What makes the Event Horizon Telescope (EHT) so special? In this video, we explore how the EHT managed to capture the first-ever image of a black hole, located at the center of the M87 galaxy, 55 million light-years away. This supermassive black hole has a mass of 4 billion suns and is far larger than the one in our own galaxy. Learn about the technology behind this remarkable achievement and why it’s a groundbreaking moment in science!

Could this cosmic showdown reverse the flow of time? Pitting a black hole against a gamma-ray could spell some serious danger for our Universe. Extremely dense and with a lot of gravity, most black holes are the remnants of massive stars. Compressed to a point called a singularity. At this infinitely small point in the center, conceptions of space and time break down. Gamma-ray bursts are the strongest and brightest explosions in the Universe. In one second, gamma-ray bursts emit as much energy as the Sun will emit during its entire 10-billion year lifespan.

Image of the supermassive black hole Sagittarius A* (Sgr A*). from the Event Horizon Telescope (EHT) collaboration "has uncovered strong and organised magnetic fields spiralling from its edge," according to ESO. Credit: ESO
