Tonight James Keegans informs us of our ultimate demise, and how 'pretty' it will be, and David Benoit explores comets and astroids!
Supernovae, Dark Energy, and Standard Candles
Type Ia supernovas are some of the most spectacular events in the Universe, outshining their host galaxies when they occur. We use them to measure distances to some of the most remote objects in the Universe, however, there are still questions about their exact nature. We will explore some of those questions, and shine some light on one of the brightest astronomical events there is.
Chemistry on a Comet
Dr David Benoit (Senior Lecturer in Physical Chemistry - E.A. Milne Centre, The University of Hull)
Find out why comets and asteroids are really more like big dusty snowballs and how they act as a "mobile chemistry lab" in space. Could our water come from outer-space and has life started by hitching a ride on a comet? Let's find out!
