Discover what exist in the universe
The exoplanet discovery race is on. Since 1995, when the first exoplanets were found orbiting a pulsar (a fast-spinning neutron star), astronomers have discovered more than 2,000 planets around other stars. The most striking thing about this large sample of alien worlds is their diversity: these planets are unlike anything […]
Global warming is the observed long-run, up to century, rise in the average temperature of Earth’s climate system and its related effects. Collective of scientific evidences show that the climate system is warming. With global warming and climate change becoming a real issue, it’s important to know how to help […]
Our planet has seen a rise in global temperatures in the last century. Not only is this impacting the weather patterns that we experience, but it is affecting how quickly ice caps melt and how much rainfall gets delivered to certain geographical areas. Climate change effects are being observed in […]
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 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 […]
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 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 […]
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. […]
The exoplanet is a planet outside the solar system. An exoplanet is any planet past our planetary group. Many revolve around stars, yet free-drifting exoplanets, called maverick planets, circle the galactic focus and are unleashed to any star. The majority of the exoplanets found are in a by and prominent […]
Mars is the fourth planet from the Sun and is often referred to as the Red Planet due to its reddish appearance. The planet Mars was named after the Roman god of war and has been a popular subject for science fiction writers, artists, and filmmakers over the years. Before […]
