Protective shield :Magnetic field of Earth

  Our planet's magnetic flux is believed to be generated at its heart, within the Earth's core. Nobody has ever journeyed to the centre of the world, but by studying shockwaves from earthquakes, physicists are ready to compute its likely structure. In the guts of the world may be a solid inner core, two thirds of the dimensions of the moon, made mainly of iron. At 5,700 °C, this iron is as hot as the sun's surface, but the crushing pressure caused by gravity prevents it from becoming liquid. Surrounding this is often the outer core, which consists of a 1,242 mile (2,000 km) thick layer of iron, nickel, and small quantities of other metals. Due to the lower pressure than the inner core, the metal here is fluid. Differences in temperature, pressure, and composition within the outer core cause convection currents within the molten metal as cool, dense matter sinks and warm matter rises. The "Coriolis" force, formed by the Earth's spin, causes swirling whirlpools

Blue coloured Unusual Planet Uranus

Image
Uranus     is the seventh planet from the Sun. The first planet found with the help of a telescope, Uranus, was discovered in 1781 by an astronomer named William Herschel, although he originally thought it was either a comet or a star. But, after two years, it was universally accepted as a planet. Uranus is four times than that of the Earth.   The planet's name is derived from The planet was named for Uranus, the Greek god of the sky, as suggested by the astronomer Johann Bode. Johann Bode was the astronomer who observed this planet after William Herschel. According to Greek mythology, the name is a reference to the Greek god of the sky,  Uranus , who was the grandfather of Zeus (Jupiter) and the father of Cronus (Saturn).   Uranus' Atmosphere- It is the third-largest planet in the Solar System. Uranus is the cold planet in the solar system. It is very cold and windy. The planet's mass is made up of a hot, dense fluid of "icy" materials, i.e., water, methane, and

Understanding what Color Says

Image
  Color psychology suggests that different shades of colors could have a wide range of effects, from boosting your moods to causing anxiety. But can the colour of the products you purchase say something about your personality trait ? For example, could the color of the car you bought somehow relate to some underlying personality traits or quirks? Your colour preferences when buying items might say something about the type of image you may be trying to project.  Color preferences, from the clothes you wear to the car you drive, can sometimes make a statement about how we want other people to perceive us.  Other factors, like age, and gender also have an influence in your  choice of color you make. White : As many of our readers have suggested, the colour white can feel fresh and clean. The colour is often used to evoke a sense of youth and modernity.  Black : Our readers often describe black as a "powerful" color, which might be the reason why black is the most popular c

Return of Apophis: Will it Crash on Earth

Image
  Scientists prepare for their last good look at asteroid Apophis before its 2029 flyby. Astronomers first spotted the space rock, now known as Apophis, in 2004. It passed by in the year 2021, and once again will be uncomfortably close to Earth on April 13, 2029. Apophis will skim so close to the Earth that it will pass through the realm of high-altitude satellites. Researchers say it will not hit the Earth. The observations gathered in 2021 help them calculate its next approach when it will pass close to Earth. But scientists are positive that it will not hit Earth. The basis for their saying is the study that they conducted when Apophis passed by the Earth. Scientists use it as a powerful tool for studying asteroids from Earth and processing the data. They study pointing a powerful radar beam at an object while using a sensitive radio telescope to catch the echo bounced back. Scientists' priority while preparing for the 2029 Apophis flyby is to sharpen their view of th

Earthquake - You Must know before Its too late

Image
A team of scientists at NASA's Jet Propulsion Laboratory, in Pasadena, California, has developed a new imaging technology that could lead to the prediction of earthquakes. The new airborne radar-based mapping technology allows scientists to see earthquake images on the ground for the first time. An earthquake is an extended release of energy, though the energy is released not only when the event occurs, but also in several stages before the earthquake. You can see and sense the appearance of abnormalities (thermal ions) in the atmosphere near the location and time of the earthquake. These abnormalities are detected only by the satellites. The prediction can be further distinguished from earth warning systems that, upon detection of an earthquake, provide a real-time warning of seconds to neighbouring regions that might be affected.   Scientific Methods of Prediction of an Earthquake:   Before the earthquake, there was a foreshock or minor shock. You will know about the com

Apophis, the Space rock

Image
The Space rock, which was spotted by Astrologers in the year 2004 . Scientist gave the name  Apophis to the name of the god of chaos in ancient Egyptian mythology. This space rock is 300 meters wide and its height is around the height of Eiffel Tower. Roughly ,  t hat’s  about the size of three-,and-a-half football fields. This Asteroid consist of rock and metal and the shape is that of a peanut. Apophis has a complicated spin state; it’s sort of spinning ,and tumbling at the same time. Recently, on March 5,2021 Apophis flew closely to Earth . The next approach of Apophis a bit scary. In the year 2029, 13 April, Apophis will re-visit Earth with extreme nearness and uncomfortable closeness. Many consider it as a ‘Doom day’  they say the closeness to Earth will be pulled by Gravitational Force of Earth.   Scientists deny the fact of its strike on Earth. Some Astrologers as well as Elon Musk say, ‘it will slam into the Earth that day’. Their verdicts are on the extreme closeness and the

8th Continent New Zealandia

Image
  In 2017, a group of geologists announced the discovery of New Zealandia (Te Riua Mui among the Maori), a vast landmass of 4.9 million square kilometers, about six times the size of Madagascar. The catch is that 94% of its miles are underwater, with only a handful of islands, which include New Zealand, thrusting out from its oceanic depths. It has been hiding in undeniable sight all along. Four years on, and the continent is as enigmatic as ever, its secrets and techniques jealously guarded under 6,560 ft (2 km) of water. How did it take shape? What used to stay there? And how lengthy has it been underwater? Studying the geology, it's concluded that New Zealand is "the remnant of a mountain-chain that shaped the crest of an exquisite continental location that stretched a long way to the south and east, and that's now submerged." Till recently, the oldest crust and rock ever sampled from Zealandia used to be simply five hundred million years old, whereas all the di

Inner core of the Earth has been growing faster under Indonesia's Banda Sea and Brazil

Image
    Consistent with a replacement study, the solid-iron inner core of the world has been growing faster on one side than the opposite for over 500 million years. It is growing faster under Indonesia's Banda Sea than under Brazil, but this uneven growth pattern hasn't left the core lopsided, say seismologists at the University of California, Berkeley, who are investigating the phenomenon. Gravity has acted to evenly distribute the new growth, made from iron crystals that form as molten iron begins to chill, maintaining a spherical inner core density.   Even though it doesn't leave the core lopsided, this uneven rate of growth suggests something within the outer core under Indonesia is removing heat from the inner core at a faster rate than it's under Brazil on the other side of the earth, the team said. Researchers say this discovery has helped them "prove rather loose bounds" for the age of the inner core, which is between half a billion and 1.5 billion y

Reason behind Ice Sheets is melting

We have two major Ice mass in our planet Artic region, in the North and Antarctic Peninsula, in the south. Antarctica is a landmass which is no man’s land and no government occupies the extended piece of land. It had been the base for the scientists and researchers of many countries. Antarctica is covered with Ice sheets throughout centuries. It had also been the place for study of the weather conditions of different phases of million years age. the Land had been the witness of extreme climates faced by the Earth in past billions of years. The major worry of the scientist’s community is the global warming. If the Global warming is not taken into consideration to alter the situation, then the humanity will suffer it consequence.   Detached Ice masses In Antarctica Recently, the researchers are been alarmed of the sign of  Antarctica getting warmer. When mapped in the reading radar from the satellite, - the heat zone was found beyond normal spread over Antarctica. It concerned th
