...solar nebula that gave birth to the Solar System, preserving the composition of this original material. In contrast, processed samples have been altered by heat. They are from larger bodies and contain information about planetary surfaces and interiors. [Meteorite piece weighing about 4g] Meteorite piece weighing about 4g The stones that fell over Winchcombe are from the...

...energy source at its heart...The field of active galaxies is recognised as one of increasing importance. But how do we know there are different kinds of galaxy? What are active galaxies? How are they powered? This free course, Introduction to active galaxies, examines the different types of active galaxies and looks at the crucial role of the active galactic nucleus and...

...equip space missions with the technology they need to analyse the planets? Or how pieces of space rock can be picked apart in the laboratory to tell us about the history of the Solar System? In this collection you will learn how early career scientists within the School of Physical Sciences carry out research to learn more about the world, and space, we live in....

...solar system. Moons are certainly plentiful in our solar system – the four giant planets host over 200 moons between them. Even Saturn’s largest moon, Titan, has a radius that is less than 5% that of its parent planet, and while it’s true that the Earth and moon have a size ratio of about four to one, they are both rocky bodies. The Earth-moon system formed as a...

...Energy and Sustainability. ...Transport and Sustainability: Introduction - Transport has considerable environmental impacts. It creates problems of urban air pollution and greenhouse gas emissions. There is also the problem of determining who is the most important urban road user; the private car, public road transport, or cyclists and pedestrians. The ultimate energy...

...energy use might come from. Long run we will probably see some improvements in solar technologies maybe solar thermal maybe some improvements in photovoltaic manufacturing and hopefully some big improvements in photoelectric chemistry. But they are pretty far away. I hope we will see more geothermal, wind of course is ready and I think we need to see a lot of wind. One of...
