Default $19 million might produce the first ever image of a black hole

So much has been in the Science news lately. Yet I gave on even posting more than the link as it is most all copyrighted and I can't afford the cost that comes with breaking this law.

Yet I can take some of this news, d a seach and find a site which isn't copy righted, so far it has been "The Verge"

$19 million might produce the first ever image of a black hole

Now each of you must have seen either in the news/on line or some TV Show on Science saying the Milky Way has at its center a black hole and we believe every other galaxy must have one to. Yet by reading this article one can see it was a damn lie, till possibly now if we spend 19 million mre on these lying braina a**es.

Astrophysicists think there's a supermassive black hole at the center of the Milky Way galaxy. It's supposed to be four million times more massive than our Sun, but despite its stupendous size, we've never been able to see it. That might soon change. The European Research Council has given 14 million euros ($19.3 million) to the creators of BlackHoleCam, a project that will use radio telescopes and supercomputers to try to prove the existence of what Luciano Rezzolla, a principal investigator for BlackHoleCam, calls "one of the most cherished astrophysical objects."

BlackHoleCam's name is slightly misleading. It won't be able to image the black hole itself, instead using the event horizon that it expects to see to confirm the hole's existence. The event horizon — a phenomenon predicted by Einstein — is the boundary of spacetime beyond which the pull of gravity is so great that escape is impossible. Space.com reports the Milky Way's black hole should betray its event horizon by casting "a dark shadow" over bright radio wave emissions given off as gas is pulled into the black hole.

BlackHoleCam will try to image the black hole's event horizon to confirm its existence

The project will use an approach called Very Long Baseline Interferometry, in which multiple observatories — including Chile's new ALMA telescope — are focused on one object, pulling in data that's then fed through a supercomputer. BlackHoleCam will also work closely with the Event Horizon Telescope, an American-led group who also use VLBI in their efforts. As befitting an object so large our entire galaxy spins around it, we have to use something the size of a planet to see it: Space.com says by using Very Long Baseline Interferometry, BlackHoleCam turns the Earth itself into a vast virtual telescope.

Heck last night I heard they have a new camera that will watch just one spot in the night sky which would cover 2 million stars. Why I missed that part as I had set my TV Guide to another show and it came jump to the new one and I tried to go back but I had missed it.

Astronomers close in on first direct view of a black hole
Tuesday, Apr. 04, 2017 - If Avery Broderick’s wishes come true, the next 10 days will bring something new to humanity’s view of the universe. For the first time, the University of Waterloo physicist says, there could be “visceral, direct evidence that there are monsters in the night.”
Quote:
The monsters Dr. Broderick has in mind are supermassive black holes: terrifying giants that lurk in the hearts of galaxies, including our own, where they can devour stars and interstellar gas like cosmic vacuum cleaners. Fortunately, Earth is in no danger of encountering such a lethal entity. The nearest one is at least 25,000 light years away from our solar system’s quiet celestial suburb. But astronomers have long known that something very dark and heavy is sitting at the galactic centre. Indirect evidence points to a black hole that is more than 30 times the sun’s diameter and a staggering 4.3 million times the sun’s mass. The extreme gravity of such a dense object would be enough to trap light as well as matter. Falling into it would be a one-way trip, even for a laser beam. (Hence the term “black hole.”)

Now, a team of scientists, including Dr. Broderick, is hoping to catch a glimpse of the black hole at the centre of the Milky Way. Their aim is essentially to take a picture of its dark circular rim – the point of no return that physicists call the event horizon – in silhouette against the glowing gas that swirls around it. If the effort succeeds, it could provide a crucial test of Einstein’s general theory of relativity as well as offer a direct look at one of the most extreme environments in nature. “We have every expectation that we are just going to get fantastic data,” said Dr. Broderick, whose work on the project is supported by the Perimeter Institute for Theoretical Physics.

The team members’ confidence stems from the increasingly powerful tool they are using to peer at the galaxy’s dark and elusive heart. Dubbed the Event Horizon Telescope, it is actually a network of radio dishes spread across the globe. Together they exemplify the adage that the sum is greater than the parts. Radio waves offer the only way to observe the environment around the Milky Way’s giant black hole because, unlike visible light, they are not blocked by the obscuring clouds of interstellar dust between Earth and the galactic centre. Even a fairly crude antenna can pick up the static coming from centre of the Milky Way – an observation that was first made in the 1930s.

But turning the galaxy’s radio noise into a high-resolution image requires a different technique. If properly calibrated, several widely separated dish antennas can act like a single giant antenna with a much sharper view. In the case of the Event Horizon Telescope, which makes use of antennas in Hawaii, Arizona, Mexico, Spain and Chile and at the South Pole, the project’s virtual “dish” is nearly as big as Earth. The group, led by Harvard University researcher Shep Doeleman, has been working on the project for more than a decade and observing the radio energy emitted by the galactic centre with ever-improving clarity. But on Wednesday, for the first time, they are adding the world’s most sensitive radio observatory to their network – the 66-dish Atacama Large Millimeter/Submillimeter Array (ALMA) located on a high plateau in the Chilean Andes.

Construction Begins in Atacama Desert on World's Largest Telescope...

Construction Begins in Chilean Desert on World's Largest Telescope
May 26, 2017 — Construction began in Chile on Friday on the European Extremely Large Telescope, which when completed will be the world's largest optical telescope, some five times larger than the top observing instruments in use today.
Quote:
The size of the ELT has the potential to transform our understanding of the universe, say its backers, with its main mirror that will measure some 39 meters (43 yards) across. Located on a 3,000 meter-high mountain (9,800 feet) in the middle of the Atacama desert, it is due to begin operating in 2024.

Spark the spotting of more planets

Among other capabilities, it will add to and refine astronomers' burgeoning discoveries of planets orbiting other stars, with the ability to find more smaller planets, image larger ones, and possibly characterize their atmospheres, a key step in understanding if life is present. “What is being raised here is more than a telescope. Here we see one of the greatest examples of the possibilities of science,” said Chilean President Michelle Bachelet in a speech to mark the beginning of construction at the site.

Dry air makes for near perfect conditions

The dry atmosphere of the Atacama provides as near perfect observing conditions as it is possible to find on Earth, with some 70 percent of the world's astronomical infrastructure slated to be located in the region by the 2020s. The ELT is being funded by the European Southern Observatory, an organization consisting of European and southern hemisphere nations. Construction costs were not available but the ESO has said previously that the ELT would cost around 1 billion euros ($1.12 billion) at 2012 prices.
