Event Horizon Telescope
Hello and welcome back, Earthlings!
I’m sure you have all been aware of the media BOOM regarding the first image of a black hole! I definitely recommend looking at all the awesome news articles about this incredible feat!
But this week, I want this blog post to look into what the Event Horizon Telescope actually is!
So here’s the Top 5 Facts about the Event Horizon Telescope!
1-The Telescope is actually not a SINGLE telescope, but rather an array around the world to form the Very Long Baseline Interferometry (VLBI)
2- The array was designed to not only image black holes, but to understand accretion disks formed around powerful massive blackholes and plasma jets shooting out of very active black hole centers
3-The idea for this entire project came about in 1993!
4-From ALMA: A schematic diagram of the VLBI mechanism of EHT. Each antenna, spread out over vast distances, has an extremely precise atomic clock. Analogue signals collected by the antenna are converted to digital signals and stored on hard drives together with the time signals provided by the atomic clock. The hard drives are then shipped to a central location to be synchronized. An astronomical observation image is obtained by processing the data gathered from multiple locations.
5-More telescopes are candidates (or locations) are in the running for inclusion in the array!
Thank you for reading and join us next week for an Earth Day Celebration surprise!
