This is a 2006 Hubble image of M101 a spiral galaxy also know as NGC 5457. If you were wondering about the catalogue letters, M stands for Messier (mess-e-a) a french guy who set up one of the first catalogues. NGC stands for New Galactic Catalogue. More M101 wiki info.



Only available in 16:10.

Full res.

If you would like to find the original pictures of what I make then check out Astronomy Picture of the Day (APOD) and Hubble's archive websites. And this link to the forum.
And of course, the Gallery.

I was wondering what the AM designation was in this post.

Found loads more info that I needed  

Apparently it means...
AM 2020–505 Peculiar galaxies (Arp, Madore) AM_HHMM±DDd

Where...
HH Hours of right ascension
MM Minutes of right ascension
DD.d Degrees in declination
and the AM is Arp, Madore the guys who did the survey I guess.

Do I need to explain right ascension/ declination?

You could link to the Wiki if its worrying you Snowy   

Rather than me waffle on about celestial spheres and such the wiki is prob the best idea.

Too much info is better than not enough in my opinion.

Good to see you back Snowy and with another of your stunning wallpapers. 

I'm quite sure somewhere on this pic, an e.t. is taking a photo of us. 

LOL, GT, I never thought of that, reckon you're right though .
