The Antarctic ice sheet is one of the two polar ice caps of the Earth. It covers about 98% of the Antarctic continent. Antarctica is considered as a desert as this place is the coldest, driest, and windiest on the earth. It has the highest average elevation of all the continents. Now, NASA ice scientists have found a shrimp-like creature and a possible jellyfish 'frolicking' beneath 600 feet of solid Antarctic ice, where only microbes were expected to live. Continue reading →
The human brain is the center of the human nervous system and is a highly complex organ. According to BBC, A detailed, functional artificial human brain can be built within the next 10 years, a leading scientist has claimed. The team are trying to reverse engineer the brain. Continue reading →
Short answer - No, Pluto is no longer a Planet. It is a dwarf Planet.
It was originally classified as a planet, Pluto is now considered the largest member of a distinct population called the Kuiper belt. Pluto, considered a planet for 76 years, was reclassified as a dwarf planet in 2006.
What is a dwarf planet?
Pluto was found by Clyde W. Tombaugh in 1930. A dwarf planet, is a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite. More explicitly, it has to have sufficient mass to overcome rigid body forces and achieve hydrostatic equilibrium.
What is a planet?
A planet is a large object such as Earth that orbits a star. It is smaller than a star, and it does not make light. Planets are ball-shaped (or spheres). Objects that orbit planets are called moons. Pluto used to be known as a planet, but in August 2006, a group of astronomers decided it should be called a dwarf planet instead. there are three main conditions for an object to be considered a 'planet':
The object must be in orbit around the Sun.
The object must be massive enough to be a sphere by its own gravitational force. More specifically, its own gravity should pull it into a shape of hydrostatic equilibrium.
It must have cleared the neighbourhood around its orbit.
Pluto meet the first two conditions, but failed to meet the third condition, hence it is not a Planet. You can learn more about Pluto here at the wikipedia.
A credit crunch (credit crisis) is a reduction in the general availability of loans (credit) or a sudden tightening of the conditions required to obtain a loan from the banks. A credit crunch generally involves a reduction in the availability of credit independent of a rise in official interest rates. The following video explains credit crisis in simple terms with the help animation. The goal of giving form to a complex situation like the credit crisis is to quickly supply the essence of the situation to those unfamiliar and uninitiated.
