Thought of the day by Socrates

To fear death, my friends, is only to think ourselves wise, without being wise: for it is to think that we know what we do not know.

Observation Log for NGC 4036

Supermassive black hole M-87

I still cannot realize that the human being has been able to take the first picture of the event horizon of a black hole.

What I have been able to observe is that the media in different languages ​​refer to this photo as the photo of the black hole when in reality it is the event horizon, these are very different parts.

This image is the achievement of a great human and technical effort that spans the 5 continents. I am going to explain it to you.

First, all the news will have this acronym somewhere EHT, which is Event Horizon Telescope (known by its acronym in English, Event Horizon Telescope) The set of millimetre telescopes that currently form this network are: Alfonso Serrano Large Millimeter Telescope (GTM) from Mexico, Atacama Large Millimeter Array (ALMA) from Chile, South Pole Telescope (SPT) at the South Pole, Atacama Pathfinder Experiment (APEX) in Chile, James Clerk Maxwell Telescope (JCMT) in Hawaii, Submillimeter Array (SMA ) in Hawaii, the Submillimeter Telescope (SMT) in Arizona and the 30-m Millimeter Radio Astronomical Institute (IRAM) in Spain.

After this exploit, we can only wait for the next great photo or maybe a video that would be interesting.
