Meanwhile, facilities at Arecibo are still operational, besides (obviously) the observatory’s marquee telescope. As reported by PhysicsWorld, earlier this year the NSF announced that the collapsed telescope would be maintained (rather than closed) through September, to allow for a smooth transition into Arecibo’s next form—whatever that might be.
In a paper submitted to the preprint server arXiv last month, a team of astronomers, including Anish Roshi, the head of radio astronomy at Arecibo, proposed that a tiltable array of antennae could form the Next-Generation Arecibo Telescope (NGAT).
Instead of one massive dish (approximately 984 feet across, or 300 meters) the plan describes a cost-effective alternative between 426 feet and 574 feet across (130 meters to 175 meters). The weight of the proposed NGAT is 4,300 tons. The team argues that the proposed telescope’s performance “surpasses all other radar and single dish facilities.”

That’s a big claim, but one that may be needed to make the telescope a reality. When the NSF announced that an education center would replace Arecibo (rather than a new telescope), Sean Jones, the assistant director for directorate of mathematical and physical sciences at NSF, told the AP that the United States had alternative radar facilities that could cover the data footprint vacated by Arecibo.
Whatever takes the place of Arecibo certainly won’t be the same scale as the historic observatory, whose data is still being incorporated in new research. But its successor will somehow fit the goal of scientific pursuit, even if it’s not directly involved in scientific observations.
