NGC 2024, The Flame Nebula, burns brightly in Orion the Hunter. At right is the brilliant blue giant star, Alnitak, 28 times the mass of our sun. Shining with a brightness 100,000 times that of the sun, Alnitak, is actually a triple star system in which two smaller blue stars orbit the behemoth. This false color image was formed from nine stacked frames of three minutes each binned 2 x 2, taken through narrow band Hydrogen alpha filter at focal length of 1480 mm, f/6.3. Image scale was 1.51. arc seconds per pixel.

Astronomy Quote of the Day

“I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars.” Stephen Hawking
