We present the first event-horizon-scale images and spatiotemporal analysis of Sgr A* taken with the Event Horizon Telescope in 2017 April at a wavelength of 1.3 mm. Imaging of Sgr A* has been conducted through surveys over a wide range of imaging...
In this paper we quantify the temporal variability and image morphology of the horizon-scale emission from Sgr A*, as observed by the EHT in 2017 April at a wavelength of 1.3 mm. We find that the Sgr A* data exhibit variability that exceeds what can be...

"Scientists believe they are on the verge of obtaining the first ever picture of a black hole. They have built an Earth-sized "virtual telescope" by linking a large array of radio receivers - from the South Pole, to Hawaii, to the Americas and Europe...
"After completing five nights of observations, today astronomers may finally have captured the first-ever image of the famous gravitational sinkhole known as a black hole. [...] As the final observing run ended at 11:22 a.m. ET, team member Vincent Fish...
"This year, for the first time, the EHT will add dishes in Chile and Antarctica, sharpening its resolution and raising expectations. Astronomers now hope to see how the black holes whip the hot gas around them into accretion disks and spawn matter-spewing...
"Ever since first mentioned by Jon Michell in a letter to the Royal Society in 1783, black holes have captured the imagination of scientists, writers, filmmakers and other artists. Perhaps part of the allure is that these enigmatic objects have never...
"The Milky Way’s great black hole is 25,000 light years distant, surrounded by dense clusters of stars, shrouded by interstellar dust and, like all other black holes, incapable of emitting light. Yet scientists believe they will soon be able to take a...
"Around the world, observatories gaze at the sky. But what if you could combine these to make a single high-resolution image – and examine the event horizon of the supermassive black hole at the centre of the Milky Way galaxy while you're at it? This is...
"Soon ALMA will take on perhaps the most ambitious endeavor of its brief existence. Over 10 days in early April, it will join radio telescopes at five other sites spanning the globe, from Hawaii to the South Pole, in an attempt to capture the shadow of a...
"More than 26,000 light years away, deep within the heart of our galaxy, lies Sagittarius A* - four millions Suns' worth of unseen mass concentrated into an area just nine times the size. Sheperd Doeleman, assistant director of the MIT Haystack...
"A network of nine radio telescopes, dotted around the globe, is set to take the first ever picture of a black hole's event horizon in 2017. The project, called the Event Horizon Telescope, has completed most of its technical preparations as well as...
