ATV – Jules Verne

The book, From the Earth to the Moon written by Jules Verne, describes firing the explorers from a canon to reach the Moon. This video explores Newton’s equation for gravitational force and how these forces change over distance. Anu Ojha explains how the International Space Station is in freefall, and how this...

ATV – Johaness Kepler

This video explains the historical context of observations and the different models of the solar system, that led to Kepler’s theories of elliptical planetary orbits. Both the Copernican and Ptolemaic models required the use of epicycles to explain retrograde motion. Kepler spent six years developing his three...

ATV – Georges Lemaitres

This video explains how Lemaître theory of the Big Bang explained the measurements made from the early 20th Century until today. The presenter, Anu Ojha, explains how different elements have different spectra because of the changes in energy levels of the electrons in the atoms. Spectroscopy of many nebulae show a...

ATV – Amaldi

The physicist Edoardo Amaldi was instrumental in the development of CERN and of ESRO, which eventually became the European Space Agency. One of the European Space Agency’s Automated Transfer Vehicles (ATV) is named after him. This video focuses on the low Earth orbit radiation environment and cosmic rays. The...

ATV – Albert Einstein

With the aid of animations, in this video, Anu Ojha explains Einstein’s theory of Special and General Relativity. Special Relativity tells us that the speed of light is constant, and therefore the measurements of space and time will change from the perspective of different observers. General Relativity tell us...

Atacama Desert

Astrobiologist Dr. Lewis Dartnell talks from the Atacama Desert about a research trip to find extremophiles that might give scientists some clues as to the kind of life that may exist on the surface of Mars.  Lewis shows how quartz can act as a natural sunscreen to enable cyanobacteria to grow in the dry desert...

Astronauts on 'Space Walk' from the International Space Station

This vertiginous video clip , from Footagevault, shows an astronaut emerging from the Quest airlock on board the International Space Station. Further views recorded from a small camera mounted on the astronaut's helmet show the astronaut-eye view of his spacewalk, looking around the outside of the Space Station...

Astro Pi Worksheet

This simple worksheet explains the inputs, sensors and outputs on the Astro Pi board. It contains a section for students to fill in with their ideas and a description of what they would use the Astro Pi for on the International Space Station.

Astrobiology

Dr Claire Cousins and Mark Fox-Powell explain how scientists look at life that exists in extreme environments on Earth, to see what kind of life scientists might see on the surface of Mars.  This knowledge helps scientists plan the best target for a rover.

Professor Cockell takes us through the astrobiology...
