NASA. DEEP SPACE. LARGE FORMAT. Titanium bubbles trigger Titanic explosions. Scientists have discovered a rare and spectacular photographic image of titanium fragments escaping from a famous supernova. This discovery could represent an important step towards determining how certain giant stars explode. These are the remains of a supernova called Cassiopeia A (Cas A), located in our galaxy some 11,000 light-years from Earth. It is one of the youngest known supernova remnants, with an age of around 350 years. For years, scientists have struggled to understand how massive stars - those with a mass greater than around 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 back label. 40.6 x 40.6cm with margins.
