It happened in less than 10 seconds, two years ago today: The Arecibo Observatory’s 1,000-foot radio dish collapsed, eliminating one of the world’s most renowned sources of radio observations.

That research involves radio wave data collected by Arecibo.

The National Science Foundation said that the site of the destroyed telescope would become an education center, set to open in 2023.

“On the other hand, the proposed facility strikes me as a pale substitute for what was lost at Arecibo, and it does little to plug the scientific hole that the loss of the big dish left behind.”.

The document didn’t detail any support funding for Arecibo’s other scientific operations, namely its lidar facility and its still-very-much-intact 36-foot radio telescope.

What becomes of Arecibo—even what this proposed education center will look like—remains unclear

Radio astronomy is worse off for the dish’s unfortunate end, though the decades of data collected there will live on as a scientific resource for years to come
