Composite image of NGC 6946, a spiral galaxy 22 million light years from Earth. At least eight supernova have exploded in this galaxy in the past century, including three spotted by Chandra (purple). Optical data is also visible in red, yellow and cyan from the Gemini Observatory. Credit: X-ray: NASA/CXC/MSSL/R.Soria et al, Optical: AURA/Gemini OBs
Fluorescent and Starry: New Zinger Space Images From Chandra’s X-Ray Archives
You know that moment when you’re flipping through old digital pictures (on your computer or phone or whatever) and you realize there are some pretty awesome ones in there that you should share on social media? The Chandra X-Ray Observatory team also decided to plumb THEIR archive of astrophysical image magic, and came up with several beauties. Such as the one above this text.
Chandra has been in space since July 23, 1999 — yes, that’s well over 14 years ago — and is considered one of NASA’s telescopes under the “Great Observatories” programs. The other telescopes, by the way, are the Hubble Space Telescope, the Compton Gamma-Ray Observatory and the Spitzer Space Telescope. Hubble and Spitzer are also still active today.
Check out more from the new set of images below. There are eight all told, representing a tiny fraction of the unprocessed thousands of images available to the public in the Chandra Source Catalog.
The Elephant Trunk Nebula (IC 1396A) in X-ray, optical and infrared light. Astronomers believe they are seeing winds from large, young stars hitting cooler gas around it, possibly triggering new starbirth. X-ray data from Chandra is in purple, with optical data (red, green and blue) and infrared (orange and cyan). Credit: X-ray: NASA/CXC/PSU/Getman et al, Optical: DSS, Infrared: NASA/JPL-Caltech3C353 looks a bit like a tadpole. In the center of this image is a galaxy powered by a supermassive black hole, which is transmitting energy across the expanse. Radiation is visible in X-rays from Chandra (purple) and radio from the Very Large Array (orange.)

Chandra’s observations (purple) revealed that the explosion seen here was likely from a star’s central core collapse. Infrared data from the 2MASS survey is also visible in red, green and blue.

This galaxy is similar to the Milky Way, but has a more active supermassive black hole in the center (visible in white). Chandra X-ray data is in blue, overlaid on European Space Observatory optical information.

It’s possible that the shape comes from heated remains of the star’s shell bump into cooler gas surrounding it. X-ray data from Chandra is purple, infrared data from the Spitzer Space Telescope is yellow, and optical data from the Digitized Sky Survey is in red, green and blue.

Chandra spotted evidence of strong winds coming from young stars in the nebula. Optical data from the European Space Observatory is shown in orange and yellow. Credit: X-ray: NASA/CXC/Penn State/L.Townsley et al, Optical: ESO/2.2m telescopeG266.2-1.2 in X-ray (purple) and optical light. Chandra spotted high-energy particles shooting out from this supernova leftover. The optical data comes from the Digitized Sky Survey and is available in red, green, and blue.

Thank you Elizabeth for the multi spectra reporting! MOST of these data the images portray were unimaginable, not that long ago.
Does the X-ray data cover the whole field in the 3C 397 image? The lit region seems to have strangely straight bottom and sides, and there’s nothing outside it. It may be real but it doesn’t look right from where I’m sitting.
The Chandra ACIS detector has a FOV of ~17’x17′. A paper describing the Chandra observations of 3C 397 ( http://arxiv.org/pdf/astro-ph/0407121v2.pdf ) notes the diffuse x-ray emission is 2.’5×4.’5 in extent, easily covered by the ACIS detector.
Thanks. So it’s real. Still looks weird, and not quite natural to me. Cheers.
