- telescope - What will succeed the Arecibo Observatory? - Astronomy . . .
The Arecibo Observatory has proposed a phased array of small dishes mounted on a circular platform ~300 meters in diameter (or potentially multiple smaller platforms) which would be angled in various directions to provide reasonable sky coverage
- Where can I find Arecibos data archive? - Astronomy Stack Exchange
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
- radio telescope - How could the loss of the Arecibo Observatory have . . .
NSF has, for years, tried to kill off Arecibo, but it's effectively been saved by the review panels they were required to convene to make policy decisions The cables snapping gave them an "out" and that could be part of the reason behind the decision to decommission it $\endgroup$ –
- Could we carve a large radio dish in the Antarctic ice?
Arecibo succumbed to deterioration of its cables caused by environmental factors and fell down Is there any role today that would justify building a large single dish radio telescope to replace Arecibo? What will succeed the Arecibo Observatory? How could the loss of the Arecibo Observatory have been prevented?
- asteroids - Are we less safe now that Arecibo is no more? - Astronomy . . .
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
- observational astronomy - Next Generation Arecibo Telescope (NGAT . . .
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
- Building a floating, ocean-going giant radio telescope?
The leading radio telescopes have their mirrors and receivers very exactly aligned For example, Arecibo's Gregorian dome could be aligned with any location on the order of millimeters, while the Green Bank Telescope's mirrors are aligned to the tenth of a millimeter I would certainly be concerned about replicating this performance in the ocean
- radio astronomy - How did Arecibo detect methane lakes on Titan, and . . .
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
- Mysterious radio signals - how could a geostationary satellite and . . .
For Arecibo, I calculate about -3 2° declination QUESTION: How could a radio telescope have picked up satellite signals from a satellite at about -3 2° declination while observing a star at +0 8° declination? And why wasn't this immediately ruled out - surely radio telescopists know about satellites by now, especially the crowded ring of
- Is there an advantage to the equatorial region of the far side of the . . .
Since you are asking about single craters I assume this question is about using a crater as a natural pre-form for a single, large dish antenna like Arecibo Observatory and FAST On the Moon with no atmosphere or ionosphere nearly the whole sky is available for good signal, but as you move away from the current zenith position (i e "straight
