Science fact: Astronomers reveal first image of a black hole
Posted by Michael Lance in categories: cosmology, science
WASHINGTON (AP) — Scientists on Wednesday revealed the first image ever made of a black hole, depicting a fiery ring of gravity-twisted light swirling around the edge of the abyss.
The picture, assembled from data gathered by eight radio telescopes around the world, shows the hot, shadowy lip of a supermassive black hole, one of the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades. It is along this edge that light bends around itself in a cosmic funhouse effect.
“We have seen what we thought was unseeable. We have seen and taken a picture of a black hole,” Sheperd Doeleman of Harvard, leader of a team of about 200 scientists from 20 countries, announced as the colorized orange-and-black picture was unveiled.

In April 2017, scientists used a global network of telescopes to see and capture the first-ever picture of a black hole, according to an announcement by researchers at the National Science Foundation Wednesday morning. They captured an image of the supermassive black hole and its shadow at the center of a galaxy known as M87.
This is the first direct visual evidence that black holes exist, the researchers said. In the image, a central dark region is encapsulated by a ring of light that looks brighter on one side.
The massive galaxy, called Messier 87 or M87, is near the Virgo galaxy cluster 55 million light-years from Earth. The supermassive black hole has a mass that is 6.5 billion times that of our sun.

On 10 April 2019 at 15:00 CEST (Brussels time) the European Commission will present a ground-breaking discovery by Event Horizon Telescope — an international scientific collaboration aiming to capture the first image of a black hole by creating a virtual Earth-sized telescope. EU-funded researchers play a key role in the project.
Six press conferences around the world will take place simultaneously In Europe, Commissioner Moedas and lead scientists funded by the European Research Council will hold a press conference in Brussels to unveil the discovery.

Astronomers Capture First Image of a Black Hole
Posted by Klaus Baldauf in categories: cosmology, innovation
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.
This breakthrough was announced today in a series of six papers published in a special issue of The Astrophysical Journal Letters. The image reveals the black hole at the centre of Messier 87 [1], a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun [2].
The EHT links telescopes around the globe to form an unprecedented Earth-sized virtual telescope [3]. The EHT offers scientists a new way to study the most extreme objects in the Universe predicted by Einstein’s general relativity during the centenary year of the historic experiment that first confirmed the theory [4].

LIGO has spotted another gravitational wave just after turning back on
Posted by Genevieve Klien in categories: cosmology, physics
One week after LIGO switched back on, it has already detected the gravitational waves from another pair of merging black holes, marking the beginning of a new era of gravitational wave astronomy.
