Sonified Images
These three astronomical objects are the latest to have their data translated into sound. Data sonification converts data from telescopes into a form that users can hear instead of only see. The Chandra Deep Field represents over 7 million seconds exposure time and the deepest X-ray image ever taken. Data from Chandra and Hubble show the Cat's Eye, a phase of stellar life that stars like our Sun experience when they run out of hydrogen and helium. The Whirlpool Galaxy, seen in four different types of light, is a spiral galaxy that is similar to the Milky Way. Listen to the sonifications here.

X-ray Images of Chandra Deep Field South
Made with over 7 million seconds of Chandra observing time, this image is part of the Chandra Deep Field-South (CDF-S) and is the deepest X-ray image ever obtained. With its unprecedented look at the early Universe in X-rays, the CDF-S gives astronomers the best look yet at the growth of black holes over billions of years starting soon after the Big Bang. In the Chandra images, low, medium, and high-energy X-rays that Chandra detects are shown as red, green, and blue respectively. By combining the Chandra Deep Field with observations from other telescopes including Hubble (also shown here), scientists can continue to probe some of the most important questions in astrophysics.

X-ray & Optical Images of the Cat's Eye Nebula (NGC 6543)
X-ray emission from Chandra is colored purple and optical emission from the Hubble Space Telescope is colored red, green and blue. A planetary nebula is a phase of stellar evolution that the sun should experience several billion years from now, when it expands to become a red giant and then sheds most of its outer layers, leaving behind a hot core that contracts to form a dense white dwarf star. A wind from the hot core rams into the ejected atmosphere, creating the shell-like filamentary structures seen with optical telescopes. The diffuse X-ray emission is caused by shock waves as the wind collides with the ejected atmosphere. The properties of the X-ray point sources in the center of about half of the planetary nebulas suggest that many central stars responsible for ejecting planetary nebulas have companion stars.

X-ray, Infrared, Optical, & Ultraviolet Images of M51 (Whirlpool Galaxy)
A composite image of M51, also known as the Whirlpool Galaxy, shows a majestic spiral galaxy. Chandra finds point-like X-ray sources (purple) that are black holes and neutron stars in binary star systems, along with a diffuse glow of hot gas. Data from Hubble (green) and Spitzer (red) both highlight long lanes of stars and gas laced with dust. A view of M51 with GALEX shows hot, young stars that produce lots of ultraviolet energy (blue).
