British astronomers have taken the first pictures of one of the hottest stars in the Galaxy. The temperature on its surface is 360,032F (200,000C), 35 times hotter than the Sun.

The mysterious dying star at the heart of the Bug Nebula -- 3,500 light years away in the constellation Scorpius -- has never been seen before as it is hidden behind a cloud of dust and ice.

"This star was so hard to find because it is hidden behind a cloud of dust and ice in the middle of the nebula", explained Professor Albert Zijlstra of the University of Manchester.

"Planetary nebulae like the Bug form when a dying star ejects much of its gas back into space and are among the most beautiful objects in the night sky,"

"Our own Sun will do this in about 5 billion years time. The Bug nebula, which is about 3500 light years away in the constellation Scorpius, is one of the most spectacular of all planetary nebulae."
