Posted on 07/10/2014 8:36:47 PM PDT by SunkenCiv
Explanation: What if we X-rayed an entire spiral galaxy? This was done (again) recently by NASA's Chandra X-ray Observatory for the nearby interacting galaxies known as the Whirlpool (M51). Hundreds of glittering x-ray stars are present in the above Chandra image of the spiral and its neighbor. The image is a conglomerate of X-ray light from Chandra and visible light from the Hubble Space Telescope. The number of luminous x-ray sources, likely neutron star and black hole binary systems within the confines of M51, is unusually high for normal spiral or elliptical galaxies and suggests this cosmic whirlpool has experienced intense bursts of massive star formation. The bright cores of both galaxies, NGC 5194 and NGC 5195 (right and left respectively), also exhibit high-energy activity. In this false-color image where X-rays are depicted in purple, diffuse X-ray emission typically results from multi-million degree gas heated by supernova explosions.

This is not the image I see on APOD.
Is something wrong ?
The image is way over processed, but very pretty...
51 is nice place...I’ve been there.
I see the reason now.
Your entry is from JUNE, not JULY.
It is cool to see the switch to the x-rays by mousing over the pic. The technology to ‘see’ what we cannot ‘see’ is amazing.
Uh-oh. Guess my search and replace wasn’t too replace-y.
I spent much of the last day fiddling with a Whirlpool.
Turns out is was a faulty Wig-Wag.
I kid you not. It looks like;
except in the picture above it is turned upside down from how the device is oriented in the washing machine.
...thirty bucks or so...and the thing should be good for a few more years I think.
Symptom. Machine fills, agitates, drains, but does not "spin".
One of the two barrel shaped (black colored in the photo) solenoids gave up the ghost. Crossing a couple of wires, then testing it in "spin" cycle made the agitator function.
That indicates the non-functioning side was indeed being energized, and isolates from "timer" malfunction and potential lid switch problems too. Of course I had already gone to the trouble of bypassing the lid switch -- but given all the other conditions, the test results did isolate the problem to the one solenoid, with that being confirmed by lack of continuity using a Volt/Ohm meter, while the other solenoid (the agitator side -- which was still functioning) gave enough resistance (ohms) but not too low as in shorted, while the "spin" solenoid having none at all -- showed a break.
I never get tired of these.
No WAYS Tahrd.
I have a long dress, the colors of which are actually the same as M51’s. It is one of my favorite dresses.
M51 and the dress are both very pretty.
