The Conversation "Astronomers to peer into a black hole for first time with new Event Horizon Telescope"

March 17, 2017

"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 actually been “seen”. But this could now be about to change as an international team of astronomers is connecting a number of telescopes on Earth in the hope of making the first ever image of a black hole."

The Guardian: "Edge of darkness: looking into the black hole at the heart of the Milky Way"

February 26, 2017

"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 photograph of this interstellar behemoth – an extraordinarily ambitious feat that will involve the creation of a radio telescope that has the effective size of our entire planet and whose operation will involve scientists from four continents."

BBC News: "Event Horizon Telescope ready to image black hole"

February 16, 2017

"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.

There is optimism that observations to be conducted during 5-14 April could finally deliver the long-sought prize."

"Event Horizon Telescope...

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."
