Galaxy's Ghostly Arms Finally Explained Credit: NASA/CXC/Univ. of Maryland/A.S. Wilson et al. Optical: Pal.Obs. DSS; IR: NASA/JPL-Caltech; VLA & NRAO/AUI/NSFIn this composite image of spiral galaxy M106, optical data is shown as yellow, radio data from the Very Large Array appears as purple, X-ray data from Chandra is coded blue and infrared data from the Spitzer Space Telescope appears red. The anomalous arms appear as purple and blue emission.

This image of supernova remnant 0509-67.5 was made by combining data from two of NASA's Great Observatories. Optical data of SNR 0509-67.5 and its accompanying star field, taken with the Hubble Space Telescope, are composited with X-ray images from the Chandra X-ray Observatory.

This is a composite image of NGC 1068, one of the nearest and brightest galaxies containing a rapidly growing supermassive black hole. X-ray data from the Chandra X-ray Observatory are shown in red, optical data from the Hubble Space Telescope in green and radio data from the Very Large Array in blue. The spiral structure of NGC 1068 is shown by the X-ray and optical data, and a jet powered by the central supermassive black hole is shown by the radio data. Credit: X-ray (NASA/CXC/MIT/C.Caniz...

This is a color enhanced version of the infrared signal to make the Double Helix Nebula's features easier to see. The spots are mostly red giants and red supergiants. Many other stars are present, but are too dim to appear.

X-Ray / Optical Composite Image Of The Large Spiral Galaxy NGC 2841 - Marshall Space Flight Center (03/06/06)

Trigger-Happy Star Formation (NASA, Chandra, 8/12/09). his composite image, combining data from the Chandra X-ray Observatory and the Spitzer Space Telescope shows the molecular cloud Cepheus B, located in our Galaxy about 2,400 light years from the Earth. A molecular cloud is a region containing cool interstellar gas and dust left over from the formation of the galaxy and mostly contains molecular hydrogen.

Galactic Chimneys Turn Up the Heat (NASA, Chandra, 03/06/06) | This X-ray/optical composite image of the large spiral galaxy NGC 2841 shows multimillion degree gas (blue/X-ray) rising above the disk of stars and cooler gas (gray/optical).

Inside Cassini's Multi-Year Saturn MIssion (Infographic) by Karl Tate, Infographics Artist : Since 2004, the Cassini space probe has orbited Saturn, collecting photos and data that have revolutionized our understanding of the planet and its moons.

A million-degree plasma cloud in the Orion Nebula. The emission colored in blue shows X-ray emission from a hot plasma cloud in the extended regions of the Orion Nebula, detected by the XMM-Newton satellite. The background image has been recorded by the Spitzer Space Telescope in the infrared, showing emission from cool dust.
