The $1.4 billion telescope, which is still being built on Mauna Kea, Hawaii's tallest mountain, is still under development

This large telescope, which can be seen in northern Chile's Atacama Desert, was created to provide insights into how stars are generated as well as precise imaging of how planets are formed.

I was astounded when I saw pictures of the big telescope's construction site. When it is finished, the European Extremely Large Telescope will be the biggest telescope ever.

2. Hubble Space Telescope – $2.5 Billion

The Hubble Space Telescope is ranked second on our ranking of the five most costly telescopes ever. Earth-based ground telescopes are significantly less expensive than those in orbit.
