An image released by the Gemini Observatory brings into focus a new and remarkably detailed view of supersonic “bullets” of gas and the wakes created as they pierce through clouds of molecular hydrogen in the Orion Nebula. The image was made possible with new laser guide star adaptive optics technology that corrects in real time for image distortions caused by Earth’s atmosphere.
The bullets are speeding outward from the cloud at up to 400 kilometers (250 miles) per second. This is more than a thousand times faster than the speed of sound. The name “bullet” is somewhat misleading since these objects are truly gigantic. The typical size of one of the bullet tips is about ten times the size of Pluto’s orbit around the Sun. The wakes shown in the image are about a fifth of a light-year long.
Clouds of iron atoms at the tip of each bullet glow brightly (blue in the Gemini image) as they are shock-heated by friction to around 5000°C (9,000°F). Molecular hydrogen, which makes up the bulk of both the bullets and the surrounding gas cloud, is destroyed at the tips by the violent collisions between the high-speed bullets and the surrounding cloud. On the trailing edges of the bullets, however, the hydrogen molecules are not destroyed, but instead are heated to about 2000°C (4000°F). As the bullets plow through the clouds they leave behind distinctive tubular wakes (colored orange in the Gemini image). These wakes shine like bullet tracers due to the heated molecular hydrogen gas.
And you think first-person-shooters rock? Get your brain around these critters.
Now, everyone pony up $0.50 so we can go fix the Hubble. We need the WFPC2 (Wide field planetary camera) back.
From photonics.com:
In one of the most detailed astronomical images ever produced, NASA’s Hubble Space Telescope captured an unprecedented look at the Orion Nebula. This turbulent star formation region is one of astronomy’s most dramatic and photogenic celestial objects.

1, Whoops, I meant to say the ACS (Advanced Camera for Surveys), it’s the old WFPC2 now doing all the work. If we’re lucky, NASA will repair it and additionally install the WFC3.
The ContentLink over the “Hubble Space Telescope” is amusing. Apparently, I can “Compare & Save.”
FSBO – Hubble Space Telescope. Used, one owner. Needs minor repair.
Ever since I got my fist Internet connection back in 95, I’ve been
staring at photos like these. The dimensions are truly mind-blowing!
I sometimes get that warm feeling around my Amygdalas, when I try to
comprehend the infinite space in these images. I would love to share the
-Best of Hubble- prints with the war-torn areas of the world [if I could
afford it] I think seeing such images would make people stop and think for a second about the big picture. Maybe?
It truly is, the thinking man’s pornography! ..Thanks Dvorak!
I’m as blown away as anybody when it comes to deep space imagery, and the Einstein thought processes these images trigger, but somehow the thought of speeds being expressed relative to the speed of sound at the bottom of our atmospheric soft shell is disturbing. The term “supersonic” really doesn’t mean much in airless space; it’s kind of like all these supposedly scientific shows on Discovery, etc, where asteroids go “whooshing” along in airless space.
So how does Jesus tie into all this?

Darn it, I forgot to mention to be sure to click on the ‘bullets rip’ link on the APOD for 03.26.2007.

“So how does Jesus tie into all this?”
Funny, I was just wondering why our right honorable friends who elsewhere persist in contending that “science is nothing but faith / dogma” and other such slackjawed idiocies are so conspicuously absent in every thread that addresses scientific progress…
I guess they’re comfortable just using the fruits of it. 😉
