The Sun or Sol, is the star at the centre of our solar system and is the largest object - about 109 times the diameter of Earth. It contains more than 99.8% of the total mass of the Solar System. Through this collection you can explore and observe the behaviour and characteristics of the Sun.
Stars are cosmic energy engines that produce heat, light, ultraviolet rays, x-rays, and other forms of radiation. They are composed largely of gas and plasma, a superheated state of matter composed of subatomic particles. Discover various types of stars through this collection.
Science keeps unraveling mysteries of the Universe every day while our imagination plays a big part of the process. From designing aliens to glittering milky way, the collection touches both creativity and knowledge to explore the Universe with hands on activities from low cost materials.
A galaxy is a massive, gravitationally bound system consisting of stars, stellar remnants, an interstellar medium of gas and dust, and dark matter. Roughly one hundred billion galaxies are scattered throughout our observable Universe, each a glorious system that might contain billions of stars.
The Moon is the Earth’s only natural satellite and the fifth largest moon in the Solar System. It was formed 4.6 billion years ago. The Moon is in synchronous rotation with Earth meaning the same side is always facing the Earth. Observe and explore Earth's companion through the collection.
