Black Hole Photos Could Get Even Clearer with Space-Based Telescopes

In space, the Event Horizon Imager (currently at concept stage) could have a resolution more than five times that of the Event Horizon Telescope on Earth, which took the first-ever picture of a black hole.

The first-ever photo of a black hole amazed people across the world. Now, astronomers are aiming to take even sharper pictures of these enigmatic structures by sending radio telescopes into space.

The historic photo became public on April 10, when the worldwide research collaboration known as Event Horizon Telescope (EHT) unveiled the hazy but nevertheless incredible photo of the supermassive black hole at the center of the galaxy Messier 87.

Astronomers at Radboud University in the Netherlands have recently shared their plans to work with the European Space Agency (ESA) and others to get a better look at black holes by placing two to three satellites in a circular orbit around Earth. The concept is called the Event Horizon Imager (EHI).
