Joe DePasquale, Science Imager for NASA's Chandra X-ray Observatory, gives a pictorial tour behind the scenes on processing our latest Chandra press release image, supernova remnant W49B
I thought it might be useful to take a quick look at the various components that went into making the image for W49B. The release has sparked some attention and discussion on black holes, as well as how (and why) images such as these are colored. The processing of W49B included a combination of Chandra's CIAO software, PixInsight and Photoshop. The colors applied are representative, as we are translating something invisible to our eyes into something we can see. The image combines X-rays from NASA's Chandra X-ray Observatory in blue and green, radio data from the NSF's Very Large Array in pink, and infrared data from Caltech's Palomar Observatory in yellow. Enjoy, and feel free to ask any questions.
This week marks a milestone in the openFITS collection as we've nearly doubled the amount of data offered up for curious minds to explore and create their own images. We now offer a collection of 17 data sets covering supernova remnants, galaxies, neutron stars, pulsars, and the supermassive black hole at the center of our very own galaxy, the Milky Way. Additionally, we've updated the openFITS overview and tutorials to reflect changes in the newest version of GIMP (v2.8), our choice of image processing platform for this project. GIMP v2.8 is now available as a native application on Mac OS X and offers some exciting new features as well as laying the groundwork for very exciting developments to come.
October is American Archives Month—a time to celebrate the importance of archives across the country. In honor of Archives Month, we're participating in a pan-Smithsonian blogathon. Throughout October we, and other blogs from across the Smithsonian, will be blogging about Chandra's rich archive of astronomical data, issues, and behind-the-scenes projects. Check out the RSS feed of blogathon posts from across the Smithsonian.
