Dr. Steve Barret

Dr. Steve Barrett from the University of Liverpool gave two short presentations:
Just a Second – What is a second, what can happen in one second, and why do we need leap seconds?
Ancient Light – The Universe is vast and ancient. Large telescopes have imaged galaxies that are billions of light-years distant. Is it possible to capture an image of one of these very remote objects without a telescope?
