Chandra X-ray Image of M83
This X-ray image of M83 was observed on April 29, 2000 for 13 hours with the Advanced CCD Imaging Spectrometer (ACIS). Chandra observations of this spiral galaxy and 3 other nearby galaxies have revealed a possible new class of X-ray sources. These mysterious X-ray sources, marked with green diamonds in the version on the left, are called "quasisoft" sources because they have a temperature in the range of one to four million degrees Celsius.
Color Code: Energy (Red: 0.3-1.0 keV, Green: 1.0-2.0 keV, Blue: 2.0-8.0 keV)
Obs. ID: 793
Scale: 8.80 x 8.85 arcmin

Chandra X-ray Image of M51 (Whirlpool Galaxy)
This X-ray image of M51 was observed on June 20, 2000 for 4 hours with the Advanced CCD Imaging Spectrometer (ACIS). Chandra observations of this spiral galaxy and 3 other nearby galaxies have revealed a possible new class of X-ray sources. These mysterious X-ray sources, marked with green diamonds in the version on the left, are called "quasisoft" sources because they have a temperature in the range of one to four million degrees Celsius.

Chandra X-ray Image of NGC 4697
This X-ray image of NGC 4697 was observed on January 15, 2000 for 11 hours with the Advanced CCD Imaging Spectrometer (ACIS). Chandra observations of this spiral galaxy and 3 other nearby galaxies have revealed a possible new class of X-ray sources. These mysterious X-ray sources, marked with green diamonds in the version on the left, are called "quasisoft" sources because they have a temperature in the range of one to four million degrees Celsius.

Chandra X-ray Image of M101
Chandra observations of the spiral galaxy M101 and several other nearby galaxies have revealed a possible new class of X-ray sources. These mysterious X-ray sources, marked with green diamonds in the image, are called "quasisoft" sources because they have a temperature in the range of one to four million degrees Celsius.
