(June 4) -- Two amateur astronomers spotted an enormous fireball on the planet Jupiter -- and they even caught it on camera.Stargazer Anthony Wesley was watching the sky in Australia on Thursday night when he spotted a huge collision and fireball on the surface of the giant planet, SpaceWeather reported. The collision produced a bright flash of light in Jupiter's atmosphere.Wesley posted the information to an online space forum. Christopher Go, in the Philippines, confirmed Wesley's findings with a video he had shot of the planet."It's rare enough to see a spectacular fireball here on Earth, but no other human being in history has seen one happen right before their eyes on another planet," blogger Bob King, better known as AstroBob, wrote.This is not the first time that Wesley has been ahead of the game in Jupiter watching. Last year, he noticed a huge black spot on the planet's surface, MSNBC reported.Astronomers spent months analyzing the spot before concluding that an asteroid from the Hilda group of space bodies near Jupiter may have struck the planet while it was turned away from Earth.Jupiter is the largest planet in the solar system, more than 1,000 times bigger than Earth. The planet is a giant ball of gas and liquid, with little or no solid surface.Last month, Wesley produced pictures showing that a stripe of dark red clouds in the planet's southern atmosphere had vanished.It is not yet known what caused this recent impact on Jupiter, but amateur and professional astronomers alike will be watching the planet for marks left on the planet's top clouds."Astronomers around the world, both professional and amateur, are scrambling now to get views of the impact site," Emily Lackdawalla of the Planetary Society told AOL News. "Wesley's work shows that you don't need a big telescope to see pretty cool stuff."
A similar impact occurred last July after a large asteroid collided into the planet.
A large object, possibly an  or a , hit the planet Jupiter Thursday, resulting in a large fireball.

The fireball was seen on June 3 at 2031  by two independent amateur astronomers, Christopher Go in the Philippines and Anthony Wesley in Australia. Wesley, who posted the news onto an , is known for having also spotted last July's . Go caught Thursday's impact on video, which showed a fireball the size of Earth after the object hit. It could be the first time someone has recorded a meteor crashing into a planet.

This latest strike came only hours after a team from the , led by astronomer , announced that last year's event was the result of an asteroid 1,640 feet (500 metres) wide. That asteroid caused a scar the size of the  when it hit Jupiter with the force of several thousand nuclear bombs on July 19, 2009.

The planet last experienced a major impact in July 1994, when it was hit by  (SL9), resulting in large scars as well. Scientists originally thought that there would not be any more Jupiter strikes for several centuries following SL9, but have now been proved wrong twice in as many years.

Now, astronomers around the world are trying to figure out what kind of mark Thursday's collision left on the planet, as well as determine exactly what hit it. Although the impact is believed to be relatively small, a dark debris field may soon appear in the clouds around Jupiter, which is what occurred in 2009.
