The composite image on the left shows an image from NASA's Chandra X-ray Observatory in purple and an optical image from the European Southern Observatory's Very Large Telescope (VLT) in red, blue and white. The Chandra source in the center of the image is the ancient pulsar PSR J0108-1431 (J0108 for short), located only 770 light years from us. The elongated object immediately to its upper right is a background galaxy that is unrelated to the pulsar. Since J0108 is located a long way from the plane of our galaxy, many distant galaxies are visible in the larger-scale optical image.
The press and image releases from the Chandra X-ray Center cover only a small fraction of the science results produced by Chandra each year. Some results are clearly not good candidates for publicity because they're obviously incremental - I've written papers like that myself. Or they can be highly esoteric, addressing questions that only the authors knew enough about the subject to ask!
Dr. Muno uses Chandra to study the black holes and neutron stars that are left behind when the largest stars exhaust their fuel and collapse. Read the blog
