Cardiff Scientific Society: Lighting Up The Dark – The Infrared Universe Seen By The Herschel Space Observatory

10/01/2018, 19:00 - 20:00

Members only but membership can be bought at the event (£15 adults, free under-18s)

Speaker: Professor Haley Gomez (Cardiff University)

Dust contains roughly half the heavy elements in the interstellar medium today, and is responsible for obscuring almost half of the energy emitted by stars since the Big Bang. This light is re-emitted in a region of the electromagnetic spectrum that was, until recently, relatively unexplored. The Herschel Space Observatory, launched in 2009, provided a unique opportunity to resolve this by directly tracing the total mass of dust in more than half a million galaxies. This has allowed us to survey the peak of the dust emission in galaxies both near and far, providing a census of dust in galaxies throughout cosmic time. I will cover some of the highlights from Herschel’s surveys of galaxies and its revealing of where dust is made in the universe.

Cardiff Scientific Society

Cardiff Scientific Society is a members only, non-profit making organisation that retains the aims set out when it was founded in 1926, “By Lectures, Demonstrations, etc, of a popular nature, to extend interest in the application of Science to everyday life.”

The Society runs a series of lectures on scientific topics throughout the year. These are aimed at anyone with an interest in science. Lectures are members only but membership can be bought online, by post and at the door.

Single lectures can be attended for a £5 fee or a Membership can be purchased to cover the whole year. Current fees are £15 for adult members. Young members (18 and under) and Students can join for free.
