Two huge radio telescopes gave scientists a rare opportunity to look under the surface of the moon and answer some questions that hadn’t given them any peace for a long time.
Radar signals from the Arecibo Observatory in Puerto Rico, the world's largest radio telescope with a diameter of 304 meters, were able to penetrate deep into the moon. They were then reflected from the surface of the natural satellite of the Earth and were received by the Green Bank telescope in West Virginia - the largest, fully controlled radio telescope of 100 meters in diameter.
Using a method called bistatic radar, the researchers expect to explore many objects in our solar system, from asteroids to other planets. In this case, the researchers looked under the surface of the moon in two places - the Sea of Tranquility and a crater called Aristillus.
In the Sea of Tranquility, which is located next to the placewhere NASA’s manned lunar module landed in December 1972 as part of the Apollo 17 mission, scientists were able to “dive” to a depth of 10 to 15 meters. The light and dark areas seen in the images are areas of stone and dust.
The radar images also forced researchers to take a fresh look at the crater Aristillus, whose diameter is about 54 kilometers and its depth reaches 3.5 kilometers.
As stated by representatives of the National Radio Astronomy Observatory, who work with the Green Bank telescope, the dark circuit surrounding the crater is due to the presence of dusty debris. The image also shows traces of lavender-like rocks formed, apparently, during the melting of the lunar surface.
"These images will help scientists interpret the complex history of the moon, which is often hidden by layers of dust accumulated over billions of years. In addition, they will allow you to better understand the geology of early landing sites and, without a doubt, will significantly improve the plan for the future exploration of the moon," Researchers British Internet edition of Mail Online.
