The Hubble Space Telescope orbits outside the distorting influence of Earth´s atmosphere.
The Kepler space telescope was launched by NASA to discover Earth-like planets orbiting other stars
Observatories are often built at high elevations to minimise the effects of atmospheric turbulence
The diameter of our galaxy is about 100,000 light years; it contains more than 100 billion stars, one of which is our Sun.
Galileo Galilei's scientific achievements contributed greatly to the advancement of physics and astronomy.
The three important laws describing planetary motion were formulated by Johannes Kepler.
In 1946 a Hungarian scientist was the first person to detect radar echoes from the Moon.
A wide variety of optical instruments are in use today, ranging from microscopes to telescopes.
This animation introduces the studies of astronomers and physicists whose works fundamentally changed our view of the universe.
James Cook's legendary journey around the world proved to be enormously valuable for science.
The eye is one of our most important sense organs. When stimulated by light, electric impulses are produced by its receptors.
The curvature of the lens of the eye changes when we look at a distant or at a near object, to ensure a sharp image.
This animation demonstrates the process of star development for average and massive stars.
Concave and convex lenses are used for the correction of short-sightedness and far-sightedness.
The Voyager space probes were the first man-made objects to leave the Solar System. They gather data about outer space and carry information about humanity.
This animation demonstrates the structure and operation of digital cameras.
