The famous Arecibo Observatory in Puerto Rico completely collapsed in 2020. Now, scientists going through its final observations offer a major new asteroid report...
Using data collected by Arecibo between December 2017 and December 2019, scientists have released the largest radar-based report on near-Earth asteroids ever published. The report, published Sept. 22 in The Planetary Science Journal, includes detailed observations of 191 near-Earth asteroids, including nearly 70 that are deemed "potentially hazardous" — that is, large asteroids with orbits that bring them within 4.65 million miles (7.5 million kilometers) of Earth, or roughly 20 times the average distance between Earth and the moon.
Fortunately, none of these newly described asteroids pose an immediate threat to Earth; according to NASA, our planet is safe from deadly asteroid impacts for at least the next 100 years. However, scientists still pay close attention to near-Earth objects like these in case their trajectories happen to shift by some fluke of nature — say, a bump from another asteroid — thereby putting them on a collision course with Earth.
The new report also flagged several asteroids deemed worthy of future study, including an oddball space object called 2017 YE5 — an ultra-rare "equal mass" binary asteroid, made of two nearly identical size rocks that are constantly orbiting one another. (Each of the rocks is estimated to measure between 2,600 and 2,950 feet, or 800 to 900 meters, in diameter). The asteroid's high radar reflectivity may indicate an abundance of water ice beneath its surface, possibly making it a never-before-seen class of icy, equal mass, near-Earth asteroid, the researchers wrote.

I hold Pierce Brosnan responsible for that damage...
... but ... but the James Bond movie showed it destroyed way before 2020 ...
I wonder if they found Sean Bean’s remains.
(Mulder and Sculley went there, that's practically diagnostic of imminent destruction)Is such a thing even possible? Yes, it is.
according to NASA, our planet is safe from deadly asteroid impacts for at least the next 100 years.
Well, I know I will sleep better tonight...
I am INVINCIBLE!
:^D
“Collapsed Arecibo telescope”
Not too smart to put telescopes in the Third World.
I ended up getting kinda lost, but figured if I kept heading west it would be all ok eventually. I ended up at the Dominion Radio Observatory which is in the very middle of nowhere

I parked in the parking lot 1/4 mile away cause they did not need the car electronics messing up the alien signal reception and walked to check it out.
The Scientists were very cool and let me in and watch them reposition the dish and do some measurements.
Sad. Are they going to ever rebuild it, or build something similar somewhere?
Is such a hairstyle even possible? Yes, it is!
I understand that the site will become a STEM learning center.
Perhaps one is Wormwood???
We safe for the next 100 years unless Gates decides to interfere.
One of it’s support cables broke in Aug. 2020 and wasn’t fixed. Imagine that in Puerto Rico. In Nov., surprise!, another cable broke causing the collapse and complete destruction. Oh, well, no worries, tax dollars might one day build another.
Why?
The Greenbank radiotelescope was replaced after it failed unexpectedly. I don’t think there is any plan to rebuild Arecibo. As nice as it was, probably makes more sense to build a big ‘un nearer to the Equator.
Nice!
