The Event Horizon Telescope (EHT) famously provided humankind with thefirst image of a black holein April 2019.
An image of a black hole is really an image of the black holes shadow.
In the collaborations recent studypublishedtoday inThe Astronomical Journalthe team describes the method by which they improved the telescopes resolution.

Instead, the collaboration observed shorter wavelengths of light, yielding sharper images.
When the collaboration refocuses its attention on black holes, the improvement of resolution could be significant.
