Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. …
The Moon is a natural satellite of Earth and orbits around it at a distance of 248,308 miles/ 399,614 kilometers from Earth. It takes 27 days to orbit around Earth. The Moon has been highly regarded in mythology and symbolism that are deeply rooted in many spiritual beliefs around the world. Its reverence comes from …
How are the Northern Lights Formed? The Northern Lights are created when the wind from the Sun hits the Earth’s magnetic field. Solar wind carrying energetically charged particles, from explosive flares and coronal mass ejections on the Sun, can trigger magnetic storms on Earth called substorms. These substorms cause Earth’s oxygen and nitrogen particles to …
Mercury retrograde is a phenomenon that occurs several times a year when the planet Mercury appears to be going backward in its orbit.
The sun’s solar wind is made of charged particles that interact with the Earth’s magnetic field. Eventually, particles collide with atoms and molecules in Earth’s atmosphere and create an interaction that provides the atoms with extra energy which is released as a burst of light.
