Planet Venus is the second planet from the Sun. It is named after the Roman Goddess of love and beauty. Situated just before Earth in the solar system, it does not have any moons. The reason behind the absence of moons could be the placement of the planet so close to sun. All the [...]
This has always been a tricky question for the researchers and scientists. There are many approaches to calculate the scientific age of the earth. Some researchers believe the Earth is about 6,000 years old while others believe that it is as old as 4.56 billion years. The age of the oldest rocks on the Earth [...]
The oldest rocks found on earth until 2008 are known to be 4.03 billion years old. These rocks were found in Canada’s Northwest Territories called Acasta Gneiss. Originally, this rock was found as a part of an old mountain chain. Its core was exposed due to glacial activities over billions of years. This oldest rock [...]
About 1.2 trillion barrels is the amount of oil in the world today. The amount looks too huge but humans consume a huge amount. Besides, the supply of oil is decreasing. The demand outstrips the supply. Some believe that 1.2 trillion barrels would run out in 44 years if the present usage reports were [...]
The sun generates nearly 386 billion million gigawatts, most of which is electromagnetic radiation. In comparison, a nuclear reactor makes only one gigawat of energy. Only a fraction of this radiant energy reaches the Earth and is responsible for all life.
The Sun produces heat and light through an unceasing series of nuclear reactions. This process [...]
Vitamins are broadly categorized into two classes that include water-soluble and fat-soluble. This classification is based upon their solubility and is further split into sub- categories. Vitamins are compounds, which enable in bringing about improved body functions and metabolisms.
Fat Soluble Vitamins
The fat- soluble vitamins include vitamins A, K, D, and E. These vitamins are soluble [...]
The number of plant species is discovered with increased efficiency every year. Currently, the number stays at about 375,000 with the seeded plants, ferns, fern allies and bryophytes. Of these, 258,650 plants belong to the flowering category while the rest are a part of the bryophytes (16000), which include mosses, hornworts and liverworts. There are [...]
Fungi are unicellular and multi-cellular organisms belonging to the genus heterotrophic phylum. More than 100,000 organism species are classified as fungi. Fungi are categorized into four prominent types: Zygomycota, Basidiomycota, Deuteromycota and Ascomycota.
Zygomycota fungi are mostly molds that feed on dead plants and animals. These parasites flourish on insects and plants. The method of [...]
Bacteria are single-celled organisms found in all environmental conditions. They are classified based on their shapes, sizes, cell structure, cell components, and metabolism. Scientifically, bacteria are classified into various phyla. Phyla are the scientific classifications of organisms.
Classification based on shapes
Before the DNA techniques were used for classification, the bacteria were classified on their shapes. The [...]
The satellites in the space are tracked down by the Space Surveillance Network of United States. It has tracked approximate number of currently 3,000 satellites in the orbit around the Earth. These satellites are the ones which are in proper working condition and in the correct locations on the orbits.
Satellites from countries
Satellites have a lifespan [...]
Proteins are the basic building blocks of our bodies. It is estimated that the human body comprises of approximately two million proteins, which are coded by only 20,000 to 25,000 genes. There are groups of 20 amino acids that form the molecular chains of protein. However, the number of proteins found in a biological organism [...]
Many people wonder about the total number of elements present in the Earth’s crust. The right answer to this question is around 118 elements according to the periodic table. There are about 94 elements that are naturally occurring while the remaining are said to be the trans-uranic elements or artificial elements, which are synthesized in [...]
Ultra Violet light or UV rays is an electromagnetic radiation naturally emitted by the sun. It is also radiated by specially created light like the black light. The UV wave length is shorter than the visible light. A UV wavelength determines how long the wavelength of a particular light is. It is measured in nano [...]
Weather is dependent on a number of factors like humidity, atmospheric pressure, ambient temperatures, rains, wind speed and direction and more. Different instruments are used to measure each of these parameters. The meteorological department of each country collects this information to forecast the weather.
Anemometer
Anemometer is used to measure the direction of the wind, hygrometer is [...]
Depth of the sea is measured by two basic methods: by using the acoustic echo sounders on the ships and by using data from the satellite altimeters. As the name suggests, the echo sounders measures the depth of the sea by using echo of sound as measure. The instrument transmits a 10-30 kHz sound and [...]
Temperature is an indication of the measure of how hot or cold a particular substance is. Temperature is a physical property of a substance. It can be measured using a thermometer. A conventional thermometer contains mercury in a thin vial and is marked with a scale which helps a person read the temperature of a [...]
According to the recently conducted studies, it has been estimated that the universe will not end for an extremely long time. It is believed that the universe is still expanding because of the initial forces of the big bang theory. However, the actual answer to this question really relies on the availability of the physical [...]
The real beauty of the country India lies in its flora and fauna, its flowing rivers and yes, how can we not mention, the mighty Himalayas. The Himalayas are one of the most beautiful mountain ranges of the world. Often do we wonder what had been the story behinds their evolution. It must surely have [...]
The geological time scale’s development dates back to 1815. The connection between the fossils and the rock was estimated by a builder, William Smith. He noticed that the fossils were not only some kind of material and minerals, but had some connection with the rocks. This triggered the beginning of the development of the Geological [...]
The earth is the only known planet having life. It is the third largest planet in the solar system. In comparison to others, our planet is the most comfortable one with abundant water, a magnetic field that protects from the heat and rays of the sun. The earth’s origin was created from the solar nebula. [...]
