(NASA.RARE. LARGE FORMAT. DEEP SPACE). Bubbles of titanium trigger the explosions of the Titanic. Spectacular and rare photographic picture discovered by scientists and representing titanium fragments escaping from a famous supernova. This discovery, could be an important step in determining the mode of explosion of some giant stars. These are the remains of a supernova called Cassiopeia A (Case A), located in our galaxy about 11,000 light years from Earth. It is one of the youngest known supernova remnants, with an age of about 350 years. For years, scientists have struggled to understand how massive stars - those with masses greater than about 10 times that of the Sun - explode when they run out of fuel. This result provides an invaluable new clue.Vintage chromogenic print. Legend on the back label. 40,6 x 40,6cm with margins.
