The Japanese scientists have successfully created the first-ever artificial crater on an asteroid 'Ryugu'. It's a step towards shedding light on how the solar system evolved. The announcement comes after the Hayabusa2 probe fired an explosive device at the Ryugu asteroid early this month to blast a crater in the surface and scoop up material. The aim of blasting the crater on Ryugu is to throw up "fresh" material from under the asteroid's surface that could shed light on the early stages of the solar system. The asteroid is thought to contain relatively large amounts of organic matter and water from some 4.6 billion years ago when the solar system was born. The Ryugu asteroid is around 340 million kilometers from Earth.
