To study how these stars' signals are distorted in space, the team turned to archival data from Arecibo, a 1,000-foot (305-meter) wide suspended radio dish that collapsed on Dec. 1, 2020 ...

This “parabolizing,” though an engineering marvel, can be done with only part of the dish, giving it an effective aperture of about 300 meters—the same as Arecibo. And FAST shares a weakness ...

the team had just made contact with the probe using the giant dish in Arecibo, sent a few commands, and started gathering data to plot where the spacecraft is and where it will be. A lot has ...

While this allows such searches to be conducted on quite large instruments (for example, the 305 m Arecibo dish, in Puerto Rico), the amount of telescope time available for the search is necessarily ...
