A space angel? No, the merger of two cosmic giants

This galactic crash took place in the VV689 system in the constellation of Leo. The delicate wings were formed when the two gravitationally bound objects collided and generated 'angel wings' in a Hubble Space Telescope image.

They find all the building blocks of life in meteorites from outer space

Scientists have found the 'building blocks of life' in three meteorites that fell to Earth in 1950, 1969 and 2000. They all contained compounds that have been previously detected but also cytosine and thymine, the building blocks of life. This discovery adds to the evidence suggesting that the precursors of life came from space.
