Did you see this Image of the Day at the NASA site?
This is another of those collaborative efforts in the astronomical community. I think they set a good example.
So the caption that came with the image (below) explains it pretty well. I usually try and sort out what is going on before reading the real story, happy to say I’m getting pretty good at it. LOL.
Oh, you can get different sizes at the NASA IOTD site.
This composite image of a galaxy illustrates how the intense gravity of a supermassive black hole can be tapped to generate immense power. The image contains X-ray data from NASA’s Chandra X-ray Observatory (blue), optical light obtained with the Hubble Space Telescope (gold) and radio waves from the NSF’s Very Large Array (pink).
This multi-wavelength view shows 4C+29.30, a galaxy located some 850 million light years from Earth. The radio emission comes from two jets of particles that are speeding at millions of miles per hour away from a supermassive black hole at the center of the galaxy. The estimated mass of the black hole is about 100 million times the mass of our Sun. The ends of the jets show larger areas of radio emission located outside the galaxy.
