Wired: "Distant black hole may disprove Einstein's theory of relativity"

December 24, 2016

"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 Observatory, believes this mysterious entity is a supermassive black hole - and he's building a telescope the size of the Earth to prove it."

Cosmos Magazine: "How an Earth-sized telescope will 'see' a supermassive black hole"

November 30, 2016

"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 the idea behind the Event Horizon Telescope, a virtual telescope so big it spans continents and hemispheres thanks to an imaging technique called interferometry."

BBC News: "Event horizon snapshot due in 2017"

January 8, 2016

"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 extensive theoretical calculations.

It will focus on Sagittarius A*, the black hole at the Milky Way's centre.

Speaking at an astronomy conference in Florida, EHT team member Feryal Ozel said all the elements were in place."

Science: "Globe-spanning telescope array glimpses magnetic field around Milky Way’s black hole"

December 3, 2015

"A wide-ranging array of radio dishes trained on the supermassive black hole at the center of our galaxy has revealed a glimpse of the magnetic field close to the Milky Way’s dark heart. The results could help explain why black holes, although not emitting any light themselves, are able to make the churning gas and dust around them shine with the brightness of thousands of stars."

April 21, 2015

"Astronomers building a globe-spanning virtual telescope capable of photographing the "event horizon" of the black hole at the center of our Milky Way have extended their instrument to incorporate the South Pole Telescope (SPT), a 280-ton radio telescope located at the National Science Foundation's (NSF) Amundsen-Scott South Pole Station in Antarctica"

PBS: How a global network of telescopes may give us first glimpse of a black hole

November 25, 2014

"Even though black holes are vital to our understanding of the universe, no one has ever seen one -- yet. To change this, a team of scientists in northern Chile, is using a network of telescopes around the globe to capture an image of a black hole for the first time to prove Einstein’s Theory of General Relativity. Rebecca Jacobson reports."
