According to the astronomers first everything was an incredibly solid, heavy ball of a matter. This heavy ball exploded billion of years ago and as a result the Universe was formed. The moment of the explosion of this ball is known as “Big-Bang”. After this explosion the early universe was very small and too hot but later it got cooled and it exploded and spread out into the small pieces. Small pieces formed the …
A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined …
What is a Neutron Star.
A neutron star is a stellar remnant–a super-compressed object left over when stars with a mass between 1.4 and about 3 times the mass of our Sun exhaust their nuclear fuel and collapse inwards. The result is a condensed sphere of matter about 20 km across, with a gravitational field approximately 2 x 10^11 times stronger than that of Earth’s.
How Neutron Stars formed.
Neutron stars are formed when large stars …
A Star can be defined as a massive and luminous ball made of Plasma. Basically, a star is formed out of cloud of cool, dense molecular gas. To become a potential star, the clouds need to collapse and increase in density.
Formation of stars can be of two ways: it can either collide with another dense molecular cloud or it can be near enough to encounter the pressure caused by a giant supernova. Several stars can be born at once …
What is a Shooting Star.
A shooting star is another name for a meteoroid that burns up as it passes through the Earth’s atmosphere. In other way we can say that a shooting star is the common name for the visible path of a meteoroid as it enters the atmosphere. A shooting star is also broken pieces of meteors that have become broken off in space.
Most of the shooting stars that we can see …
Brilliant flashes of light in the solar atmosphere, lasting less than an hour, or even perhaps only a few seconds, are called Solar Flares. The brightest are visible in white light, but they are easier to see in the light of hydrogen or calcium lines. A flare is a highly concentrated, explosive release of energy, usually in the vicinity of an active region. Flares spring up in active regions where the magnetic field …
The Sun & major nine planets are the main bodies of our Solar System. In order of increasing distance from the Sun these are Mercury, Venus, earth, mars, Jupiter, Saturn, Uranus, Nepyune & Pluto. Sir William Herschel discovered Uranus in 1781 during a review of the entire sky which was so systematic as to be virtually certain to reveal any such object. A planet more distant from the Sun than Uranus …
No one knows the size of the Universe. No one can tell how big is the Universe. The Universe has no center. So we can’t measure it. According to Astronomers, the universe is still expanding from the time of the big bank. So Universe cannot be measured, and it is continually expanding.
To measure the size of Universe we would need to calculate the decaying rate of expansion, the distance at which stars …
The Universe is a large space that contains everything i.e. all matters and energy, from the smallest particles to the largest particles, whatever in the space is universe. It contains all the planets, stars, asteroids, meteors and all the galaxies. No one knows the size of the Universe. The astronomers believe that the universe is still growing outwards in every direction. Astronomers continue to investigate about it. One way they do this is …
