Nasa's photo art is out of this world!

If you are interested in space and all the unkown that goes with it, you could add Astronomy Picture of the Day to your bookmarks for a daily feast of photography that is literally out of this world. Each day NASA bring a different image or photograph of our fascinating universe, along with a brief explanation written by a professional astronomer.

Today's stunning digital view, entitled 'Sagittarius Triplet', is actually a collaborative composite recorded by 2 cameras and 2 telescopes about 2 thousand miles apart! The deep, wide image field was captured under dark Arizona skies. Both M8 and M20 were recorded in more detail from an observatory in Pennsylvania. Glowing hydrogen gas creates the dominant red color of the emission nebulae, with contrasting blue hues, most striking in the Trifid, due to dust reflected starlight. These three bright nebulae are often featured in telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way.

And how about this for incredible stats - all three nebulae are stellar nurseries about five thousand light-years or so distant. The expansive M8, over a hundred light-years across, is also known as the Lagoon Nebula.

NASA certainly has the technology to shoot some incredible images that reach deep into space. Their telescopes and observatories are so advanced these days that they can - excuse me, just had to get it in - boldly go where no man has gone before! Forget pictures of the moon, head over to APOD and see what lurks in the far reaches of our galaxy :-)
