Posted on 06/10/2014 1:56:23 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.

Who signs the HIPAA forms ;?
What part of the sky is this? What are some near stars or planets?
It’s in the constellation Canes Venatici close to the border of Ursa Major. It’s basically just south of Alkaid in declination. Too dim to see by eye though, you need optical assistance.
Hmmm... A galaxy walking its puppy. How sweet.
That is quite a leash.
You took that?? Wow, fantastic.
I used to dabble w/ a 12” but never came close to that.
I really get a kick out of these NASA photos. Here’s some NASA photos you won’t see:
Yup, I took that with an SBIG ST-2000XCM and 8” LX200 (with an f/6.3 reducer).
Here's a map. Just off the last star of the handle of the Big Dipper.
I understood the 8” part.:)
A very accurate clockdrive.
I see maybe several other galaxies, clouds, clusters in the pic, waaaay beyond the M 51. One at about 4 o’clock. Faint fuzzy blue dot.
My hat’s off, excellent photo.
Unfortunately, your picture doesn’t load for me
