyone tell me how many know galaxies are out there, and some of there names. The ones i know are the milkyway (duh!) and andromeda

Answer 1

There are literally billions of known galaxies. Most of them have rather uninteresting designations. But there are a few that have 'common names' such as the Whirlpool galaxy, the Blackeye galaxy, the Sombrero galaxy, the Antenae galaxies, Stephen's quartet, etc. More have 'Messier' designations (Messier was a comet hunter and catalogued a number of 'fuzzy' objects). Another desgination for the Andromeda spiral is M31 for Messier 31. The Whirlpool is M51. Several of the Virgo cluster of galaxies are in the Messier list. After that, many of the nearer galaxies have NGC designations (from the catalog name); for example NGC 6561 is a nice spiral. Farther out, the galaxies tend to be specified by their place in the sky.

Answer 2

Probably the oldest galaxy yet found, IOK-1, was discovered in September 2006 by Masanori Iye at National Astronomical Observatory of Japan using the Subaru Telescope in Hawaii. Its emission of Lyman alpha radiation has a redshift of 6.96, making it thirteen billion years old. While some scientists have claimed other objects (such as Abell 1835 IR1916) to be even older, the IOK-1's age and composition have been more reliably established

Answer 3

Well, as someone has said, there are billions, and some do have names that have been given (usually due to an unusual shape or brightness)
The ones that come to mind most readily are the Blackeye (so named because if the large cloud of dust which obscures part of its nucleus), the Whirlpool (because it is seen face on and is the best example of a spiral galaxy) the Sombrero (obviously because it looks like one), the Ring Galaxy (which appears as a simple ring, the result of a galactic collision many billions of years ago) and of course the Magellanic clouds that are in the southern hemisphere (both are irregular galaxies). Add these to your own list and you have a good start. Perhaps someone will add a few more?

Answer 4

There are hundreds if not thousands of galaxies in the catalog. Most are just numbered, some are named (such as the Sombrero Galaxy for example). The primary viewable's are the "Messier" objects, denoted with an "M" like M17 or M39 you also have the NGC and the IC as well.

Here is a link to many catalogs There are MANY different types of galaxies, from spiral's to globular clusters. Check'em out!

Answer 5

The total number of observable galaxies is estimated to be around 100 billion, based on what was seen in the various Hubble deep field images.

The largest catalog of galaxies is the SDSS (Sloan Digital Sky Survey) catalog, the first installment of which lists 200 million objects, most of them galaxies. They have also taken spectra of 675,000 galaxies.

As for named galaxies, another list is at http://www.iitk.ac.in/ac/right/util/naga.htm . It's got some that aren't on the Wikipedia list, though it's also missing some from that list.

Answer 6

well,i can't tell u how many galaxies are out there coz,the universe is expanding and more galaxies are formed this very minute.but i can assure u there are lots,LOTS of galaxies out there.do u know the Hubble telescope?if u don't,it's a telescope created by Edwin Hubble.this telescope helped us to look far beyond our galaxy,like the Horsehead nebula and many more.the furthest pic that hubble can get is called 'Hubble Deep Field'.u can look it up in the internet if u want to.

the galaxies i know other than milky way is the Tadpole, Cartwheel, Spider, Antennae, Barbon, Barnard, Bears Paw, Black Eye, Carina Dwarf, Circinus, Draco Dwarf,Helix, Lost, Pancake,Pegasus Dwarf,Pinwheel, Sunflower, Small Magellanic Cloud, Ursa Minor,and Silver Coin. There are many more out there,believe me.

Answer 7

Part of your question can't be answered ,,,, A solar system is made up of planets a galaxy is made up of solar systems,,,,, Untold numbers of galaxies make up the universe ,,,,the universe is believe to be infinite ,,,, As far as I know ,,,, other than our own galaxy the Milky Way and the one next to us ,,,, The Andromeda Nebula little else is really know ,,,, Man has his hands full just studying our own galaxy and the Andromeda Nebula as it is ,,,,,

Answer 8

The estimated number of galaxies is in the order of billions.
Here's a list of galaxies:

Answer 9

if you go to http://www.shatters.net/celestia/
you can get a free astronomy program.
once you have installed that, go to:
http://www.lepp.cornell.edu/~seb/celestia/galaxies.zip
there you will find a file that will show you 1,825 cataloged galaxies.
so far we have only cataloged 131.601 galaxies, even though there are millions of millions.

Answer 10

There are about 100 billion galaxies, but sorry I don't know all their names!!
