The Arecibo telescope collapsed in 2020 because its giant cables slipped out of its socket. This caused the cable to crash through the Earth-based observatory.
Because of this, operators had to shut down the giant telescope. But, before it died, the observatory was able to warn experts about near-Earth asteroids.
Its data was presented in the study titled "Arecibo Planetary Radar Observations of Near-Earth Asteroids: 2017 December-2019 December," which was published in the Planetary Science journal.
According to Science Alert's latest report, the data used in the study was generated by Arecibo Observatory between December 2017 and December 2019.
The giant telescope's data showed that there are over 190 near-Earth asteroids. The new study claims that some of them (around 70) are possibly dangerous.
