Weather scientists find one of worlds largest hail stones
By SUSAN MCGUIRE, Daily Mail, August 24, 2015
Scientists have found that the surface of a massive meteorite hit one of Earth’s biggest asteroids during its final few days before striking Earth in 2013.
A powerful ‘Hailstone’ strike in December 2013 left one asteroid – named ‘Antares-H’ – completely scarred, revealing its interior.
One month later scientists said they had managed to detect a rare earth metal (REE) – a material scientists believe was thrown off the giant asteroid in December 2013.
Now scientists are investigating possible impacts on smaller asteroids, according to a study by researchers at the Southwest Research Institute in Colorado.
They say a ‘Hailstone’ impact on a larger object – such as an asteroid – will출장만남 reveal detailed evidence about the origin of the impact on an asteroid that is now only 1.5 kilometres across.
It is thought that such massive asteroid impact marks are unlikely to occur on Earth again for hundreds of millions of years.
The researchers – based at the University of Colorado and at a handful of U.S. universities – say they have found this rare element in a sample of older Earth minerals that were picked up in the atmosphere above the impact site.

However, when the researchers checked on the sample this month they discovered the meteorite’s surface was no longer visible.
They believe this was due to heat from the impact which shattered the meteorite’s surface and then melted it.
