Where is the cherenkov Telescope Array?
La Palma
The northern hemisphere site is located at the Instituto de Astrofísica de Canarias Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands. The southern site is located at ESO’s Paranal Observatory, around ten kilometres southeast of the Very Large Telescope.
Where is the largest telescope array?
The Atacama Large Millimeter/submillimeter Array (ALMA) is a $1.3 billion collaboration between North America, Europe and Asia, built high on a mountain in Chile’s Atacama desert.
What is meant by a Telescope Array?
A telescope array is a group of telescopes arranged so that, as a set, they function similarly to one giant telescope. This allows astronomers to gather higher quality information, generating high resolution data with great sensitivity to faint signals.
What is a cosmic ray telescope?
Instrument Overview. The cosmic ray telescope used for this experiment was also designed to monitor solar and galactic cosmic rays and track the twisting high energy particles from the Sun. The instrument can determine which of the nuclei of the ten lightest elements make up these cosmic ray particles.
How does Cherenkov telescope work?
A hot pulsar spinning 30 times per second powers the Crab Nebula and serves as a “standard candle” for Cherenkov telescopes. Cosmic rays are accelerated to extremely high energies, traveling close to the speed of light. Cosmic rays constantly bombard the earth, but their sources are still not clear.
What do infrared telescopes do?
infrared telescope, instrument designed to detect and resolve infrared radiation from sources outside Earth’s atmosphere such as nebulae, young stars, and gas and dust in other galaxies.
Can you visit the Very Large Array?
Socorro, New Mexico is the home of our Very Large Array (VLA), where visitors are welcome and encouraged! The VLA includes a visitor center with a theater, science exhibits, a gift shop, and an outdoor self-guided walking tour that takes you right to the base of one of the telescopes! Learn about Visiting the VLA!
Who owns the Very Large Array?
Associated Universities, Inc
The VLA stands at an elevation of 6,970 feet (2,120 m) above sea level. It is a component of the National Radio Astronomy Observatory (NRAO). The NRAO is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
What is the Very Large telescope array looking for?
The VLT operates at visible and infrared wavelengths. Each individual telescope can detect objects roughly four billion times fainter than can be detected with the naked eye, and when all the telescopes are combined, the facility can achieve an angular resolution of about 0.002 arc-second.

How does a cosmic ray telescope work?
It contains six disks made from silicon; they are called solid-state detectors. Such detectors are much more compact than one that uses a gas. A cosmic ray that passes through the detector will create a small current that CRaTER’s computer measures.
What are cosmic rays used for?
Cosmic rays are high energy particles that flow into our solar system from outer space. They are essential for the production of 14C in our atmosphere, which is used in radiocarbon dating, and in the production of cosmogenic nuclides in rocks at the Earth surface, which we use in cosmogenic nuclide dating[1-3].
Who discovered Cherenkov radiation?
Pavel Cherenkov
In certain media the speed of light is lower than in a vacuum and particles can travel faster than light. One result of this was discovered in 1934 by Pavel Cherenkov, when he saw a bluish light around a radioactive preparation placed in water. Igor Tamm and Ilya Frank explained the phenomenon in 1937.
How far can an infrared telescope see?
With balloons, they were able to reach about 25 miles (40 kilometres) up.
How does the James Webb telescope see infrared light?
The longer wavelengths of infrared light slip past dust more easily, and therefore instruments that detect infrared light—like those on Webb—are able to see the objects that emitted that light inside a dusty cloud.
What is the main purpose of the Very Large Array?
The Very Large Array is the most versatile, widely-used radio telescope in the world. It can map large-scale structure of gas and molecular clouds and pinpoint ejections of plasma from supermassive black holes.
How many telescopes are in the Allen Array?

Where is the Allen Array?
the Hat Creek Observatory
The Allen Telescope Array (ATA) is located at the Hat Creek Observatory in the Cascade Mountains of California, approximately 300 miles to the north of San Francisco and two dozen miles north of Lassen Peak.
How harmful are cosmic rays?
Beyond Low Earth Orbit, space radiation may place astronauts at significant risk for radiation sickness, and increased lifetime risk for cancer, central nervous system effects, and degenerative diseases.
Why did Chernobyl glow blue?
Caused by particles traveling faster than light through a medium, Cherenkov Radiation is what gives nuclear reactors their eerie blue glow. In the miniseries “Chernobyl” when the reactor first explodes, there’s an eerie blue light emanating from it.
Why is Cherenkov light blue?
As Cherenkov radiation passes through the water, the charged particles travel faster than light can through that medium. So, the light you see has a higher frequency (or shorter wavelength) than the usual wavelength. Because there is more light with a short wavelength, the light appears blue.
