This breakthrough was announced in a series of six papers published in a special issue of The Astrophysical Journal Letters.
The image reveals the black hole at the center of Messier 87, 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.
The EHT links telescopes around the globe to form an Earth-sized virtual telescope with unprecedented sensitivity and resolution.
The EHT is the result of years of international collaboration and offers scientists a new way to study the most extreme objects in the Universe predicted by Einstein’s general relativity during the centennial year of the historic experiment that first confirmed the theory.
This is an extraordinary scientific feat accomplished by a team of more than 200 researchers.
NSF has directly funded more than $28 million in EHT research, the largest commitment of resources for the project.
The telescopes contributing to this result wereALMA,APEX, theIRAM 30-meter telescope, theJames Clerk Maxwell Telescope, theLarge Millimeter Telescope Alfonso Serrano, theSubmillimeter Array, theSubmillimeter Telescope, and theSouth Pole Telescope. Petabytes of raw data from the telescopes were combined by highly specialized supercomputers hosted by theMax Planck Institute for Radio AstronomyandMIT Haystack Observatory.
