A stewardess captured stunning video of an exceptionally bright meteor while "handing out sandwiches" on a flight.

Sasha Bashnya wrote on her Instagram page, "Money comes and goes, but I will never again be 22-year-old-me watching a meteor from a porthole."

The bright green object was spotted blazing through the skies over Moscow on the evening of October 27. Some Muscovites believed President Putin was testing a 9M730 Burevestnik nuclear-powered cruise missile. But that wasn't the case.

According to the Metro, head of the Space Research Institute of the Russian Academy of Sciences, Sergey Bogachev, says that "fireballs" can be spotted on a regular basis -- if you know where to look.

Geologist Sergio Almazán shared a video of the same bright meteor, also known as a bolide, rocketing across the rooftops of Moscow.

When a meteoroid, which is a chunk of rock or metal from space, enters Earth's atmosphere, it's moving incredibly fast -- usually between 11 and 72 kilometers per second. At those speeds, the air in front of it doesn't have time to move out of the way. Instead, it gets compressed. That compression heats the air to extreme temperatures -- thousands of degrees Celsius -- which in turn heats and vaporizes the outer layers of the meteoroid. The glowing streak is the superheated air and vaporized material around it, emitting light.
