How did the Universe get so big? Open Night

Join us to celebrate Science Week and the recent announcement of Ireland’s membership of the European Southern Observatory


6pm – 8pm    |     Telescopes vs Eyes    |    Family friendly workshop

Discover how telescopes have changed our understanding of the Universe. How did early astronomers make sense of the cosmos and how has that changed as technology has developed?

A practical, creative session for astro-enthusiasts of all ages.

Drop-in sessions between 6pm and 8pm, stay for 5 minutes or for 30!


7.30pm     |    How did the Universe get so big?    |    BOOKING REQUIRED

The size of the universe as seen through observations from antiquity until the modern era has steadily increased. We will follow our growth in understanding through the observations from Eratosthenes to the most recent discoveries of the accelerating expansion of the universe.


Jason Spyromilio is a senior astronomer at the European Southern Observatory (ESO). His research interests are focused on supernovae and their use in understanding the physics of explosions. He was a member of the high-z team that co-discovered the acceleration of the expansion of the universe (for which they were all awarded the Gruber prize, more recently the Breakthrough prize) and was a member of the ESSENCE collaboration that continued that work. He has participated in work on beta Pic, comets, brown dwarfs, planetary nebulae etc.



7pm    |    Stargazing

Discover the wonders of the night sky with weather dependent star gazing with the Cork Astronomy Club


This is a free open night. Booking is just required for Jason’s talk.



ESO’s VLT reveals the Carina Nebula’s hidden secrets

This broad image of the Carina Nebula, a region of massive star formation in the southern skies, was taken in infrared light using the HAWK-I camera on ESO’s Very Large Telescope. Many previously hidden features, scattered across a spectacular celestial landscape of gas, dust and young stars, have emerged.  You can find more information here
