Event Horizon Telescope (EHT) ialah teleskop tatasusun yang besar yang terdiri daripada rangkaian global teleskop radio. Projek EHT menggabungkan data dari beberapa stesen interferometri garis pangkal amat panjang (VLBI) di sekeliling Bumi dengan resolusi sudut yang mencukupi untuk memerhatikan objek saiz ufuk peristiwa lohong hitam supermasif. Sasaran pemerhatian projek termasuk dua lohong hitam dengan diameter diameter sudut yang paling besar seperti yang diamati dari Bumi: lohong hitam di pusat galaksi elips super-raksasa seperti Messier 87, dan Sagittarius A*, di pusat Bima Sakti.^[1]^[2]

Idea ini mula-mula dibayangkan oleh ahli astronomi radio Jerman Heino Falcke pada tahun 1993,^[3] dan aspek utama projek teori telah dibangunkan di projek Black Hole Cam yang dibiayai oleh EU, yang dipimpin oleh Falcke, Michael Kramer, dan Luciano Rezzolla.^[4]^[5]

Imej pertama lohong hitam, di pusat galaksi Messier 87, diterbitkan oleh Kerjasama EHT pada 10 April 2019.^[8] Tatasusun ini membuatkan pemerhatian ini pada panjang gelombang 1.3 mm dan dengan teori resolusi had belau hanya 25 mikro arka-saat. Rancangan masa depan melibatkan peningkatan resolusi tatasusun dengan menambah teleskop baru dan dengan mengambil pemerhatian panjang gelombang yang lebih pendek.^[1]^[9]
