The astronomers' idea is to photograph the circular opaque silhouette of a black hole cast on a bright background. The shadow's edge is the event horizon, a black hole's point of no return.

For the Event Horizon Telescope, the large collecting area of ALMA, combined with choosing a wavelength where supermassive black holes are very bright, ensured sufficient photons.

In a groundbreaking achievement, the Event Horizon Telescope (EHT) Collaboration has conducted the highest-resolution observations ever achieved from Earth, detecting light at 345 GHz from the ...

Almost exactly one year ago today, the Event Horizon Telescope collaboration released the first-ever image of a black hole's event horizon. Its publication marked the first time that we'd ever ...

The Event Horizon Telescope has released the first-ever image of a black hole. This image will provide unparalleled insight into these mysterious, exotic, and invisible objects.

After taking the first images of black holes, the Event Horizon Telescope (EHT) is poised to reveal how black holes launch powerful jets into space.

A nearby supermassive black hole is erupting, and astronomers spotted the outburst using the Event Horizon Telescope.

This planet-sized telescope just took a major step towards delivering the first video ever of a churning supermassive black hole.

After taking the first images of black holes, the ground-breaking Event Horizon Telescope (EHT) is poised to reveal how black holes launch powerful jets into space. Now, a research team led by ...
