A ball of fire. Astronaut captures mysterious green flash in space

A NASA astronaut has managed to capture a mysterious flash in space. Matthew Dominick is currently on the International Space Station, so he has excellent conditions for observing unusual objects outside the Earth.

The astronaut notes that he noticed a green "streak and then an explosion" outside the ISS. This space wonder has raised many questions, writes TheSun.

In slow motion, a white-green explosion over the Mediterranean Sea is clearly visible, lasting a split second, completely obscuring everything around.

Matthew Dominic was impressed by the footage himself, so he turned to his friends for an explanation of the strange phenomenon. "I showed it to a few friends. They thought it was a meteor exploding in the atmosphere – a fairly bright meteor called a bolide," the astronaut wrote on his X network page.

Dominic set up a time-lapse on his camera over North Africa, where it was very dark and thunderstorms were occurring at the time. That's why the flash is clearly visible. "Slow motion slows down to one frame per second so you can see its streaks and then breaks," the NASA astronaut added.

According to scientists, a bolide, also known as fireballs, is an astronomical term for exceptionally bright meteors that can be seen over a very large area.

"I think it's interesting to compare the size of a bolide explosion to other objects that are visible like the Mediterranean Sea, Cairo, or lightning strikes," Dominic suggested.

Jeffrey Smith, a data scientist at the SETI Institute and principal investigator of the Asteroid Threat Assessment Project at NASA, noted that only a "couple" of cars are spotted every year.
