The image captured an area 200 kilometers by 175 kilometers, which almost entirely contains the crater Tycho with a diameter of 86 kilometers.
The most detailed photos of the lunar crater Tycho have been published on the website of the National Radio Astronomy Observatory (NRAO) of the U.S.
Photo with a resolution of five by five meters contains 1.4 billion pixels. They were obtained using the radio telescope observatory Green Bank (GBT), located in West Virginia. This observatory is equipped with new technology to convert radar signals into images. And GBT is the largest fully operated radio telescope in the world today, which was equipped with the new technology late last year. The device, along with telescopes from the VLBA (Very Long Baseline Array) complex, which are located throughout the United States, then captured several portions of the moon’s surface. In his lens hit the crater Tycho and the landing sites of NASA’s Apollo program.
After processing the results of their observations, the scientists obtained the first most detailed image of the surface of our planet’s satellite taken from Earth.
“This is the largest synthetic aperture radar image we have produced to date. While there is still much work to be done to improve these images, we are excited to share this incredible image with the public and look forward to getting more images from this project in the near future,” the release said.
It also notes that every pulse transmitted by GBT is reflected from the moon’s surface, received, and stored.
Associated with the motion are small differences that occur from pulse to pulse of radar, which is used to achieve higher resolution.
“It used to be done at distances of a few hundred kilometers, but not hundreds of thousands of kilometers as in this project, and not at such high resolution,” the scientists concluded.
