Pillars of Creation - Taken in 1995 by Hubble Telescope, forming in Eagle Nebula light years away. And it's about 4 light years tall! Personally, one of the most beautiful, inspiring and fascinating images I've ever seen :).
This is a composite image of the brightest supernova remnant in optical light in the Large Magellanic Cloud. The Chandra X-ray image (blue) shows million-degree gas in the center. Much cooler gas at the outer parts of the remnant is seen in.
in the LMC - Southern part of the spectacular H II region in the Large Magellanic Cloud. The green color indicates areas that are particularly hot. The field measures x square arcminutes. North is up and East is left.
