we need more info on the nature and cause of the X rays mentioned, if anyone knows of them or how they are related to the galaxy, add. →ubεr nεmo→ lóquï 06:08, August 8, 2005 (UTC)
I know there are already 3 photos on the page, but here is another that is from NASA (no copyright) that maybe be useful.-- Andrew c 17:59, 17 March 2006 (UTC)

Cigar Galaxy → Messier 82 – This galaxy is best known by both professional and amateur astronomers as "Messier 82" or "M82". "Cigar Galaxy" is not a well-known name and could cause confusion. George J. Bendo 14:26, 19 August 2006 (UTC)

This article ("Sky Lights: The Dark Side of the Universe" by Bob Berman, Discover Magazine, V27, No. 8) was cited as the reference.
This information is plainly wrong. First of all, the Discover article (or at least the online version) never made such a claim. Second, the solar system is already near its closest location to M82 in its orbit (according to the galactic coordinates from the NASA/IPAC Extragalactic Database); M82 will only appear to be smaller when the solar system completes another half-orbit in the Milky Way. Third, Messier 81, which is interacting with M82, is physically twice or three times as large as M82; M81 would therefore appear larger than M82 regardless of where it was viewed from. Finally, the solar system's radius from the center of the Milky Way is only ~8 kpc, whereas the distance to M82 is ~3-4 Mpc; the change in distance to M82 as the Sun orbits the Milky Way is so small that the apparent size of M82 (~11 arcmin) will hardly change.

That view of M82 is what you would get with a large (200 mm and larger) telescope under higher magnification under a clear, transparent sky (I can attest to it because I have seen it with my 12-inch Dobsonian telescope at 166X). A person with a smaller telescope would not get that type of view, instead it would look like an elongated smudge. Rwboa22 21:13, 21 March 2007 (UTC)
Why it isn't metioned at all that M82 is a powerfull radiosourse? It has a 3C, 4C, 6C and 8C number (from ned results for M82) and according to SEDS pages it is the Ursa Major A sourse. I added just the 3C number 231 and the correspoding category. -- C messier ( talk) 09:08, 7 January 2010 (UTC)
perhaps someone wants to incorporate this : http://www.newscientist.com/article/dn18775-mysterious-radio-waves-emitted-from-nearby-galaxy.html in the article somehow 80.57.43.99 ( talk) 08:49, 18 April 2010 (UTC)
Is there a reason the current lead has been chosen over this, much larger image? The question has been raised at Wikipedia:Featured picture candidates/Messier 82- the opinions of more knowledgable editors would be appreciated. J Milburn ( talk) 20:20, 15 August 2010 (UTC)
Hello! This is a note to let the editors of this article know that File:M82 HST ACS 2006-14-a-large web.jpg will be appearing as picture of the day on May 21, 2013. You can view and edit the POTD blurb at Template:POTD/2013-05-21. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 ( talk) 23:34, 4 May 2013 (UTC)
