Good article.

But the most ambitious project focused on the galactic center is the Event Horizon Telescope, an enormous interferometer made from a dozen observatories stretching from Hawaii to the South Pole. The goal, when it comes online this spring, is to capture an image of Sgr A* with enough resolution to see the event horizon itself.

If they verify the event horizon, it's definitely a black hole.

Will look forward to observations from the Event Horizon Telescope!
