There are many theories regarding why there is lava on the Earth. Scientists believe it is formed from melted rock deep inside the Earth and then rises to the surface. One theory says that magma (molten rock) rises to the top of a volcano when gasses dissolved in it expand […]

The temperature on Earth without Sun
The Sun is a huge gas, or plasma, that produces heat and light by nuclear fusion. The Sun’s energy also fuels the Earth’s weather and climate through solar radiation. The Earth’s average surface temperature is about 15 degrees Celsius (59 F or 288 K). As the planet goes in and […]

Artificial Satellite of Earth
A robotic satellite is an object which has been placed into orbit. Such things are sometimes known as “artificial satellites” to differentiate them from natural satellites such as the Moon. Satellites are used for many different purposes, from communication to Earth observation. The Sun can be a powerful energy source, […]

The Complete History of the Earth and Life
The Earth’s history is a broad subject and can be treated from many perspectives. The age of the Earth is about 4.54 billion years (with an uncertainty of about ±20 million), making it one of the oldest objects in the universe. During the Eoarchean Era, the first clue of life […]

How Many Layers of Atmosphere on Earth?
The earth’s atmosphere is the layer of gasses, commonly known as air, that surrounds the Earth and is possessed by gravity of earth. The climate on Earth is life-supporting by penetrating UV solar radiation, warming the surface through heat absorption (greenhouse effect), and reducing temperature rise during day and night. […]

Transiting Exoplanet Survey Satellite (Tess) Mission
What Is Tess? The Transiting Exoplanet Survey Satellite is the subsequent stage in the quest for planets outside our planetary group, including those that could uphold life. TESS will review 200,000 of the most brilliant stars close to the sun to look for traveling exoplanets. On April 18, 2018, TESS […]

The Black Hole in Space
The black hole is a location in the Universe where gravitational power is so strong that even light cannot get out. The gravity is solid since the issue has been fit into a tiny area. As there is no light around or inside a black hole, It’s not visible to […]

Speed of Light in Air
The speed of light is how light waves engender through various materials. Specifically, the incentive for the speed of light in a vacuum is presently characterized as precisely 299,793,459 meters each second. The speed of light is viewed as a principal steady state of nature. Its importance is far more […]

What Is Betelgeuse Supernova
Betelgeuse usually is the 10th most splendid star in the night sky and, after Rigel, the second-most brilliant in the heavenly body of Orion. It is a particularly rosy semiregular variable star whose evident extent, changing somewhere in the range of +0.0 and +1.6, has the most extensive reach shown […]
