Astronomer explains world’s sharpest images

Date:

In 2019, a fuzzy ring of light caused a sensation as the first image of a black hole. In the meantime, researchers have not only ‘sharpened’ using AI, but a collaboration of telescopes has also achieved the highest resolution ever seen from Earth. An astronomer explains to us what technology makes it possible, what the research milestone means, and just how ‘sharp’ images can still be.

That’s what you get with scientific ‘milestones’ or ‘quantum leaps’. They are used to describe great achievements, even if they are very small. The balancing act is far from just linguistic. When quantum or particle physicists want to unlock the secrets of the often ‘crazy’ world of the smallest units, they sometimes do so with enormous particle accelerators such as those at CERN in Geneva.

When we look into the depths of interstellar space, a bridge must also be built between the large and the small to achieve breakthroughs. The Event Horizon Telescope (EHT) Collaboration, an association of (radio) telescopes spread across the world, has now achieved this.
