Puerto Rico's iconic Arecibo Observatory has sustained some significant damage from Hurricane Maria, officials reported today (Sept. 22).
The storm hit the island as a Category 4 hurricane Wednesday (Sept. 20) and left widespread destruction in its wake. Without power, phones or internet service, the Arecibo Observatory has been offline since the storm hit.
The Arecibo Observatory houses the world's second-largest radio telescope. While the overall structure of the telescope is still standing, it sustained some pretty serious damage from Hurricane Maria, according to an update from the Universities Space Research Organization (USRA), which helps to operate the Arecibo Observatory.
One telescope operator at Arecibo managed to contact USRA officials Thursday (Sept. 21) via a short-wave radio transmission. National Geographic's Nadia Drake reports that Pennsylvania State University professor Jim Breakall spoke with the telescope operator, who was identified as Ángel Vazquez, and said staff members and their families were safe after sheltering at the facility. Vazquez also detailed some of the damage done to the iconic telescope.
A 96-foot (29 meters) antenna that was suspended above the telescope's 1,000-foot (305 m) dish was lost as a result of the hurricane, "with falling debris puncturing the dish in several places," USRA officials said in the update. The antenna was affixed to a platform suspended about 500 feet (150 meters) above the dish, which is made out of a metal mesh. [The Arecibo Observatory: Puerto Rico's Giant Radio Telescope in Photos]
"Also, a separate 12-meter [40-foot] dish used as a phase reference for Very Long Baseline Interferometry (VLBI) was lost," the USRA update states. VLBI is a method astronomers use to make radio telescopes more powerful by creating a network of smaller telescopes that work together.
Officials have yet to conduct "a full assessment of the damage, repairs that are needed and when the observatory can resume observations," Nicholas White, senior vice president for science at the USRA, said in a statement.
Getting to the observatory will be a challenge, though, as roads are covered in debris and are inaccessible at this time, USRA officials said.
Before the hurricane, Arecibo officials tweeted that the observatory would reopen to staff today, though it seems unlikely that anyone who didn't take shelter at the observatory will be able to report for work.
The visitor center is officially closed through Wednesday (Sept. 27), Arecibo representatives said on Twitter Monday (Sept. 18) as the observatory was preparing for the second major hurricane to hit Puerto Rico this month. Hurricane Irma also hit the island on Sept. 6, though the Arecibo Observatory made it through that storm relatively unscathed.
