The meteorite has gained its fame from one of the world’s best-loved superheroes, Superman. The Man of Steel’s Achilles’ heel is the mineral kryptonite – and the villains in his life have probably thanked all the meteorites that encapsulated the small substance.
In general, convection is another mechanism by which heat can be transferred. In the same manner, the Sun uses this method to transfer the energy it produces from the core towards the outermost region. This process takes place in the region of the Sun called the convection zone. From the core, the energy is transferred

Venus, the second planet away from the sun, completes one revolution in about 225 earth days. It is a very bright heavenly body, which has a peak apparent magnitude of -4.6. This brightness is enough to cast shadows on earth. Because it shines most brightly right before the sun rises and right after the sun
Solar winds stream off from the Sun in all directions on average speeds of about 400 km/s which is the equivalent of approximately 1 million miles per hour. The source of these is the Sun’s very hot corona. There are two major reasons why these solar winds can escape the Sun’s gravity. First are the

The Sun and the Moon are two of the most observed celestial bodies. These celestial bodies that are seen at day and night time are often the basis for determining time. The Moon has been observed over time and its phases and eclipses have been the source of many superstitions and time calculations. A lunar
People from all walks of life may not agree on most things. But it is assumed that they do agree on the beauty of the sky, especially on a clear night. When you chance upon a meteor shower, you look up in awe in its beauty. But when you come upon a meteor storm, you
Tremendous amounts of heat and light energy are released by the Sun. The energy of the Sun or solar energy has immense effects on Earth’s life. Solar energy is changed to chemical energy during photosynthesis in green plants. The Sun emits light energy which is important in the food making process. Plants trap energy from

Gravity is a natural occurrence in which physical objects are attracted toward one another. This attraction is proportional to the objects’ masses. Since the mass of each planet is different, the gravitational pull on an object will be different on each planet as well. Hence, an individual’s weight would vary depending on what planet they
