Massive satellites "Interference with astronomical observation" February 26, 6:49
Several companies, including the United States, are planning to launch a number of artificial satellites and start a new communications business, and astronomers have raised concerns that they will interfere with astronomical observations.
Several companies in the United States and the United Kingdom are planning new telecommunications businesses for the Internet using massive satellites.
Of these, US companies have already launched 60 launches at a time five times since last year, and finally decided to apply for launching 42,000 launches to the US authorities. It is expected.
There is no organization to coordinate the launch of the satellite, and the International Astronomical Union, which is made up of astronomers around the world, has issued a statement urging that a regulatory framework be urgently created as a hindrance to astronomical observation, and Japan's National Astronomical Observatory has He expressed concern that it was important to work with the research institution to work out a solution.
In the image released by the US Observatory, it appears that more than 20 artificial satellites move while reflecting light as a streak of light, and it was impossible to observe at this time.
In a video of the night sky taken in Kanagawa Prefecture, it was also confirmed that more than 20 artificial satellites passed through like a streak.
"Observations are starting to be affected, and it is certain that the problem will worsen in the future. It is important that researchers and companies work together to solve the problem," said Professor Masatoshi Oishi of the National Astronomical Observatory of Japan. .
