I hope there is a mcfer who are good in science here to tell us more about it.
Residents spotted a mysterious phenomenon in the sky above the Shortandy village, near Astana, Saturday. Roughly one kilometre (0.6 miles) above ground, a large black ring was floating in the air for around 15 minutes. It then disappeared completely, leaving no trace behind.
