A giant lens
The picture isn't really that pretty, but it's pretty amazing when you think about it. It's using the gravity of a dense cluster of galaxies as a sort of celestial magnifying glass. The smear-like objects toward the left are more distant galaxies whose images are distorted by the gravity of the cluster. The two red dots in the inset are the same object (13 billion light years away!), shown double because the light has been bent by an intervening galaxy.
Under the right circumstances, the gravitational lens can magnify distant objects by about thirty times.

My hubby really liked that image too. He was inspired to create this work of art. This is titled Stopping by Io Enjoy!
You can find more of his marvelous artwork at MarkClarkson.com I can never resist plugging his work. I think it's great. But, I admit, I am biased about it.

What ? Are you serious ??? Can't you tell ?????
With all that noodly appendage, it's the First Son of the FSM.
Sent to cleanse us all from all that spilt pesto sauce.
Bows down ...

Aaaarrrggh! I'm having flashbacks to my undergraduate labs! I spent a hot sunny June afternoon hunched in semi-darkness over a light table, staring at image after image of particle tracks!Asm said:

Re: Re: Z machine
Z Machine
"ALBUQUERQUE, N.M. -- Researchers at Sandia National Laboratories' Z machine -- the former dark horse among accelerators meant to produce conditions required for nuclear fusion -- have increased the machine's X-ray power output by nearly 10 times in the last two years.
The most recent advance resulted in an output X-ray power of about 290 trillion watts -- for billionths of a second, about 80 times the entire world's output of electricity.
The figure represents almost a 40 percent increase over the 210 trillion watts -- itself a world record -- reported last summer.
Strangely, the power used in each trial is only enough to provide electricity to about 100 houses for two minutes. Electricity is provided by ordinary wall current from a local utility company.
Yet particles imploded in the accelerator's tiny targets -- about the size of a spool of thread -- reach velocities that would fly a plane from Los Angeles to New York in a second....."

Okay, my brain wants to see the Discovery in that image instead of the space station.My hubby really liked that image too. He was inspired to create this work of art. This is titled Stopping by Io Enjoy!
