We're talking about the study of other planets in the solar system, and we do not know many things about our earth. Один из наименее загадочных и неизученных регионов – Антарктида. Only a year ago, a group of scientists from several countries have found the lake and the largest canyon in the world on this continent. They did it, analyzing satellite images, collected by NASA, ESA and the National Data Center on snow and ice USA. 
Researchers from the UK, USA, Australia and China, who carefully analyzed the satellite data, They reported their discovery in the journal Geology website. According to their data in Antarctica has the largest canyon in the world (twice as much of the Grand Canyon in the United States). If you delve into the details, it is a system of canyons longer 1000 km and a depth of more than a kilometer (in some places). Canyon glaciers formed in a thickness of several kilometers.
canyon system is one of the most mysterious places on the planet: Princess Elizabeth Land, East Antarctica. Because of the rare research, carried out in this area, about this place humanity knows the least. But, будем надеяться что в ближайшем будущем удастся приоткрыть тайну Антарктиды, as new research planned mainland. Do not stand aside, and Ukraine, we plan to create a map of Antarctica, Read more here https://www.kmu.gov.ua/ua/news/vidteper-nanc-vivchatime-antarktidu-z-kosmosu-pidpisano-vidpovidnij-memorandum.
This is not the end of the news. According to scientists, who conducted the study, canyons may be associated with subglacial lake. researchers say, Reservoir that undetected area can be 12,5 quarter. km. Further studies are planned to determine the size of the canyon and lake. These will include surveillance aircraft, and further analysis using GPR systems. That includes transmitting radio waves through the ice and snow, are used to determine hidden patterns of the reflected wave. On their basis it is possible to develop a map of the area.
Антарктида – пятый по величине континент. It has an area 14,0 millions of square kilometers. It is the coldest and driest region on the planet. Due to climatic conditions, it is the only continent in the world with no permanent residents.
