NASAさんのインスタグラム動画 - (NASAInstagram)「Feeling existential this #BlackHoleWeek? We invite you to take a break and listen to the not-so-soothing sounds of the black hole at the center of the Perseus Galaxy Cluster! Video descriptions: 00:00 Zooming in on the X-ray image of Perseus galaxy cluster in shades of light blue. The center glows bright white and the hot gas around the center is light blue, fading to a darker blue at the edges. The gas swirl is brighter at the center showing that the gas is hotter, but as the gas gets farther from the center, the bright tendrils dim into a deeper blue showing dissipation of the gas. The words “Feeling existential during #BlackHole Week? Check out these sounds from the black hole at the center or Perseus!” appear on screen in white. 00:11 The same image of Perseus appears in shades of orange and purple with the center being bright white, then orange, and finally purple on the edges. The words “This black hole created pressure waves that made ripples in hot gas,” appear in white. 00:22 The image of the Perseus galaxy in orange and purple fades to shades of pinks, purples, and blues. The words “which were then translated into notes we can hear!” appear in white.」5月2日 4時00分
