오늘의 멋진 우주 그림 (2023-06-29)

안녕하세요, 우주 관련 뉴스 입니다. 오늘은 NASA에서 어떤 소식들을 전해줄까요?
우선 이미지를 살펴보도록 하겠습니다!

 

이 이미지 제목은 A Message from the Gravitational Universe 러써. NASA에서 공식적으로 제공한 소개를 살펴보겠습니다.

 

Monitoring 68 pulsars with very large radio telescopes, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has uncovered evidence for the gravitational wave (GW) background by carefully measuring slight shifts in the arrival times of pulses. These shifts are correlated between different pulsars in a way that indicates that they are caused by GWs. This GW background is likely due to hundreds of thousands or even millions of supermassive black hole binaries. Teams in Europe, Asia and Australia have also independently reported their results today. Previously, the LIGO and Virgo detectors have detected higher-frequency GWs from the merging of individual pairs of massive orbiting objects, such as stellar-mass black holes. The featured illustration highlights this spacetime-shaking result by depicting two orbiting supermassive black holes and several of the pulsars that would appear to have slight timing shifts. The imprint these GWs make on spacetime itself is illustrated by a distorted grid. Open Science: Browse 3,000+ codes in the Astrophysics Source Code Library

 

오늘도 광활한 우주 앞에 인간이 얼마나 작은 존재인지 깨닫게 되네요.
저는 내일도 더 좋은 사진과 함께 돌아오겠습니다, 행복한 지구여행 되세요!
