아름답고 멋진 우주사진 2021년 12월 07일

2021년 12월 07일자 도착할 우주여행 장소는 사진에 나온 장소입니다.

여기는 Ninety Gravitational Wave Spectrograms and Counting 입니다. 

 

 

very time two massive black holes collide, a loud chirping sound is broadcast out into the universe in gravitational waves. Humanity has only had the technology to hear these unusual chirps for the past seven years, but since then we have heard about 90 -- during the first three observing runs. Featured above are the spectrograms -- plots of gravitational-wave frequency versus time -- of these 90 as detected by the giant detectors of LIGO (in the USA), VIRGO (in Europe), and KAGRA (in Japan). The more energy received on Earth from a collision, the brighter it appears on the graphic. Among many science firsts, these gravitational-radiation chirps are giving humanity an unprecedented inventory of black holes and neutron stars, and a new way to measure the expansion rate of our universe. A fourth gravitational wave observing run with increased sensitivity is currently planned to begin in 2022 December.

 

멋지고 아름다운 우주여행에 탑승해주셔서 감사합니다.

다음에도 멋진 장소로 모실 수 있도록 노력하겠습니다.
