https://www.eso.org/public/images/eso1835a/ESO's exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way. New observations show clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside a four million solar mass black hole — the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole.

This visualisation uses data from simulations of orbital motions of gas swirling around at about 30% of the speed of light on a circular orbit around the black hole.

1. What is the significance of the "Picture of the Day: Gas Swirling Around a Black Hole"?

The "Picture of the Day: Gas Swirling Around a Black Hole" is a visual representation of the powerful forces at work near a black hole. It showcases how gas and other materials are pulled into the black hole and create a swirling disk around it.

2. How was this picture taken?

This picture was created using data from the Event Horizon Telescope (EHT), a network of radio telescopes around the world. The EHT uses a technique called Very Long Baseline Interferometry (VLBI) to combine the signals from multiple telescopes and create high-resolution images of objects in space.

3. What is the purpose of studying black holes?

Studying black holes allows scientists to better understand the laws of physics and how the universe works. Black holes also play a crucial role in the evolution of galaxies and have a significant impact on the surrounding environment.

4. How do black holes form?

Black holes form when a massive star runs out of fuel and collapses under its own gravity. The intense gravitational pull becomes so strong that even light cannot escape, creating a black hole.

5. Is it possible for anything to escape from a black hole?

Once something crosses the event horizon of a black hole, it is impossible for it to escape. However, there are some theories that suggest tiny particles, such as Hawking radiation, can escape from a black hole over time.
