Astronomy: Hand of God Nebula



From Denny: This cosmic hand sure is a curiosity! The photo was captured by Nasa's Chandra observatory, circling 360 miles above our Earth. The task of this orbiting observatory is to take photos of events in our universe like the remnants of exploding stars.

This Hand of God Nebula is quite spectacular to view. It is also 17,000 lights years away from us and was produced by the pulsar B1509.

The outstretched fingers on the hand were actually produced by the spinning of a neutron star. The neutron star is known as a pulsar. This pulsar is buried deep inside the fist area and as it rotates it releases energy to create this look.

Get this: the pulsar itself is only 12 miles in diameter yet it produces the nebula to stretch across 150 light years of space!

What's a neutron star? These beauties are created when regular stars run out of fuel, collapsing. NASA seems to think that this nebula is rotating around at seven times a second.

Yeah, so explain those golden red lights. The lights are produced by a neighboring gas cloud. The gas cloud was energized by the pulsar's wind of electrons and ions spit out.

And the colors of this image represent what exactly? They represent different energy intensities: blue lights are the areas of highest energy X-rays, followed by the green and then the red.

This cosmic hand gives new meaning to the old saying, "God will get you for that!" :)

Astronomy: Butterfly Nebula



From Denny: This week, Sept. 9, NASA's been releasing new Hubble Telescope photos taken since those billion dollar repairs of the Telescope in May. The new photos are sharper of awesomely beautiful nebulas and galaxies in our universe, some with halo effects of light.

The Butterfly Nebula is known by other names such as the Bug Nebula and proper - and boring - catalogue name of NGC 6302. The Butterfly Nebula is in our own Milky Way Galaxy! It's approximately about 3,800 light years away in the constellation of Scorpius.

How did this nebula get that cool looking glowing effect on its outer edges? Photoshop, cosmic level? No, it's caused by a glowing gas that's being expelled out over 2,200 years! Quite the spectacular view from our perspective.

The butterfly shape stretches out over two light years. How do you envision the distance of two light years? It's about half the distance from the Sun to the nearest star, Alpha Centauri.
