Remarkable fireball captured breaking on film

A huge fireball was filmed crossing the Australian night sky, before breaking over the Tasman Sea.

The images, captured by the RV Investigator vessel, were taken on November 18, about 60 miles off the southern coast of Tasmania, according to a blog post by Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO). .

“What we saw when looking at the live stream footage amazed us, the size and brightness of the meteor was incredible,” John Hooper, CSIRO’s travel director on board, said in the post. “The meteor crosses the sky directly in front of the ship and then shatters – it was amazing watching the footage and we were very lucky to have captured everything on the ship’s livestream.”

‘EXTRATERRESTRIC ORGANIC COMPOUNDS’ FOUND IN 2018 ‘MICHIGAN FIREBALL’

The livestream, which runs 24/7 from a camera on the RV Investigator, shows the fireball turning a bright green color before splitting apart.

“More than 100 tonnes of natural space debris enters the Earth’s atmosphere every day,” said Glen Nagle of CSIRO Astronomy and Space Science. “Most of this phenomenon remains invisible because it occurs in an unpopulated area like the southern ocean.

“Cameras are everywhere, in our pockets and around our cities, but they need to be pointed at the right place at the right time – RV Investigator was there at this time,” Nagle added.

METEORITE STRIKES MAKE LIFE ON EARTH POSSIBLE

A small piece of an asteroid or a comet is known as a meteoroid. When it enters Earth’s atmosphere, it becomes a meteor, fireball, or shooting star. Pieces of rock that touch the ground, valuable to collectors, are called meteorites.

Last month, researchers discovered that a fireball that entered Earth’s atmosphere in January 2018 over Michigan contained “extraterrestrial organic compounds.”

In 2019, a separate group of researchers suggested that meteorites made life on Earth possible. They identified the isotopes of selenium in rocks in the Earth’s mantle and found identical isotopic signatures inside some meteorites, especially those in the outer solar system.
