ALMA is the largest and most powerful radio telescope operating at millimeter wavelengths (3.6 to 0.32 mm). It is also the most expensive ground-based telescope ever built ($1.5 B!). It is located in the Atacama Desert in Chile and is comprised of fifty-four 12 m dishes and twelve 7 m dishes. These radio dishes are movable and can be arranged with a maximum baseline of 16 km. When combining data from all 66 dishes, its resolution is (up to) 5x better than Hubble's. (Edit: I got the # of dishes wrong but I fixed it)

Huge fan of ALMA she is so awesome so cool the telescope ever. Her jewelry is based on Chilean Mapuche silverwork (trarilonco and trapelacucha). They look similar to the array of radio dishes to me. She doesn't wear all that casually though, maybe just the hair ribbons. Also she is best friends with JWST, they work together on many long-wavelength things! Like this!

These galaxies are in the process of merging and will eventually form the core of a massive galaxy cluster.

The 28 telescopes of the VLA are moved on parallel railroad tracks and can be arranged in several Y-shaped configurations with the help of a lifting locomotive. Currently the complex is in configuration B, which spreads out the telescopes over 7 miles. The maximum separation possible is 22.6 miles.

The further apart the telescopes are spaced, the larger the array’s eye, and the more detail it can see.
