In astrophotography, colours are treated in different ways – telescopes generally do not take colour pictures, but use special filters to capture light in particular parts of the optical spectrum (e.g. red light only). This interactive app from the Faulkes Telescope project will show you how colour images are made using different filters, combining them to make various types of “colour image”.
Gain access to the Faulkes Telescope project, where teachers and students can access a global network of telescopes. Both live- and queue-based observations are available.
Choose what you want to observe and get your own pictures of planets, galaxies and nebulae.
Access to the Faulkes Telescope project is available for teachers and students in Denmark, Finland, Norway and Latvia through Online Observatory – do not miss out on this opportunity!
The rotation of the Earth is investigated by observing the length
of a toy figure’s shadow in the course of a day. As an
introduction, the pupils can spin around themselves like the
planet Earth to reveal the daily motion of our planet, and they
can try to create different kinds of shadows with a torch.
As an extended task, you can use the free Stellarium software to
investigate how the Sun seems to move across the sky in the
course of a day and how this movement changes in the course of
