Researchers at the University of Leicester will be peeling back the hidden layers of the universe and exploring what lies beyond the lens of the telescope at a free public lecture on Thursday 23 April.

Organised by Dr Sarah Casewell from the Leicester Physics Centre, the lecture, entitled ‘The Universe through many lenses’, seeks to explain how much more of the universe can be revealed in the future by using pioneering scientific techniques.

In the last 25 years the Hubble Space Telescope has produced images that form much of what we know about the many galaxies that make up the known universe.

However, these images only cover a tiny amount of the electromagnetic spectrum.

The lecture will explore how images acquired in other wavelengths, from the radio to gamma rays, can produce larger images of the universe that go beyond the Hubble Space Telescope.

Using this information allows for further insights to be gained about the future of astronomy and space exploration.

Dr Casewell explained: “By observing in different wavelengths we can see so much more of the universe and probe deeply into regions which are hidden from the naked eye. Often these images aren’t used by the media in favour of images taken in visible light, which is a shame, as often they are much more revealing about what is actually happening!”

2015 is the International Year of Light, which highlights the topic of light science and its applications and the importance of raising global awareness about how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture and health.

Leicester Physics Centre lectures are sponsored and paid for by the East Midlands Branch of the Institute of Physics.

The free public lecture ‘The Universe through many lenses’ will be presented by Dr Sarah Casewell on Thursday 23 April 2015 at 18.30 in Lecture Theatre 2 in the Bennett Building at the University of Leicester.
