Mars

Many people today like mars because of its varied features and geographical structures. Seriously, anybody who is involved in finding life on other planets other than the earth likes mars because it contains geographical structures similar to earth. Mars is the forth planet from the sun and it appears red in color because of the

The Ultimate Moments After The Big Bang

As I have told you in my previous posts, the universe we have today is different from the past. The universe was started in an inflationary expansion. The universe in the beginning was confined to a point of zero density and volume. But, due to the extreme pressures, it got expanded. It expanded in a

Scientists have discovered a weird astronomical body

Scientists have discovered a weird astronomical body in the Kuiper Belt using the New Horizon’s mission which also examined Pluto. This object is called Arrokoth / mu69 /Ultima Thule. This body consists of 2 astronomical bodies clumped together by a thin neck. This discovery could help nail the mystery of planetesimals. It is thought that

Venus

Venus is the second closest planet to the sun after mercury. It doesn’t have a lot of craters as mercury because it is rebuilt by volcanism. They reshape the surface of the planet. It also remains the hottest planet in the solar system. But, why isn’t mercury the hottest planet if it lies closest to

The Solar System

The solar system is a wonderful place. It consists of eight planets of which four are the inner planets and the other four are outer planets. The inner planets have a solid surface and are otherwise called terrestrial planets. These planets leave the slightest hope of life. They consist- mercury, Venus, earth, mars. There is

Mercury

As the planet is closer to the sun in comparison to the earth, the sun would be three times larger than on viewed from the earth. The sunlight of the sun would be seven times greater than observed on the surface of the earth. Even though, this planet is much closer to the sun than

The Beginning of the Universe

If the universe, had a beginning or not was the question which was swirling all over the scientists’ mind in the 20th century. The clue came in the year 1929 when the astronomer Edwin Hubble (also an athlete) found out that most of the galaxies were shifted towards the red end of the spectra. We

The Birth and Death of the Universe

The universe is a place of wonder. It consists of nebulas, black holes, stars, planets and many more fascinating objects. But did you even wonder how the universe was formed in the first place? I am about to answer that doubt. Before the massive explosion (big bang), the universe was in a very dense point

Five Most Weird and Horrifying planets in the Universe

The universe is billions upon trillions of light years big, so, there should be a lot of horrifying and amazing planets in the solar system. This is a list of the five most horrifying and amazing planets discovered: – COROT-7b GJ 436 b 55 Cancri E Wasp 12b TRAPIST-1b COROT-7b Size of the planet: –

Four Forces of Nature

There are four forces in nature:- Gravity, Electromagnetism, Weak nuclear force and Strong nuclear force Gravity Let me explain Newton’s law of Gravitation Newton’s law of Gravitation states that the force of attraction between any two bodies is proportional to the mass of the bodies and inversely proportional to the square of the distance between

White Dwarf and how it supports itself

A White dwarf is a remnant of a star with very low mass. When a small-sized star ends its life in a supernova (which is one of the brightest explosions because it is visible from earth even if the explosion is hundreds of millions of light years) the star will become a white dwarf. Only

Neutron stars, pulsars, white dwarfs, black dwarfs and magnetars.

A neutron star is a celestial body of very small radius (30 km) and very high density, composed predominantly of closely packed neutrons. Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion, provided that the star is insufficiently massive to produce a black

Death of a Star

Everything needs to die including stars. Stars perform a process called nuclear fusion. In this process they fuse hydrogen, which is the most abundant and lightest gas present in the universe. They fuse this hydrogen into helium which is the second most abundant and light gas. They perform this process to balance against the force

Exoplanets

Exoplanets are worlds beyond our solar system. Thousands have been discovered in the past two decades, mostly with NASA’s Kepler Space Telescope. These worlds come in huge variety of sizes and orbits. Some are gigantic hugging close to their mother stars. Others are icy, some rocky. NASA and other space agencies are looking for a

Planets and moons in the Solar System suitable to support Life

Finding extra-terrestrial life has been a goal for many scientists. You see, life in the earth will end in a century or so, due to various reasons like global warming, nuclear war, robots, etc. NASA and many space agencies are trying to find extra-terrestrial life in the solar system so as for a replacement for

Parts of a star

These are the parts of star: Core The sun’s core is the innermost part. It is the densest and the hottest area in the sun. The core of the sun has a density 10 times to that of lead and a temperature of about 15 million degrees Celsius. Despite high density, the high temperature keeps

Nebula

Nebulae are giant clouds of dust and gases in space. Some nebulae come from the gas and dust thrown out by the explosion of a dying star, such as supernova. Other nebulae are regions where new stars are beginning to form. Let me explain how the stars form in a nebula. When the gases present

Formation of the earth

You would not have wanted to live in the earth before a Mars- sized planet came and collided with the earth which in turn let to the formation of the moon. But this also made changes to the molten earth a very long time ago. The giant impact theory made the earth hotter and noisy.

Black Holes

If you want to die a painful death. Then, choose a black hole. When a very massive star dies, it will puncture space time in such a way that the gravitational pull is so strong that not even light can escape it. Since light cannot escape a black hole, nothing can escape a black hole.

The formation of the moon

If you go back in time, to about 4.53 billion years ago we wouldn’t have had the moon: the earth’s only natural satellite. The moon was formed in about 4.51 billion years ago. Our moon is of importance to us. It makes the tidal waves, which helps the surfers to surf. We are actually lucky
