  APOD: 2018 January 22 - An Immersive Visualization of the Galactic Center

                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: What if you could look out from the center of our Galaxy -- what
might you see? Two scientifically-determined possibilities are shown in the
featured video [6] , an immersive 360-degree view which allows you to look
around in every direction. The pictured computer simulation [7]  is based on
infrared data [8] from ESO [9] 's Very Large Telescope [10]  in Chile [11]
and X-ray [12]  data from NASA [13] 's orbiting Chandra X-ray Observatory [14]
. As the video starts, you quickly approach [15] Sgr A* [16] , the
supermassive black hole [17]  in the Galactic center [18] . Then looking out,
this 500-year time-lapse simulation [19] shows glowing gas and many points of
light orbiting all around you. Many of these points are young Wolf-Rayet star
[20] s that have visible hot winds blowing out into surrounding nebulas.
Clouds approaching close become elongated, while objects approaching too close
[21]  fall in. Toward the video's end the simulation repeats [22] , but this
time with the dynamic region surrounding Sgr A* [23]  expelling hot gas that
pushes back [24]  against approaching material.
