The Guide to Space

Image
We all have already leaned about our solar system, Meteoroids & Meteorites, Asteroids & Comets in our school. now we are learning about some more interesting things in the space   Quick revision           Our solar system is the one we know the most about. The Sun is at its center. Our solar system includes everything that orbits or goes around the Sun. Planets, moons, asteroids; comets and dust are all part of the solar system. Our solar system lies near the edge of the Milky Way galaxy. The Milky Way is shaped like a whirlpool. All the stars in the galaxy, including our Sun, orbit around the center of the Milky Way. With the discovery of Pluto in 1930, astronomers considered the Solar System to have nine planets. Pluto was classified as the ninth planet and it remained so for 75 years but in 2006, International Astronomical Union classified Pluto as a ‘dwarf planet’ due to its smaller mass. In view of this, our solar s...

the Awesomeness of Neutron Stars

                                       Twinkle, twinkle, little star,  How I wonder what you are.                            Up above the world so high,  Like a diamond in the sky         Undoubtedly we all love stars but ever wondered about  what types of stars would their be, how they are formed, tod ay we are talking about one of the most awesome things in space Neutron Stars :  the Awesomeness & Facts              they are actually   a celestial object of very small radius (typically 30 km) and very high density, composed predominantly of closely packed neutrons. the word neutron means a subatomic particle with no net electric charge and a mass slightly larger that that of a proton . the temperature of neutron star is ...

Speed of DARKNESS !!?

             we all konw about the speed of light, First measured by Danish astronomer Olaus Roemer in 1676 , it was Albert Einstein who realized that light sets an ultimate speed limit for our universe, of 186,000 rip-roaring miles per second ( 299 337.984 Km per sec)  .                  But while the immutability of lightspeed is drilled into physics students at a young age, Einstein’s laws also state that all motion is relative, which got us thinking: what’s the speed of light’s nefarious doppleganger, darkness? The speed of dark? The easy answer is that it’s just the speed of light. Switch off the sun and our sky would go dark eight minutes later. But easy is no fun!          For starters, what we commonly call the “speed of light” is the speed of propagation, and that’s not always the deciding factor. A shadow swoops across the landscape at a speed gover...
