One-minute journey to the heart of the Milky Way. Video by @babaktafreshi & @esoastronomy
The World at Night project
We begin this on a photograph of a starry night in California with the setting moon shining on sandstone rock formations. My colleagues at the European Southern Observatory (ESO) announced an exciting discovery a few days ago. Direct observation of Einstein’s general relativity on a star very close to the 4-million solar mass black hole in the Galactic Center. The swarm of stars orbiting rapidly around the supermassive blackhole have been observed for about 3 decades, leading to this discovery. The second part of the video, created by ESO, is a combination of telescopic images, all the way to some of the world’s largest ones called the VLT (Very Large Telescope). Follow me @babaktafreshi to explore more of astronomy & space photography.
