Pronunciation: [ˈe͡ɪt] (IPA) 
The spelling of the word "EHT" may seem unusual, but it can be explained using the International Phonetic Alphabet (IPA). The word is pronounced as /ɛt/ with a short "e" sound and a soft "t" at the end. The spelling "EHT" uses a reversed order of the letters, which is a popular way of creating new words nowadays. While nonstandard spellings can sometimes be confusing, they can also add creativity and uniqueness to language.
EHT, short for Event Horizon Telescope, is an international collaborative project aimed at creating a virtual observatory with the objective of capturing images of black holes.
In its expanded form, EHT refers to an array of synchronized radio telescopes spread across multiple locations around the globe that work together to obtain extremely high-resolution images of distant celestial bodies. These telescopes employ a technique known as very-long-baseline interferometry (VLBI), which combines the data from different telescopes to create a virtual telescope with an effective diameter equal to the Earth's distance between them.
The main goal of EHT is to capture detailed images of the event horizon of black holes, which is the boundary beyond which nothing, not even light, can escape their immense gravitational pull. By capturing data from multiple telescopes simultaneously, EHT is able to achieve an unprecedented level of resolution, allowing scientists to study the dynamics and behavior of black holes in unprecedented detail.
EHT has successfully captured and released images of the black hole in the center of the galaxy Messier 87 (M87) in 2019 and the black hole at the center of the Milky Way galaxy (Sagittarius A*) in 2020. These accomplishments have opened up new avenues for study and understanding of black holes, gravitational physics, and the nature of the universe. EHT continues to push the boundaries of observational astronomy and revolutionize our knowledge of these enigmatic cosmic entities.
