Scientists described the collapse of the giant radio telescope in Puerto Rico this week as a "huge loss" after more than half a century of scientific discoveries in which it played a key role.
The US National Science Foundation had already said it would close the radio telescope after an auxiliary cable snapped in August, causing a 30-metre gash on the 305m-wide dish and damaging the receiver platform that hung above it, followed by a a main cable breaking in early November.
On Tuesday, the telescope's 900-tonne receiver platform and the Gregorian dome — a structure as tall as a four-story building that houses secondary reflectors — fell onto the northern portion of the vast reflector dish more than 100 metres below.
“It sounded like a rumble. I knew exactly what it was,” said Jonathan Friedman, who worked for 26 years as a senior research associate at the observatory and still lives near it.
“I was screaming. Personally, I was out of control," Mr Friedman told the Associated Press. "I don't have words to express it. It's a very deep, terrible feeling.”
Mr Friedman ran up a small hill near his home and confirmed his suspicions: a cloud of dust hung in the air where the structure once stood, demolishing hopes held by some scientists that the telescope could somehow be repaired.
The collapse was not a surprise because many of the wires in the thick cables holding the structure snapped over the weekend, Angel Vazquez, the telescope’s director of operations, said.
“It was a snowball effect,” he said. “There was no way to stop it. It was too much for the old girl to take.”
He said that it was extremely difficult to say whether anything could have been done to prevent the damage that occurred after the first cable snapped in August.
“The maintenance was kept up as best as we could,” he said. The National Science Foundation "did the best that they could with what they have”.
However, observatory director Francisco Cordova, said that while the NSF decided it was too risky to repair the damaged cables before Tuesday's collapse, he believes there had been options, such as relieving tension in certain cables or using helicopters to help redistribute weight.
Meanwhile, installing a new telescope would cost up to $350 million, money the NSF does not have, Mr Vazquez said, adding it would have to come from U.S. Congress.
“It's a huge loss,” said Carmen Pantoja, an astronomer and professor at the University of Puerto Rico who used the telescope for her doctorate. “It was a chapter of my life.”
Scientists worldwide had been petitioning US officials and others to reverse the NSF's decision to close the observatory. The NSF said at the time that it intended to eventually reopen the visitor centre and restore operations at the observatory’s remaining assets, including its two Lidar facilities used for upper atmospheric and ionospheric research, including analysing cloud cover and precipitation data. The Lidar facilities are still operational, along with a 12-metre telescope and a photometer used to study photons in the atmosphere, Mr Vazquez said.
“We are saddened by this situation but thankful that no one was hurt,” NSF Director Sethuraman Panchanathan said in a statement. “When engineers advised NSF that the structure was unstable and presented a danger to work teams and Arecibo staff, we took their warnings seriously.”
The telescope was built in the 1960s with money from the Defence Department amid a push to develop anti-ballistic missile defences. It had endured hurricanes, tropical humidity and a recent string of earthquakes in its 57 years of operation.
The telescope has been used to track asteroids on a path to Earth, conduct research that led to a Nobel Prize and determine if a planet is potentially habitable. It also served as a training ground for graduate students and drew about 90,000 visitors a year.
“I am one of those students who visited it when young and got inspired,” said Abel Mendez, a physics and astrobiology professor at the University of Puerto Rico at Arecibo who has used the telescope for research. “The world without the observatory loses, but Puerto Rico loses even more.”
He last used the telescope on August 6, just days before a socket holding the auxiliary cable that snapped failed in what experts believe could be a manufacturing error. The NSF, which owns the observatory that is managed by the University of Central Florida, said crews who evaluated the structure after the first incident determined that the remaining cables could handle the additional weight.
But on November 6, another cable broke.
Scientists had used the telescope to study pulsars to detect gravitational waves as well as search for neutral hydrogen, which can reveal how certain cosmic structures are formed. About 250 scientists worldwide had been using the observatory when it closed in August, including Mr Mendez, who was studying stars to detect habitable planets.
“I'm trying to recover,” he said. “I am still very much affected.”
What is a calorie?
A food calorie, or kilocalorie, is a measure of nutritional energy generated from what is consumed.
One calorie, is the amount of heat needed to raise the temperature of 1 kilogram of water by 1°C.
A kilocalorie represents a 1,000 true calories of energy.
Energy density figures are often quoted as calories per serving, with one gram of fat in food containing nine calories, and a gram of protein or carbohydrate providing about four.
Alcohol contains about seven calories a gram.

Islamophobia definition
A widely accepted definition was made by the All Party Parliamentary Group on British Muslims in 2019: “Islamophobia is rooted in racism and is a type of racism that targets expressions of Muslimness or perceived Muslimness.” It further defines it as “inciting hatred or violence against Muslims”.
What vitamins do we know are beneficial for living in the UAE
Vitamin D: Highly relevant in the UAE due to limited sun exposure; supports bone health, immunity and mood.
Vitamin B12: Important for nerve health and energy production, especially for vegetarians, vegans and individuals with absorption issues.
Iron: Useful only when deficiency or anaemia is confirmed; helps reduce fatigue and support immunity.
Omega-3 (EPA/DHA): Supports heart health and reduces inflammation, especially for those who consume little fish.

Safety 'top priority' for rival hyperloop company
The chief operating officer of Hyperloop Transportation Technologies, Andres de Leon, said his company's hyperloop technology is “ready” and safe.
He said the company prioritised safety throughout its development and, last year, Munich Re, one of the world's largest reinsurance companies, announced it was ready to insure their technology.
“Our levitation, propulsion, and vacuum technology have all been developed [...] over several decades and have been deployed and tested at full scale,” he said in a statement to The National.
“Only once the system has been certified and approved will it move people,” he said.
HyperloopTT has begun designing and engineering processes for its Abu Dhabi projects and hopes to break ground soon.
With no delivery date yet announced, Mr de Leon said timelines had to be considered carefully, as government approval, permits, and regulations could create necessary delays.
