Our universe is full of mysterious objects and amazing phenomena. All the objects of universe rotate in one or other way. For example planets spin on their axis and revolve around the sun. The sun also spins and revolves around the center of the galaxy. Even the galaxy itself rotates. Have you ever thought why do these bodies rotate? Continue reading “Why do planets spin?”

Origin of Elements in the Universe: An Evolution after Big Bang Explosion

The planet Earth contains various types of elements which form soil, rocks, air, vegetation, species etc. There are nearly 118 elements in the nature. Every element has its specific properties. You will be surprised to know that these elements were not formed at the time of Big Bang Explosion. After the Big Bang only lighter elements like Hydrogen and Helium were formed. Then how the rest of the element originated? How did the materials for formation of planets and asteroids get formed? Continue reading “Origin of Elements in the Universe: An Evolution after Big Bang Explosion”

What is Dark Matter? In Simple Terms Here

Human are always curious to understand the nature and its phenomenon. When we look towards the space, we find that the space contains large number of massive objects like asteroids, planets, stars, clusters, galaxies. The size of any galaxy is enormously large that we can’t imagine. Even our sun is very large although it is an average star. But you will be surprised to know that all these objects like stars and galaxies taken together make just 5 % of total content of the universe. Are you curious to know where the remaining part of the Continue reading “What is Dark Matter? In Simple Terms Here”

Hypothetical Planet Vulcan orbiting between Mercury and Sun

The planet Mercury is closest to the Sun in the present model of the solar-system. The planet Vulcan was the proposed planet which was assumed to be orbiting around the Sun in the region between Mercury and Sun. Proposal of planet Vulcan was based on the calculations of Le Verrier which was done to explain the peculiarities in the orbit of Mercury. Le Verrier was the same French mathematician who predicted the existence of the planet Neptune by calculations to explain the orbit of Uranus. Le Verrier Continue reading “Hypothetical Planet Vulcan orbiting between Mercury and Sun”

Sky is full of beautiful objects which always attract human and give rise to curiosities. In your childhood, you must have been wondering what are these twinkling objects and what are they made up of? You must have heard or read that the researchers have discovered Hydrogen and Helium in Sun. So what do you think how do they know that? Have they gone to the Sun and brought the sample and then studied them to know about the composition of Sun? The answer is no because no one can go to the Sun and collect the samples. So how do they detect the composition of Sun or any other star? Continue reading “Spectroscopy Technique for determination of composition of Sun”

Near Earth asteroid held together by weak cohesive force

A Near-Earth asteroid having a potential threat to Earth does not have enough gravity to hold it together with its very high spinning speed. The spinning speed is high enough to break it apart into pieces then how is this asteroid held together? Continue reading “Near Earth asteroid held together by weak cohesive force”

What will happen during Collision of Milky Way with Andromeda Galaxy?

You must have heard about the collision of an asteroid with the planet and aware of the destruction that can be caused by such an event. But there is one bigger cosmic event that is the collision of our Milky Way Galaxy with the Andromeda Galaxy. These two galaxies will merge to form a new galaxy in future. This was the common process of formation of new galaxies after the big bang. Continue reading “What will happen during Collision of Milky Way with Andromeda Galaxy?”

NASA’s researchers have performed an experiment and demonstrated the possibility of fuel- less space drive which could be propelled just by the momentum transfer via the quantum vacuum virtual plasma. The thrust for the space drive will be provided by the oscillating waves in Radio Frequency (RF) Resonant Cavity. The possibility of this fuel-less space drive could change the future of space technology, where distances could be travelled much faster and solar sail will not be just a fictitious dream. Continue reading “NASA confirms possibility of Fuel-less RF space drive”

There are lot space flight and mission till today. Many space probes are wondering in the space in the search of different scientific discoveries but then one important question arises in mind “ Which is the farthest space probe till today?”

The answer lies in the very far lying machine which is travelling at a tremendous speed of human history away from us called Voyager 1. Continue reading “Voyager 1: The Farthest Milestone of Human History”

Mystery of the Ears of Saturn

Saturn is the second largest planet of our solar system but this fact does not make it unique and attractive. The most beautiful and amazing thing related to Saturn is its wonderful ring system which surrounds the planet making it the most mysterious planet of our solar system. This ring system is composed of many ringlets and gaps and it is inclined to the orbital plane of Saturn by 27 degrees. The theory behind this amazing ring system is not complete till today there are lots of mysteries behind them and their origin. Continue reading “Mystery of the Ears of Saturn”
