You better watch out, keep looking to the sky, give the horizon a scout, and I’ll tell you why - Wirtanen is coming to town.

A 'Christmas comet' is set to pass unusually close to Earth this December, according to Astronomy Ireland.

Three celestial events will coincide in our skies tonight, putting on a spectacular display for stargazers.

After 12 years in space, two of which have been spent conducting scientific operations on the comet, Rosetta will conclude it's mission on 30 September by crash landing on the surface of comet 67P/Churyumov–Gerasimenko.

Air surrounding the comet where a European probe landed last year is rich with oxygen, scientists have learned.

The Philae spacecraft which landed on a comet last year may have shifted position, making it harder to communicate with the probe, scientists said.

Comet lander Philae may be sitting on an object teeming with alien microbial life, according to two leading astronomers.

A modest pick-up in sales at electricals firm Comet was overshadowed today by continued pain at its owner’s French business.

Comet owner Kesa today said strong demand for items such as flat-screen televisions boosted trading over the key Christmas period.
