Puerto Rico's Arecibo Observatory is falling apart, leaving astronomers worried about their research

Last week, one of the telescope’s main steel cables that was capable of sustaining 544,000 kilograms snapped under only 283,000 kilograms.

"...


The giant, aging cables that support one of the world’s largest single-dish radio telescopes are slowly unravelling in this US territory, pushing an observatory renowned for its key role in astronomical discoveries to the brink of collapse.

The Arecibo Observatory, which is tethered above a sinkhole in Puerto Rico’s lush mountain region, boasts a 1,000-foot-wide (305-meter-wide) dish featured in the Jodie Foster film “Contact” and the James Bond movie “GoldenEye.” The dish and a dome suspended above it have been used to track asteroids headed toward Earth, conduct research that led to a Nobel Prize and helped scientists trying to determine if a planet is habitable

...so the "physics" go, a radar trlescope can detect anything its rays get reflected off. And if the distance is a light year away and the position is right, they will receive a reflexion of the object....

...the further away the object is the bigger ammount of light years do they have to wait for any reflection, and see if it coincides with the visual image of the location...!

So what resolution solving power does an array of radar telescopes laid out in 100's of meters in a flat area, to see our MOON closer to observe smaller details? ...

Ohh, sorry we have no interest for that, we are looking for other Planets many "light years away" and what a waiting time of years ...!

BY THE WAY ASTEROIDS ARE INSIDE THE SOLAR SYSTEM AND COMETS COME INTO THE SOLAR SYSTEM TO GO AROUND THE SUN IN THEIR AMAZING ORBITS OF MOSTLY FAST SPEED AND TAILS OF MELTING ICE...!
