Sagittarius A*: Take a virtual tour into supermassive black hole heavier than 4 million suns

India Today  

Scientists for the first time have created a virtual reality simulation of Sagittarius A* - the black hole at the centre of our galaxy - that allows viewers to better visualise the phenomenon. The authors suggest that this virtual reality simulation could be useful for studying black holes. "Our virtual reality simulation creates one of the most realistic views of the direct surroundings of the black hole and will help us to learn more about how black holes behave," said Jordy Davelaar, corresponding author of the study published in the journal Computational Astrophysics and Cosmology. There may be many stellar mass black holes in Milky Way, Earth's galaxy An artist's drawing shows the current view of the Milky Way galaxy. These black holes have masses that are more than one million suns together These black holes have Scientists have found proof that every large galaxy contains a supermassive black hole at its center The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A*.
