Neptune is denser than Saturn because of its composition. While both are made primarily of hydrogen and helium, the particles of these elements are packed together far more tightly on Neptune, giving the planet a greater density. In addition, Neptune’s environment has far more icy features that add to its mass and density. Continue reading … Read more
The Hubble Telescope is a general-purpose observatory created by NASA to make accurate and clear observations of space in visible, ultraviolet, and infrared wavelengths. The Kepler Telescope was a mission commissioned by NASA to search for exoplanets in their stars’ habitable zones. Discover more about the Hubble and Kepler telescopes; learn how each one works, … Read more
Cosmic rays are high-energy particles that originate from outside of Earth’s atmosphere. Many consist of a single proton and interact with our atmosphere to become air showers. Gamma rays are the radiation from the shortest wavelength on the magnetic spectrum, which can originate both on and outside Earth. Discover where cosmic rays originate and how … Read more
The main differences between Neptune and Charon is that Neptune is a gas based ice giant whilst Charon is Pluto’s largest moon, Neptune has 14 moons surrounding it whilst Charon has 0 and Neptune has the fastest winds in our solar system at 2,000 km/h whilst Charon’s extremely thin atmosphere means wind is practically non-existent … Read more
The main differences between the Moon and Io is that the Moon is Earth’s only moon whilst Io is a Galilean moon and 1 out of 79 moons that orbit Jupiter, The moon is the 5th largest natural satellite in our solar system with a diameter of 3,474.8km whilst Io is 4th with a diameter … Read more
The main differences between Uranus and Charon is that Uranus is an ice based gas giant and the 3rd largest planet in the solar system with a diameter of 50,724km whereas Charon is Pluto’s largest moon with a diameter of 1,212km, Uranus has 27 moon whilst Charon has 0 and Charon is a low density … Read more
Pluto has a surface area of 17.6 million km² with an estimated volume of 6.4 billion cubic kilometers whilst Australia has a surface area of 7.6 million km² with an estimated volume of around 304 million cubic kilometers making Pluto more than twice its surface area and 20 times its volume. For a breakdown of the size of … Read more
If you’re in the market for a telescope, the number of available options certainly do not make it easy on your average to find. Whether you want one best suited for astrophotography, the best price to aperture ratio devices or simply the most versatile devices, you’re likely have a hard time deciding what to go … Read more
There is a balance between the gravitational force of the Sun and the planets, which causes them to orbit. The planets are not just going around in circles. They are moving in ellipses, which means they move closer to and farther away from the Sun as they orbit. Continue reading to discover how the planets … Read more
Whether or not the Moon is “falling” towards Earth depends on your definition of the word falling. The Earth does draw the Moon closer with its gravity; at the same time, this momentum creates an orbital speed that allows the Moon to travel around the Earth in line with its natural curvature. Discover why the … Read more
