Accounts of occasional celestial spectacular events in past centuries have provided crucial information for modern-day astrophysicists. One such example is the so-called Great Eruption of Eta Carinae which was for a time in the mid 19th century the third brightest object in the night sky.
Drones are changing the face of war in the 21st century for combatants and civilians. Today drones carry out targeted assassinations, bombings and intelligence-gathering, and the forces that deploy them aim to minimise the loss of life.
Charles Edward Stuart (‘Bonnie Prince Charlie’) is one of the most recognisable and romanticised figures of British history. Born in Rome as a Catholic prince on 31 December 1720, he led the Jacobite Rising of 1745, which came closer than anyone expected to changing Great Britain irrevocably.
Well-trained eyes can be remarkably useful for capturing light curves of evolving objects in the cosmos, even contributing to modern research programmes.
At longer wavelengths than the normal optical wavelengths to which human eyes are normally sensitive, is the radio part of the electromagnetic spectrum.
Mars has changed since it formed 4.6 billion years ago. When life started on Earth ~4 billion years ago, Mars was habitable too, with volcanism, a magnetic field, surface water and a thick atmosphere. Today, Mars is cold and dry, with a thin atmosphere and harsh surface.
This talk will consider how expectation plays a role in discovery and in scientific advance, and considers the challenges involved in assessing changes taking place on our own planet.
This lecture will present the endeavours of cosmologists and particle physicists, as they attempt to explain the fundamental nature of these mysterious dark components.
