2015, if you weren't aware, is the United Nations' International Year of Light. It is a global recognition of the importance that light plays in our world, from science to technology.
With hundreds of partners on board to help spread the message, NASA has led the charge with some stunning new images from its Chandra X-ray telescope.
The images are a complex tapestry of different wavelengths, both visible and non-visible which when combined, create a view of space that is unlike anything else.
By adding Chandra's X-ray images with those captured by Hubble and others, you can see the true effect that an exploding star has on a region of the galaxy.

When a massive star exploded in the Large Magellanic Cloud, a
satellite galaxy to the Milky Way, it left behind an expanding shell
of debris called SNR 0519-69.0. Here, multimillion degree gas is seen
in X-rays from Chandra (blue). The outer edge of the explosion (red)
and stars in the field of view are seen in visible light from Hubble.

This galaxy, nicknamed the "Whirlpool," is a spiral galaxy,
like our Milky Way, located about 30 million light years from Earth.
This composite image combines data collected at X-ray wavelengths by
Chandra (purple), ultraviolet by the Galaxy Evolution Explorer (GALEX,
blue); visible light by Hubble (green), and infrared by Spitzer (red).

When X-rays, shown in blue, from Chandra and XMM-Newton are joined in this image with radio data from the Australia Telescope Compact Array (pink) and visible light data from the Digitized Sky Survey (DSS, yellow), a new view of the region emerges. This object, known as MSH 11-62, contains an inner nebula of charged particles that could be an outflow from the dense spinning core left behind when a massive star exploded. (

This galaxy, at a distance of some 700 million light years, contains a giant bubble filled with hot, X-ray emitting gas detected by Chandra (blue). Radio data from the NSF's Very Large Array (red) reveal "hot spots" about 300,000 light years out from the center of the galaxy where powerful jets emanating from the galaxy's supermassive black hole end. Visible light data (yellow) from both Hubble and the DSS complete this view. (

This supernova remnant is the remains of an exploded star that may have been witnessed by Chinese astronomers almost 2,000 years ago. Modern telescopes have the advantage of observing this object in light that is completely invisible to the unaided human eye. This image combines X-rays from Chandra (pink and blue) along with visible emission from hydrogen atoms in the rim of the remnant, observed with the 0.9-m Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory (yellow).
