A spiral galaxy located about 30 million light years from Earth.
{"Image ImageDescription": "This image contains nearly a million seconds worth of Chandra observing time (purple) along with optical data from the Hubble Space Telescope (red, green, and blue).  The X-ray data reveal hundreds of point-like sources, most of which are X-ray binary systems (XRBs) containing a neutron star or black hole in orbit with a star like the Sun.  Researchers are studying the XRBs in M51, a.k.a. the \"Whirlpool Galaxy,\" to better understand the role they play in the evolution of the galaxy.", "Image Orientation": "Horizontal (normal)", "Image XResolution": "72", "Image YResolution": "72", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "Adobe Photoshop CS6 (Macintosh)", "Image DateTime": "2014:05:15 14:24:10", "Image Artist": "Chandra X-ray Observatory Center", "Image ExifOffset": "168", "Thumbnail Compression": "JPEG (old-style)", "Thumbnail XResolution": "72", "Thumbnail YResolution": "72", "Thumbnail ResolutionUnit": "Pixels/Inch", "Thumbnail JPEGInterchangeFormat": "318", "Thumbnail JPEGInterchangeFormatLength": "5102", "EXIF ExifVersion": "0221", "EXIF ColorSpace": "sRGB", "EXIF ExifImageWidth": "572", "EXIF ExifImageLength": "864"}
