A Whoosh And A Bang As Meteor Gives OZ A Miss

Sydney - A large meteor possibly the size of a boulder came close to striking the earth in South Australia state on Thursday night, local media reported on Friday.

Residents of Goolwa and Victor Harbour, south of the state capital Adelaide, inundated police with reports of a flash of blue light, smoke trails and two sonic booms.

Bryan Boyle, of the Anglo-Australian space-watching telescope in the eastern state of New South Wales, told the Australian Broadcasting Corporation that the sightings suggested the object was a meteor which came within 30 kilometres of the ground.

"Occasionally you get a very large size of rock, the size of a stone up to a boulder, and they only occur one at a time," he said.

'It came straight over the top and left a huge smoke trail' Having worked all night, Boyle was unavailable for comment early on Friday.

"It came straight over the top and left a huge smoke trail and there was two huge sonic booms afterwards," a man named Ken told ABC. "It was incredible."

( This is his buddy that went by earlier. Remember the English person who was hit on the foot by a meteorite last week? More to come?)

Stunning asteroid picture revealed

The asteroid above the trail of stars

This is the sharpest-ever picture of an asteroid making a close approach to the Earth.
At the time, the space rock was 400 metres (a quarter of a mile) across and could be seen with binoculars or a small telescope.

The nearest it came was 750,000 kilometres (466,028 miles) of the Earth - twice the distance to the Moon.

Astronomers say the asteroid, known as 2002 NY40, posed no danger to life on Earth.

But if it had hit our planet, the force would have been equivalent to that of several nuclear bombs.

Twinkling stars

The pictures were taken by the William Herschel Telescope on La Palma, Canary Islands, on the night of 18 August.

They are the first images of an asteroid taken with an Adaptive Optics System.

The technology was built by a team from the University of Durham and the UK Astronomy Technology Centre (UK ATC).

It allows ground-based telescopes to deliver images as good as those taken from space.

It does this by using mirrors to correct for the blurring of starlight caused by turbulence in the Earth's atmosphere.

"In future, this is going to mean the giant telescopes that are coming into operation will be able to produce sharper images than can be produced by the Hubble Space Telescope," said Colin Cunningham of the UK ATC.

'Collision course'

Space objects come this close to Earth only once every 50 years or so.

It is a rare opportunity to study the nature and potential threat of the fraction of asteroids that approach the planet.

"Getting more detailed data on objects such as this will help us to understand more about their nature and how to deal with one should it find itself on a collision course with Earth," said Kevin Yates of the UK Near Earth Object (NEO) Information Centre.

"A 400-metre asteroid would probably wipe out most of England if it hit," he told BBC News Online.
