Where can I find Arecibo's data archive? - Astronomy Stack …
2021年5月3日 · 7. Arecibo recently opened the Arecibo Observatory Data Archive, which allows folks to obtain data organized by project. About 1800 proposals are listed, although not all of those have data available because not all of the observatory's data has been transferred to its new home at the Texas Advanced Computing Center.

2023年8月18日 · Another, more distant hope is for the Next Generation Arecibo Telescope (NGAT) to be built at the site. After the 305-metre dish collapsed, some researchers who had used the site proposed NGAT, an instrument that would combine a 314-metre-wide platform with a swarm of 9-metre dishes on top of it.

2019年8月14日 · It is a "delay-Doppler" image, using 12.6 cm, ~500 kW radar broadcasts transmitted by Arecibo. The round-trip light time was about 135 minutes. Because Arecibo has limited steering away from the zenith (<19.7 degrees) max Saturn was only available to the dish for 166 minutes even under ideal conditions.

2021年2月9日 · A description of the design and operation can be found in Multi-feed Systems for the Arecibo Gregorian. This system take rays which would have focused along a line from the spherical reflecting surface and redirects them to come to focus at a point as is desired for reception. According to Moonbounce from Arecibo Observatory:
asteroids - Are we less safe now that Arecibo is no more?
2020年11月9日 · Source: Reddit. update 2: Sadly, parts of the dish have collapsed, several cables have snapped, and the Arecibo radio telescope is now decommissioned and demolition has been recommended because it is now too unsafe to do anything else. NSF begins planning for decommissioning of Arecibo Observatory’s 305-meter telescope due to safety concerns.
Could we carve a large radio dish in the Antarctic ice?
2021年3月13日 · Radio telescope dishes built into fixed surface depressions. At least two very large, single dish telescopes have been built into naturally occurring depressions in local rock: Arecibo at 18.3° N and FAST at 25.7° N latitudes. Both telescope designs have large primary focus structures (small buildings where people can work) suspended high ...

2015年7月10日 · After the commissioning phase that began in 2016, the Five-hundred-meter Aperture Spherical Telescope (FAST) started full operations in 2020. With the loss of the Arecibo Observatory later that year, FAST quickly became even more important than expected. For a number of astronomical objects, it is the only telescope capable of detecting them.
