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

The Planet 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”

Why do inner planets of our solar system have negligible hydrogen in the atmosphere?

The atmosphere of Earth has 78% Nitrogen and 21% oxygen but no Hydrogen gas. Mercury does not have atmosphere whereas Venus and Mars have an abundance of Carbon Dioxide. This indicates an absence of Hydrogen gas in the atmosphere of inner rocky planets of our solar system. Continue reading “Why do inner planets of our solar system have negligible hydrogen in the atmosphere?”

Reasons for excessive amount of Carbon Dioxide in the atmosphere of Venus

The planet Venus is called the sister planet of Earth because it resembles the Earth in many ways but also different in many properties. The structure and size of the planet Venus are similar to the planet Earth. The difference lies in the temperature and composition of the atmosphere. The temperature of Venus is much larger than planet Earth and sufficient to melt lead. The atmosphere of Venus is so dense that the atmospheric pressure is 90 times the atmospheric pressure on Earth. The equivalent pressure on Earth exists in the oceans at the depth of 1 km. Continue reading “Reasons for excessive amount of Carbon Dioxide in the atmosphere of Venus”

Magnetic Home sustaining life

Magnetic Field protection from Solar wind
Magnetic field of Earth protecting from Solar wind

Everybody is usually familiar with word ‘Magnet’, magnet is a small piece of rock or metal that can attract many types of metals like iron, cobalt, and nickel. The range of application of magnet is also very wide from compass to electronic devices. The magnet creates some effects in the surrounding space that can affect other magnets and metal, this effect is called magnetic field. Magnet interacts with other material through this magnetic field. Continue reading “Magnetic Home sustaining life”

How does Venus protect its atmosphere from solar wind in the absence of Magnetosphere?

The solar wind is composed of high energy charged particle which when interact with planetary atmosphere causes degradation to the atmosphere. The Magnetosphere of planet protects the atmosphere of the planet from these solar winds by deflecting charged particles. For example, the planet Mars has no planetary magnetic field to protect its atmosphere from the solar wind which results in continuous loss of atmosphere to space. The planet Venus is much closer to the Sun Continue reading “How does Venus protect its atmosphere from solar wind in the absence of Magnetosphere?”

Eligibility Criteria of planet for Hosting Life

‘Life’ is one of the most mysterious words. The planet Earth is the only known place where life exists. Astronomers are too keen to know about the existence of life on other places than Earth. Lots of new techniques and experiments are done daily to observe the evidence of life outside the planet Earth. Let us look at some basic requirements for the existence of life on any planet or moon. Continue reading “Eligibility Criteria of planet for Hosting Life”

Amazing Outer Planets with no Surface

Surface of The Planet Jupiter
The planet Jupiter does not have well-defined
surface boundary

Earth is a beautiful planet which has beautiful mountains, valley, rivers, lands, lakes, and plants etc. All these things are present on the surface of Earth. Just imagine the Earth without any surface; you can’t imagine life on Earth if the surface is not present. Continue reading “Amazing Outer Planets with no Surface”

Water outside Earth on the other planets of the solar system

The planet Earth is the only planet where life exists. Water is considered as a vital need for the existence of life on Earth. Earth has water in a large amount which is present in the form of oceans. But the planet Earth is not alone which has water. Other planets and moons also contain water on their surface. Continue reading “Water outside Earth on the other planets of the solar system”

The Great Red Spot Puzzling Astronomers for more than 400 Years

The Great Red Spot (GRS) is an anticyclonic atmospheric storm which is present in the southern hemisphere of Jupiter. Since it is anticyclonic, it is a high-pressure storm opposite to the cyclones present on Earth. It is also called the eye of. The GRS is a very old storm and first observed and described by Giovanni Cassini in 1665. It is believed that it had just formed at that time.
