You'll definitely have to! We have some new things since then including a recently updated Visitor Center & Gift Shop, not to mention the cool #ngVLA prototype antenna sitting out back 👀

Awesome photos! Have you been out to the VLA again since that 1998 pilgrimage? 📡

The antennas will be able to all operate together as a single array, or be divided into subarrays to optimize the use of observing time for specific use cases.

244 of the proposed dishes will be 18m in diameter, like the prototype antenna pictured above, while an additional 19 6m dishes will make up a short-spacing array at the heart of the telescope.
