The International Space Station (ISS), now the second brightest object in the night sky, is currently passing over Ireland in the very early morning (or very late evening!) - around 2 to 3 am each day - for the next couple of weeks.
This link takes you to the Heavens Above website where you can see the times of the ISS passes (and other interesting information, like for example times for iridium flares).
This link is set for Armagh.
If you live anywhere else please remember to change the location.
The above photo is one of the most dramatic Earth-science photos ever taken from space. It was taken on 12 June 2009 by the Expedition 20 crew from NASA's International Space Station, when it flew just directly overhead Russia's Sarychev Peak volcano which was erupting for the first time in 20 years.
