other galaxies?

Question

Are there other galaxies known that are usually not written in textbooks? I need that for my report.

Answer 1

Just read this:

Answer 2

Most definitely,
As a matter of fact, the typical text books usually describe only the most commonly known Galaxies or those of some particular interest, such as for a research project.
Also, new galaxies are discovered all the time.
The most up to date listings of galaxies are found in various catalogs.
One of the more interesting ones is AARP"S list of peculiar Galaxies, The NGC catalog and those found in the Herschel Catalog. Although not strictly a list of Galaxies, the Messier list contains a number of them.
Although there are dozens of catalogs with tons of entries, the ones mentioned above contain more dtailed info, besides just the location, magnitude and class that is found for most objects in the typical catalogs.
There are searchable data bases on line, the easiest to deal with is probably the Deep Sky Survey (DSS). A google search will find it quickly enough. Besides the basic info, it has an image of all the listed objects that you can view and download. It'll take you a minute to figure out how to use it, but it's well worth the effort.

It's fairly hard to give good examples without knowing your textbooks or what exactly the report is supposed to be on (and what academic level). Here's some galaxies that are of particular scientific interest.

The Canis Major dwarf irregular should be a good start (closest know galaxy, approx. 25,000 lyr heliocentric distance; 1st link).


QSO 0957+561 might be good for being the first detected gravitational lensing pair (2nd link); Mayall II goes with that as the lensing galaxy (3rd link).

Whirlpool should be in your textbooks if they're any good, being the prototype interacting galaxy (4th link). Still, list it to be safe.

NGC 1260 won't be in any textbooks (5th link), because it's not so remarkable as a galaxy but for being the host galaxy to the unusual supernova SN 2006gy.

Answer 4

Well there are hundreds of billions of other galaxies outthere, but not a whole lot is known about them. Some scientists estimate that since there is life in our galaxy there is some probability that it also exists on others, but currently we have no way of proving or disproving it.

Answer 5

There are billions of galaxies that are not named as individuals.
The Hubble deep field research showed galaxies that had never been seen before.
90% of the galaxies visible to-day do not exist anylonger.

Answer 6

I know some of them,I'll tell you a few:


Tamhara 2X-9

Gencirenfe 30M,TT

Najtoren Hew 241

Raethaga 5-HO8

Hyperena (this one is pretty cool)

Yergax

Vakteroksen 2-13420

Figenhaga 9543 (big)

Upercender 3.0*5 (Large)


You are probably wondering how I know these galaxies.the names are cool aren't they?!

Answer 7

Hello and thank-you for this nice question.

I can help you a lot with this. Please go to astromart dot com where a lot of telescopes and parts are listed in classified ads, and a few auctions. That site has a banner headline which takes you to a site asking for people to assist in naming the new constellations which are not yet named. If
you go to that site you should find what you need for your report.

Answer 8

Yes. Most of the galaxies are currently unknown. These are so numerous that you just can count them so easily, or they are just too far and too faint to be easily seen.

Answer 9

yes ,there are other galaxies in our milky way galaxy.For more details visit http://www.google.com
