NASA-聆听太阳系以外的5,000世界🔊本周，我们宣布，我们现在已经确认存在超过

案例简介：聆听太阳系以外的5,000世界🔊本周，我们宣布，我们现在已经确认了5,000多颗系外行星的存在，或者已知存在于我们的恒星系统之外的行星。从地球大小的岩石小行星到比木星大数倍的气态巨行星，我们已经寻找了30多年的时间来寻找这些外行星的微妙信号: 当一颗行星从它前面经过时，一颗遥远的恒星变暗，或者恒星运动从其行星引力的微小变化。借助 @ NASAWebb等新型望远镜和尖端技术，我们发现了比以往更多的世界-甚至开始捕捉直接图像。我们了解到银河系可能有数千亿颗行星!这个视频是所有5,005确认的系外行星的声音，随着时间的推移，它们的发现变成了音乐般的声音。当发现每个系外行星时，一个圆圈会出现在它在天空中的位置。圆圈的大小表示行星轨道的相对大小，颜色表示使用哪种行星检测方法来发现它: 粉红色对应于径向速度，紫色对应于行星过境，绿色对应于微透镜，红色对应于时序变化，黄色对应于轨道亮度调制，灰色对应于天体测量，和蓝色到磁盘运动学。音乐是通过为每个新发现的世界演奏音符而创建的。音符的音高表示行星的相对轨道周期。需要较长时间绕恒星运行的行星被听到为较低的音符，而较快绕轨道运行的行星被听到为较高的音符。信用: NASA/jpl-caltech/M。Russo, A.Santaguida (系统声音) # NASA # 太空 # 天文学 # DataViz # Sonification # awholeenewworld

NASA-聆听太阳系以外的5,000世界🔊本周，我们宣布，我们现在已经确认存在超过

案例简介：Listen to 5,000 worlds beyond our solar system 🔊This week, we announced that we have now confirmed the existence of over 5,000 exoplanets, or planets known to exist outside of our home star system. From small, rocky Earth-sized worlds to gas giants many times larger than Jupiter, we've been looking for more than 30 years to find these exoplanets' subtle signals: the dimming of a distant star as a planet passes in front of it, or a small shift in the star's movement from its planet's gravity.With new telescopes like @NASAWebb and cutting-edge technology, we're discovering more worlds than ever—and even starting to capture direct images. We're learning that there are likely hundreds of billions of planets across the Milky Way!This video is a sonification of all 5,005 confirmed exoplanets, turning their discovery over time into music-like sound. As each exoplanet is discovered, a circle appears at its position in the sky. The size of the circle indicates the relative size of the planet's orbit and the color indicates which planet detection method was used to discover it: pink corresponds to radial velocity, purple to planetary transit, green to microlensing, red to timing variations, yellow to orbital brightness modulation, gray to astrometry, and blue to disk kinematics.The music is created by playing a note for each newly discovered world. The pitch of the note indicates the relative orbital period of the planet. Planets that take a longer time to orbit their stars are heard as lower notes, while planets that orbit more quickly are heard as higher notes. Credit: NASA/JPL-Caltech/M. Russo, A.
