Dr Allan McInnes and Dr Adrian McDonald, from the University of Canterbury, explain how gravity and projectile motion keep natural and artificial satellites in an orbital path.
NIWA scientist Dr Katja Riedel travels to Antarctica to collect 300-year-old ice samples. She studies the ice to learn how our atmosphere has changed over the centuries.
Scientists observe water in its different forms to develop explanations of how the world works.
The size, orbit and design of a satellite depend on its purpose. In this interactive, scientists discuss the functions of various satellites and orbits. Accompanying fact files provide ...
This animation explores water as a solid, liquid and gas. The water molecules stay the same, but they behave differently as they change from one form to another.
Most urban drinking water is cleaned and treated in an ordered series of steps.
