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”

Spectroscopy Technique for determination of composition of 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 confirms possibility of Fuel-less RF space drive

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.
