Last July, NASA released this wonderful composite image of the galactic center of the Milky Way.
The central region of our galaxy, the Milky Way, contains an exotic collection of objects, including a supermassive black hole weighing about 4 million times the mass of the Sun (called Sagittarius A*), clouds of gas at temperatures of millions of degrees, neutron stars and white dwarf stars tearing material from companion stars and beautiful tendrils of radio emission.
The region around Sagittarius A* is shown in this new composite image with Chandra data (green and blue) combined with radio data (red) from the MeerKAT telescope in South Africa, which will eventually become part of the Square Kilometer Array (SKA).
Read more about the Chandra X-ray Observatory and it's 20th anniversary, also celebrated last July.

My God, it's full of stars!
To create this unprecedented view of the Milky Way, ESO combined thousands of individual images from VISTA, taken through three different infrared filters, into a single monumental mosaic. These data form part of the VVV public survey and have been used to study a much larger number of individual stars in the central parts of the Milky Way than ever before. Because VISTA has a camera sensitive to infrared light it can see through much of the dust blocking the view for optical telescopes. The results are truly mesmerizing!

Recent revised estimates upping the number of galaxies in the universe seem even more mind-boggling when contemplating this image released from Hubble this week. It shows NGC 362, one of about 150 globular clusters on the outskirts of just one galaxy, our own Milky Way. Read the rest
Astronomers at Caltech have created the most detailed computer simulation yet of how our Milky Way galaxy was formed, from inception billions of years ago as a loose collection of matter to its modern state as a massive, spiral disk of stars. Read the rest
