The International Space Station will be a regular visitor in the Northern Ireland skies in the coming weeks - and the exact times you should look up have been revealed.
The ISS, which appears as a bright glowing object, looks like a fast-moving plane or star moving across the horizon usually from the west.
It is currently habited by a crew and orbits at a height of about 264 miles, traveling around the earth 15 times a day.
The ISS has been in space for more than 6,000 days, during which time it has completed around 100,000 orbits of Earth, and has been continuously occupied for more than 13 years.
And, weather permitting, it will be visible above Northern Ireland over the next fortnight:
