APOD: Night of the Perseids (2021 Sep 28)

Post by APOD Robot » Tue Sep 28, 2021 4:05 am

Image Night of the Perseids

Explanation: Have you ever experienced a meteor shower? To help capture the wonder, a video was taken during the peak of the recent Perseid meteor shower above the Indian Astronomical Observatory in Hanle, India, high up in the Himalayan mountains. Night descends as the video begins, with the central plane of our Milky Way Galaxy approaching from the left and Earth-orbiting satellites zipping by overhead. During the night, the flash of meteors that usually takes less than a second is artificially extended. The green glow of most meteors is typically caused by vaporizing nickel. As the video continues, Orion rises and meteors flare above the 2-meter Himalayan Chandra Telescope and the seven barrels of the High Energy Gamma Ray Telescope (Hagar). The 2 minute 30 second movie ends with the Sun rising, preceded by a false dawn of zodiacal light.

From 1:26 to 1:30, there is a near perfect pentagram at lower mid right. Can anyone tell where that is?

Do you mean the Rho Ophiuchi cloud complex with Antares?

The yellow-orange star at lower left in the pentagram is red supergiant star Antares. The "star" to the right of it is actually not an individual star, but instead a globular cluster, M4. The blue star at the top of the pentagram is Rho Ophiuchi, which has given this cloud complex its name. The star to the upper right of M4 is Sigma Scorpii.
