NASA plans to build an enormous Arecibo-like telescope on Moon?

I don't know if they will rebuild the Arecibo radio telescope, Congress asked for report on Arecibo radio telescope collapse.
The Radio Telescope didnt find little green alien men transmitted radio signals but it contributed to significant breakthroughs in astronomy and cosmology, including the discovery of the first binary pulsar, the first-millisecond pulsar, the first exoplanets, along with helping to study asteroids and planets in the Solar System.

There are plans to put one on the Moon

How about one on Mercury, the Moons of Saturn and Mars?

Re: NASA plans to build an enormous Arecibo-like telescope on Moon?

Mars_B4_Moon, thanks for coming back to the forum and for this new topic.

The news had indicate both a rebuild since china was going to build one but also the nasa thoughts for the dark side of the moon as well now that we plan to go to stay. The cost is the nasa issue....

The lunar farside is the best place in the solar system, because Earth radio transmission is shielded out by 2000 miles of solid rock.  By the way, there is no dark side to the moon.

Building telescopes on the moon could transform astronomy, and it's becoming an achievable goal

"Researchers Discover Twisted Fields Around Mysterious Fast Radio Burst"

https://english.cas.cn/newsroom/researc … 0525.shtml

Fast Radio Bursts (FRBs) are the brightest millisecond-duration cosmic explosions in radio bands. Their unknown origin poses challenges for astronomy as well as physics.

The Commensal Radio Astronomy FAST Survey (CRAFTS), a key program of the Five-hundred-meter Spherical radio Telescope (FAST), discovered the world's first persistently active repeating FRB, known as FRB 20190520B. Now this FRB has provided clues that may help clarify the origin of FRBs.

An international team led by Dr. LI Di from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) carried out a monitoring campaign of FRB 20190520B, using the Parkes telescope in Australia and the Green Bank Telescope (GBT) in the United States. The combined analyses have revealed an extreme field reversal around this constantly bursting source.

China's FAST in the Hunt for Nanohertz Gravitational Waves

https://www.spacedaily.com/reports/Chin … s_999.html

A recent breakthrough in the field of gravitational wave detection has been achieved by scientists in China, who have found vital evidence of nanohertz gravitational waves, thanks to pulsar timing observations performed with the Five-hundred-meter Aperture Spherical radio Telescope (FAST).

The study was spearheaded by the Chinese Pulsar Timing Array (CPTA), a collaborative group of researchers from the National Astronomical Observatories of the Chinese Academy of Sciences and various other institutions. The results of their findings were made public in the Chinese journal Research in Astronomy and Astrophysics.

Gravitational waves are effectively distortions or "ripples" in the fabric of space-time, brought about by the movements of massive bodies such as black holes. Despite their weak signals, these waves are an invaluable tool in detecting the elusive dark matter in the universe.

The detection of gravitational waves of nanohertz frequencies promises profound implications for our understanding of the universe's structure. It could unveil the development, evolution, and merging of the universe's most colossal bodies - supermassive black holes.

Nevertheless, the challenge lies in the detection of nanohertz gravitational waves due to their extraordinarily low frequencies. Their periods can span several years, and their wavelengths can reach up to several light-years. Large radio telescopes conducting long-term observations are currently the only known method for their detection.

Li Kejia, the article's corresponding author and a researcher at the National Astronomical Observatories, stated that the team currently lacks the ability to identify the astronomical sources of the detected signals due to the relatively short observational period of the current data. However, as subsequent observations extend, this issue will be resolved.

The pursuit of nanohertz gravitational waves has captured the attention of physicists and astronomers worldwide. Research teams in the United States, Europe, and Australia have been gathering pulsar timing data for over 20 years. In contrast, Chinese scientists initiated this line of work using FAST in 2019.

The CPTA credits its rapid progress to FAST's superior sensitivity and robust capacity to monitor pulsars. It is noteworthy that their significant breakthroughs align with those achieved by other global research teams, such as the North American Nanohertz Observatory for Gravitational Waves, the European-Indian Pulsar Timing Array, and the Australian Parkes Pulsar Timing Array. These international teams also released comparable results this week.
