Stargazers are waiting anxiously to see if an icy comet survives a close encounter with the Sun and fulfils its billing of being “one of the brightest of the century”.
Comet Ison is to pass the star at a distance of just 727,000 miles, where it will meet temperatures of around 2,700C (4,892F), leading to predictions it will break apart before it can be seen blazing in the night sky.
It is expected to get closest to the Sun at 6.37pm UK time.
Scientists will be watching to see if the comet , which left the outer edge of the solar system more than 5.5 million years ago, disintegrates under the intense heat and gravitational forces of the Sun.
