Seeing the Universe
You can see what x-ray astronomy adds to the other wavelengths if we take a close-up look at a galaxy known as "Centaurus A."
OPTICAL: This is one of the best optical images...
In radio light these jets shoot out from the galaxy a distance about 6 diameters of our milky way galaxy!!! RADIO:
VISIBLE:
NEAR INFRARED:
Zooming further in, even Hubble's eye gets blocked by all the gas and dust
But using infrared light, Hubble can see through the dust to the hot gas researchers think is swirling around a black hole many millions of times more massive than our Sun!
"EINSTEIN" X-RAY OBSERVATORY (1979) Earlier, the "Einstein" X-ray Observatory had been able to see deep down, to where the energetic jets begin...
Now Chandra can resolve still finer details of this active galactic nucleus...
