The sender writes:
This bipolar star forming region is called Sharpless 2-106.  This picture is a December 2011 release from NASA / Hubble of a Nebula that looks like a snow angel.
The heavens declare HIS glory!

Supernova Rings from the Hubble Space Telescope

Supernova Rings
This image taken by the Hubble Space Telescope's Wide Field Planetary camera shows a mysterious pair of rings of glowing gas that surround the location of a supernova explosion known as 1987A.  The supernova is almost 170,000 light-years away.

Core of Galaxy NGC 4261
Located 45 million light-years away and estimated to be 300 light-years across, the giant elliptical galaxy NGC 4261 is one of the twelve brightest galaxies in the Virgo cluster.

The sender writes, " 300 light-years across = approx 1,76354994 X 10 (with a little 18 to the right of the 10) miles across!  WOW! that's 3 times larger than our own galaxy."

Death of a Star: Egg Nebula

The Egg Nebula is a large cloud of dust and gas ejected by the star and expanding at a speed of 115,000 miles per hour.  Such nebulae are a rare sight; they are in an evolutionary phase that lasts a very short time (1,000-2,000 years)

Atmosphere of Uranus

Atmosphere of Uranus
Infrared filters allow astronomers to probe in more detail the structure of Uranus's atmosphere, which consists mostly of hydrogen, with traces of methane.  Although the atmosphere's three layers show up as red, yellow, and blue in this image in reality the rings are as dark as black lava or charcoal.

Hubble Telescope Space Walk

Astronauts install a Fine Guidance Sensor (FGS) into a protective enclosure in the Shuttle's payload bay.  These two astronauts performed the second of three space walks to service the Hubble Space Telescope (HST) on the STS-103 mission.
