A star 8,000 light years from Earth is on the verge of a huge supernova explosion, which could produce the Milky Way’s first gamma-ray explosion, a dangerous and extremely energetic event.

Australian scientists at the University of Sydney discovered the rare ‘God of chaos’ star, which they say could produce the Milky Way’s first known gamma-ray burst, a lethal combination of dust and gas mixed with wind as fast as 12 million km/ph, which is one of the most extreme energetic events after the Big Bang.

With the power to unleash as much energy in 10 seconds as the Sun does in its entire lifetime, gamma-ray bursts (GRBs) are the most energetic events in the universe, second only to the Big Bang itself. Given how sudden they are, we don’t usually get any warning, but now astronomers have spotted the telltale signs of a star system that could blow its lid any moment – and it’s far too close to Earth for comfort.

According to a recent paper, the Earth is caught directly in the crosshairs of a cosmic hurricane. A swarm of nearly 100 stars, accompanied by an even greater amount of dark matter, is aimed directly at our stellar neighborhood and there’s nothing we can do to stop it; in fact, the vanguard is already upon us. This sounds like a perfect summer blockbuster movie, starring The Rock and Chris Pratt, or maybe Scarlett Johansson and Charlize Theron.

Researchers have created a virtual reality simulation of a supermassive black hole. In a recent paper in “Computational Astrophysics and Cosmology” they present their latest visualization. The simulation is based on the black hole in the center of our own Galaxy; Sagittarius A* (Sgr A•. Read this SpringerOpen blog to learn more. https://bit.ly/2S2Xh8p

For the first ever time, scientists have created a virtual reality (VR) simulation of Sagittarius A*- the black hole at the center of our galaxy. The simulation allows helps viewers to better visualize the phenomenon and study the black holes as well.

With the aim of creating a VR simulation of Sagittarius A*, scientists at Radboud University, The Netherlands and Goethe University, Germany come together and used an astrophysical model of Sagittarius A*. Through this model, they were able to capture an image series that then put together to create a 360-degree virtual reality simulation of the black hole.

The simulation can be seen using VR consoles. The most fascinating thing about this simulation is, it created one of the most realistic views of the direct surroundings of the black hole. Moreover, it is expected to help scientists to study the behavior of the black hole.
