This still image is a single image from a 360-degree ultra-high definition immersive visualization that allows users to visualize the center of our galaxy as if they were sitting at the position of the supermassive black hole of the Milky Way ( Sgr A *). ).
Do you want to take a trip to the center of the Milky Way? Discover a new ultra-high definition immersive visualization. This 360 film offers an unprecedented opportunity to look around the center of the galaxy, from the point of view of the central supermassive. black hole, in any direction chosen by the user.
By combining NASA's Ames supercomputer simulations with data from NASA's Chandra X-ray observatory, this visualization offers a new perspective of what is happening in and around the center of the Milky Way. It shows the effects of dozens of massive stellar giants with strong winds blowing from their surfaces in the region just a few light-years away from the supermassive black hole known as Sagittarius A * (Sgr A *).
A new immersive, high-definition, 360-degree visualization allows the viewer to see the center of our galaxy as if sitting in the position of the supermassive black hole of the Milky Way (Sgr A *). By combining supercomputer simulations with Chandra data, the visualization shows the effects of dozens of giant stellar giants with strong winds blowing over their surfaces in the region spanning a few light-years around Sgr A *. Blue and cyan represent hot gas X-ray emissions with temperatures of tens of millions of degrees, while red emission indicates ultra-violet emissions from more moderately dense gas regions with temperatures of tens of thousands of times. degrees, and yellow indicates the highest densities.
These winds provide a set of materials for the supermassive black hole to potentially feed. As in a previous visualization, the observer can observe dense masses of material flowing to Sgr A *. These clusters formed when massive star winds near Sgr A * clashed. In addition to watching the movement of these clumps, spectators can watch the relatively low density gas drop towards Sgr A *. In this new visualization, the blue and cyan colors represent the X-ray emissions of hot gas with temperatures of tens of millions of degrees; red represents regions of colder, moderately dense gas with temperatures of tens of thousands of degrees; and yellow shows the colder gas with the highest densities.
It is found that a collection of gas emitting X-rays moves slowly when it is away from Sgr A *, and then accelerates and whips the viewer as he returns. Sometimes clumps of gas collide with gases ejected by other stars, which causes an X-ray flash when the gas is heated and then cools rapidly. Further from the viewer, the film also shows fast stellar wind collisions producing X-rays. These collisions are thought to be Chandra's main source of hot gas.
When a gas explosion occurs very close to the black hole, the ejected gas collides with the material flowing away from the massive stars by the wind, pushing it back and causing it to shine in X-rays. Blast decreases, winds return to normal and X-rays fade.
The 360 degree video of the Galactic Center is ideally viewed with the help of virtual reality glasses, such as Samsung Gear VR or Google Cardboard. The video can also be viewed on a smartphone using the YouTube application. Moving the phone reveals a different portion of the film, mimicking the effect of virtual reality glasses. Finally, most browsers on a computer also allow you to view videos on YouTube 360 degrees. To look around, click and drag the video or click the directional pad in the corner.
Dr. Christopher Russell of the Pontifical Catholic University of Chile (Pontifical Catholic University) presented the new visualization at the 17th meeting of High Energy Astrophysics (HEAD) of the American Astronomical Society at Monterey, California. Huntsville, Alabama, runs the Chandra program for the NASA Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, controls Chandra's scientific and aerial activities.
