Visit the Milky Way's supermassive black hole with 'Galactic Center VR' visualization (video)

A new virtual reality experience lets you fly closely, but safely, towards the supermassive black hole embedded in the heart of our galaxy, the Milky Way.

The "adventure" visualization is called Galactic Center VR and is based on data from NASA's Chandra X-Ray Observatory, as well as other telescopes. The latest iteration allows viewers to see 500 years of evolution at Sagittarius A* (Sgr A*), the black hole in the Milky Way's Center. You can view the experience for free from Steam or Vivepoint.

The Sgr A* simulation is based on modeling from 25 extremely bright and massive objects, called Wolf-Rayet stars. Similarly to supernovas, or star explosions, Wolf-Rayet stars push their outer layers of material into space. At Sgr A*, this star-shedding activity produces supersonic winds, and the material is picked up in the black hole's gravity.

"When the winds from the Wolf-Rayet stars collide, the material is heated to millions of degrees by shocks — similar to sonic booms — and produce copious amounts of X-rays," NASA said in a statement. "The center of the galaxy is too distant for Chandra to detect individual examples of these collisions, but the overall X-ray glow of this hot gas is detectable with Chandra's sharp X-ray vision."

The visualization displays about three light-years of space centered on Sgr A*, but the black hole is not shown to scale. It is enlarged by about 10,000 times to make it more visible; otherwise, NASA said, Sgr A* would only occupy a single pixel of space in the simulation.

Users can move around the simulation in different directions, playing with aspects such as the playback speed and the number of Wolf-Rayet winds shown. The visualization shows the Wolf-Rayet stars in white, with their orbits represented in gray. X-ray emissions are shown in blue and cyan, and wind material is portrayed in red and yellow. The overlap of wind materials and X-ray emissions is shown in purple.

Chandra is one of the two remaining NASA "Great Observatories" that launched to space in the 1990s and 2000s to observe astronomical phenomena in different wavelengths of light. The other observatories are the Hubble Space Telescope (still active), the Compton Gamma Ray Observatory (decommissioned in 2000) and the Spitzer Space Telescope (retired earlier this year).

Elizabeth Howell (she/her), Ph.D., is a staff writer in the spaceflight channel since 2022 covering diversity, education and gaming as well. She was contributing writer for for 10 years before joining full-time. Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, flying parabolic, working inside a spacesuit, and participating in a simulated Mars mission. Her latest book, "Why Am I Taller?", is co-written with astronaut Dave Williams. Elizabeth holds a Ph.D. and M.Sc. in Space Studies from the University of North Dakota, a Bachelor of Journalism from Canada's Carleton University and a Bachelor of History from Canada's Athabasca University.

    Hi, we are working on getting other VR headsets supported as well. For parties interested in creating their own bindings for the Index, Rift, or WMR, please see our post on our Steam communities discussion board:
