This is a nice image of the Milky Way galaxy as seen from the NASA’s Chandra X-ray Observatory. The Milky Way galaxy is an example of a barred spiral galaxy.
This picture of the center of the Milky Way galaxy was generated by the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory. The bright white region in the image, also called Sagitarrius A was said to be the location of the black hole.
Here’s a nice artist illustration of our galaxy, Milky Way. This illustration shows the interpretation of the galaxy’s new look. As seen in the image, two arms are wrapping off the ends of a central bar of stars instead of four.
This is a nice photo of a brilliant star observed at the core of the Milky Way galaxy. This picture was obtained by the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer (NICMOS). This instrument made it possible to obtain the image since the star is hidden at the galaxy’s center.
This is a Chandra photo of the black hole located at the center of our Milky Way galaxy. The black hole is called Sagittarius A* or Sgr A*. This black hole is approximately 4 million times the mass of our Sun.
