Chargaff's ratio

This animation looks at research which led to solving the structure of DNA.  In 1950, Erwin Chargaff published a paper stating that in the DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This became known as Chargaff's ratio, and it was an important clue...

Paired DNA strands

This animation illustrates the DNA double helix structure. If untwisted, DNA looks like two parallel strands. Each strand has a linear sequence of A, C, G, and T. The precise order of the letters carries the coded instructions. One strand is a complementary image of the other: A always pairs with T, and C always...

Very Large Telescope

From the European Southern Observatory (ESO), this video describes the construction and work of the Very Large Telescope (VLT). The VLT was made in Europe and will be erected on Cerro Paranal, a 2,640 metre high mountain in the Atacama desert in northern Chile. This video describes the VLT project and some of the...

Tim Peake

This video is a message to ESERO-UK from European Space Agency astronaut Tim Peake. He talks about studying STEM subjects and how he became an astronaut. The video includes images of a launch, Tim engaging in various astronaut training exercises and the International Space Station, where Tim will be for six months...

The Orion Nebula

The Orion Nebula reveals many of its hidden secrets in the dramatic images taken by the European Southern Observatory's VISTA survey telescope. This video showcases some of them and describes some of the processes occurring in the Orion nebula. VISTA (the Visible and Infrared Survey Telescope for Astronomy) is the...

The Life Cycle of Stars

In this Teaching Astronomy and Space video, produced by the Institute of Physics, Teachers TV and Science and Technology Facilities Council (STFC), astronomer Tim O'Brien, from Jodrell Bank Observatory, explains how astronomers believe a star is born, lives and dies. Tim compares the life of stars like our Sun...

The Benefits of Bringing Space to the Classroom

Filmed at the ESERO-UK Secondary Conference, in 2014, this video shows teachers talking about the benefits of attending the conference, networking with other teachers and learning about the different contexts that can be used to teach STEM subjects. The video also features UK European Space Agency astronaut Tim...

Spaceflight History: High Altitude Parachute Test

Produced by FootageVault, and using original NASA video, these clips chart the first high altitude balloon flight of Joe Kittinger during Project Excelsior. This was a series of high-altitude parachute jumps made in 1959 and 1960 to test the Beaupre multi-stage parachute system. The final test set a...
