The formation of exoplanets

...System. These include ‘hot Jupiters’ orbiting very close to their parent star and rocky ‘super Earths’ many times larger than our home planet. In this free course, The formation of exoplanets, you will learn about the challenges connected with efforts to reconcile the observed exoplanet population with current theories on how planets form. The two main theories...

Explainer: Einstein's Theory of General Relativity

...system in which acceleration can be due to either gravity or changes in velocity? It seems to depend on how you are looking at it. That led to the idea of a “reference frame” – the stage on which the objects you are looking at play out their roles. There may of course be other frames in which the objects appear to behave differently, so we need a description of all...

The hostile environment for immigrants is drawn from a well of taken-for-granted assumptions

...system to take account of the diversity of the population it ostensibly serves. The hostile environment to immigration is only one of a series of hostile environments established by the current Government. The disabled, single parents, unemployed, those who rely on benefits have all been treated, in one way or another, to versions of the hostile environment. The Ken Loach...

...systems. Pathological ageing is being often referred to as speeded-up ageing, where due to some missing components (self-repair functions, quickly advancing changes in neurotransmitters and neurones; significantly increased presence of plaques and tangles in the brain; or chronic inflammations) the decline of our brain progresses faster when compared to physiological...

...system, some other sectors and embedded in imports have fallen as the UK and other countries attempt to move towards net zero. According to official statistics, by 2019 total UK consumption-based emissions were 774 million tonnes CO2e (Figure 1) meaning that the average carbon footprint was about 11.6 tonnes CO2e/person/year. By 2022 the average footprint is estimated to...

...system and is a leftover from our planetary formation process. As the comet gets closer to the Sun and becomes heated, the ice can turn straight to gas carrying dust particles out into space. The gas and dust create impressive tails that can reach up to millions of kilometres in length. [Comet C/2020 F3 (Neowise) photographed during July 2020 in the northern sky]Figure 2...

...System bodies from contamination by Earth life and protecting Earth from possible life forms that may be returned from other Solar System bodies.​ Approaches to this taken by space agencies and mission teams have changed over the 60 years of Mars exploration and will continue to adapt to new scientific understanding of the planet and of life itself. However, the central...
