Caption: Comparing young star, artwork. Young stars range in size, colour and lifespan depending on their initial size. Small red dwarf stars (bottom left, around 0.1 solar masses) burn for hundreds of billions of years. Low-mass yellow dwarf stars such as the Sun (lower left) last some 10 billion years. Massive B-type blue stars (centre, around eight solar masses) only last around 10 million years. In the background is part of the star R136a1 (around 300 solar masses), discovered in 2010 by instruments on ESO's Very Large Telescope. It is a blue hypergiant star, also classed as a Wolf-Rayet star, and the most massive star yet observed.Restrictions:
