Since finding all the planets in our Solar System, the search was on for planets around other stars (extrasolar planets). As methods and technology improve, more extrasolar planets are found ...
A satellite is anything that orbits around another object. Moons are natural satellites that orbit around planets, whereas artificial satellites are objects that people have made and launched ...
In November 2014, the European Space Agency (ESA) Rosetta Mission landed a space probe called Philae onto the surface of Comet 67P, while Rosetta continued to orbit the comet. The touchdown was ...
In this activity, students use a scale model of the Earth and identify altitudes of various satellites. They then use a smaller object on a string to model gravity and satellite motion. By the ...
In this activity, students consider evidence for life on other planets outside our Solar System. They examine data to decide on the likelihood of life on certain extrasolar planets. By the end of ...
In this activity, students use different pieces of a jigsaw to work through a process of observation, discussion, collaboration and deduction to determine what the picture shows. The activity is ...
Search data from NASA’s Kepler spacecraft for the dips in star light intensity caused by exoplanets – planets that orbit stars other than the Sun. As these exoplanets pass between the star and ...
Globe at Night is an international citizen science campaign to raise public awareness of the impact of light pollution by inviting citizen scientists to measure and submit their night sky ...
Loss of the Night is an international citizen science project aiming to quantify the illumination of the night sky caused by artificial light. By monitoring how bright the night sky is over time ...
Why is the sky blue? Why do stars twinkle? Why did the apple fall to the ground? What happens if I hit this rock with another rock? As humans, we’re curious, and throughout history, we’ve ...
In this online PD session recorded on 13 August 2015, secondary school teacher Steve Chrystall describes how he uses the Science Learning Hub’s satellites and rocket resources to teach space and ...
Are you looking for ways to teach forces? If you’re new to the Science Learning Hub, you may want to start with our introductory video on teaching physics. Alternatively, use the links below to ...
Professor Denis Sullivan, from Victoria University of Wellington, explains why we can only detect extrasolar planets indirectly. He outlines the ‘wobble’ method of detecting planets around ...
The Rosetta spacecraft needed to be able to survive the rigours of launch and extreme temperatures from -200C to 300C. Avionics engineer Warwick Holmes talks about his role in building and ...
When Rosetta finally caught up with and went into orbit around Comet 67P, an intensive imaging campaign began. Rosetta Mission engineer Warwick Holmes explains some of the powerful imaging ...
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 ...
Astronomers use telescopes that detect radiation from different parts of the electromagnetic spectrum. This interactive explains which part of the spectrum various telescopes are able to view and ...
This timeline lets you see aspects of Frank's life and work, and how these fit into a wider science picture of earthquake forecasting. A full transcript is underneath.
