Stargazers will have another opportunity tonight to see an apparent close encounter between Mars, Venus and the moon, weather permitting.
The so-called conjunction will see all three appear brightly in a triangle in the night sky.
Venus has been closing in on Earth and Mars since December, and the two are now at their very closest point.
Mars is now around 277 million kilometres from Earth and Venus is 80 million kilometres away.
As a result, Venus, which is around the same size as the Earth, has been appearing increasingly bright.
Of course while the planets will still be huge distances apart in space, the line of sight effect makes them look much closer.
According to Astronomy Ireland, Mars is plainly visible to the naked eye just to the upper left of Venus, but is not as dazzling because it is 3.5 times further away from Earth than Venus, and much smaller than Venus.
Sky watchers in some parts of the country reported good viewing conditions for the conjunction last night, with many photos and videos appearing online.
However, if you missed it last night and if the weather isn't good tonight, you will have plenty of opportunity over the next 10 days to see it, as the planets will only be drifting apart gradually.
An extremely inhospitable planet, Venus has surface temperatures of 550 degrees Celsius, and is covered in clouds that contain sulphuric acid - the same material found inside batteries.
Astronomy Ireland will hold a free event at its Dublin headquarters at 7pm this evening to enable members of the public to view the phenomenon through its telescopes.
