Hardly a Dwarf, Certainly Irregular

(http://apod.nasa.gov/apod/ap080409.html)

Is this a spiral galaxy? No. Actually, it is the Large Magellanic Cloud (the LMC), the largest satellite galaxy of our own Milky Way Galaxy. The LMC is classified as a dwarf irregular galaxy because of its normally chaotic appearance. In this deep and wide exposure, however, the full extent of the LMC becomes visible. Surprisingly, during longer exposures, the LMC begins to resemble a barred spiral galaxy. The Large Magellanic Cloud lies only about 180,000 light-years distant towards the constellation of Dorado. Spanning about 15,000 light-years, the LMC was the site of SN1987A, the brightest and closest supernova in modern times. Together with the Small Magellanic Cloud (SMC), the LMC can be seen in Earth's southern hemisphere with the unaided eye.

You may not wish to post this, but you might find the comment thread at this post of interest. It's all about me and my evil deed of taking the gospel to 'Indians'.

Rita, I examined that blog and the 43 comments before deciding to post yours, here.

What a maroon Renegade is! And that Larry (hey, he had supper with a Venezuelian!)- what high intelligence. Where he laments that there are so few indigenous peoples untouched by European religion, I busted out laughing..

Thank you for the big laugh just now~!

The space site is cool isn't it? They update it quite often, it is nice to sit down with a cup of Joe, stare at it and wonder about the infiniteness of it all, isn't it?

Hi, Mr. Smith!
Yeah, APOD is a cool site with daily pictures of our universe.
This, along with 'SpaceWeather . com' is a daily trek.
Along with 'Creative Endeavors'.
