First Images of a Solar Eclipse in Another Solar System

Epsilon Aurigae is about 2,000 light years from earth. Every 27 years, it darkens for two years. With the use of advanced thermal imaging technology, astronomers now think that this event is a solar eclipse:

The eclipse was first observed by the German astrologer Johann Fritsch in 1821.

Dr Ettore Pedretti and Dr Nathalie Thureau, from St Andrews, took part in the research, which was led by Brian Kloppenborg from the University of Denver.

Dr Pedretti said: "From the image, we can confirm that the eclipse of Epsilon Aurigae is caused by a thin disc of opaque dust trailed by a massive and unseen companion.

"Like David, tiny particles of dust are able to kill the light of this 'Goliath' star."
