NASA just released a new gallery of images that meld X-ray data from the Chandra X-Ray Observatory with other observations made by instruments like the Hubble Space Telescope. The result is a slew of brilliant photos showing off old objects in a form that we’ve never seen before. And the images are a tantalizing taste of what we can expect in the coming years once the James Webb Space Telescope and other new instruments begin their science missions in earnest. The new photo gallery depicts five images astronomers have studied for decades, but the X-ray data helps to illuminate features that are invisible through more conventional observations. Above, you can see a picture of Cassiopeia A, a supernova remnant 11,000 light-years away. X-rays reveal different concentrations of elements like silicon (red), sulfur (yellow), calcium (green), and iron (light pu . . . read the full article here.
