Apart from its captivating appearance, the hybrid eclipse...
The asthenosphere is a layer of the upper mantle of Earth located below the lithosphere. Despite the great difficulty in accessing the various layers of the Earth, the geographical sciences have allowed us insight into the different layers which make up the Earth. The three main parts are the Earth's crust,...
The different types of solar and lunar eclipses are total solar eclipse, partial solar eclipse, annular solar eclipse, total lunar eclipse, partial lunar eclipse and hybrid eclipses.

The troposphere is the lowest layer of Earth's atmosphere and is also the most important layer of the atmosphere for life on Earth. It contains the air we breathe and the water vapor that forms clouds and precipitation. The troposphere also plays a vital role in regulating the planet's climate. However,...
The different layers of the sun are the core, radiative zone, convective zone, photosphere, chromosphere and corona. Each of them has a specific function and certain characteristics that distinguish them. The sun is the largest and closest star to our planet, located 93 million miles (150 million km) from...
The different galaxy types include spiral galaxies, elliptical galaxies, irregular galaxies, dwarf galaxies, lenticular galaxies and interacting galaxies. Galaxies are enormous collections of gas, dust, stars and dark matter. They are joined together thanks to gravity, collectively forming parts of the known...
It is no secret that the Perseid meteor shower, also referred to as the tears of Saint Lawrence, is one of the most popular events in August.

Although our Moon itself never changes shape, the amount visible to us on Earth is variable. When the side of the Moon facing our planet Earth is fully illuminated...
The Earth, our home in the vastness of the universe, is a dynamic and vibrant planet in constant motion. The Earth's movements play a fundamental role in our daily lives and the grand tapestry of nature. From its rhythmic rotation on its axis that makes day and night possible, to its graceful dance around...
The moon has held a significant place in the hearts and minds of people throughout history. As the brightest object in our night sky, it has guided travelers and sailors for ages. Its changing phases have been celebrated across cultures, inspiring myths and legends of lunar deities and transformation....
Uranus is the seventh planet in the solar system and it has 27 moons. When we compare this to Earth's paltry one moon, it may seem like a lot. However, this doesn't mean Uranus is the planet with the most moons. This honor belongs to Saturn which has at least 124 traditional moons. Moons are natural satellites...
Although we may associate rings most with the planet Saturn, Neptune has five rings called Galle, Le Verrier, Lassell, Arago and Adams. Characterized by its intense blue color and its winds that are stronger than hurricanes, Neptune is the planet in our solar system furthest from the Sun. Study of this planet...
Throughout the history of human exploration, our fascination with celestial bodies has driven us to uncover the secrets of the cosmos. Mars, often referred to as the "Red Planet," has held a special place in our collective imagination. In addition to its reddish hue and its potential as a future human...
The mesosphere, which lies between the stratosphere and the thermosphere, is an important layer of the Earth's atmosphere. Although the mesosphere is less talked about compared to other atmospheric layers, it plays a critical role in protecting life on Earth by shielding the planet from meteorites. In addition,...
Water is one of the most important substances for life on Earth and covers a large part of the planet's surface. Earth is often called the "blue planet" because of its abundance of water. Earth's total water supply is estimated to be about 1.4 billion cubic kilometers (332.5 million cubic miles). This includes...
We may be aware there are 6 continents into which the Earth's land mass is divided. These are America, Africa, Europe, Asia, Oceania and Antarctica. Although this conformation of land appears to have always been this way, our planet has looked very different across the billions of years of its existence. Different...
Climate refers to the long-term weather patterns of a particular region or area.
