The Largest Telescope in Human History

The largest telescope in human history is being built in the Chilean desert. Construction has been underway since 2014, and it is planned to be put into operation in 2028, and the project costs could exceed $1.5 billion

Its main mirror will be about 4 times larger than any existing telescope, which will allow it to capture 15 times more light and surpass the orbital Hubble in detail by 16 times
