One of the major questions for the scientific community<\/strong> Globally, space-related issues were revealed. Yes, astronomers<\/a>, Astrophysicists and even amateurs wondered what they were really like. We're talking about a Black Hole<\/strong> And first of all, the images that had been seen were simulations based on theoretical models, following the physical laws we know.<\/p>\r\n

Now then, the Black holes are celestial bodies with a large mass in a very small volume<\/strong>. Because its internal mass is very dense and high, it generates such a strong gravitational field that not even light or matter can escape from it.<\/p>\r\n

An example of this is if our planet had the volume of a marble but the same weight. In other words, it would be a very small and extremely heavy object.<\/p>\r\n

A historic event<\/h2>\r\n

On April 10, 2019, at 3:00 p.m., the European Commission<\/strong>, he European Research Council<\/strong> and the International Event Horizon Telescope Project<\/strong> (EHT, for its initials in English) presented an unprecedented result in the observation of these space monsters.<\/p>\r\n

This being the first time an image of a black hole has been displayed, located about 55 million light-years away<\/strong>. In a massive galaxy<\/strong>, call from Messier 87 (M87)<\/strong>, in the Virgo cluster. Where the central dark area is the shadow of this giant.<\/p>\r\n

The photographed black hole He was baptized as Powehi<\/strong>. The name was given by Larry Kimura<\/strong>, a professor of Hawaiian language at the University of Hawaii at Hilo. The meaning<\/strong> It refers to a Hawaiian phrase that means \u201cdark fountain, embellished with endless creation.\u201d.<\/strong><\/p>\r\n

How did they get the image, the black hole?<\/strong><\/h2>\r\n

To capture the image, hundreds of scientists made a monumental effort. It's like photographing an object the size of an orange on the Moon from Earth, and with a resolution good enough to even recognize the target.<\/p>\r\n

So, for 5 days in April 2017<\/strong>, specialized astronomers They were observing with powerful radio telescopes around the world<\/strong>. In this way they functioned as one and had the power of a telescope the size of our planet Earth.<\/p>\r\n

The radio telescopes involved in the enormous research are the following:<\/p>\r\n
