Everyone in Northern Ireland will be able to see a fairly rare event early on the Thursday morning, if the sky is clear.
The Full Moon will pass directly in front of Mars, an event called an occultation from the Latin word occult, meaning hidden.
Mars appears like a very bright red star and is very prominent high up in the sky later in these evenings, as it is now at "opposition", or opposite to the Sun in the sky, and at its closest to the Earth for the year.
