The discovery that took place in the month of March of the troubled 2020 reached its greatest expressions in the sky towards the end of this past July. The Mission Neowise observed a comet that has been visible to the naked eye; the first in over a decade.
This is a comet that became famous in this peculiar year and that approaches the interior of the Solar System once every 6,800 years. So it is in the category of long period comets.
The C/2020 F3 better known as Comet Neowise
In those days, the end of the visualization of C/2020 F3, better known as Comet Neowise, was nearing. It is estimated that by the end of July its approach to the earth was 54 million kilometers, enough to see it in splendor and enough to be calm.
This is an event that can be seen with the naked eye and has generated many images throughout the world. It is the brightest in recent years which allows its appreciation. The passage of a comet is not a singular event but the brilliance of its tail is its particularity.
What is a comet?
The comets are made up of the mixture of dust, cosmic debris and ice. They are remains in a cryogenic state of planets from 4600 years ago. The dust comes from minerals that have not undergone major changes since their formation and are mostly carbon and silicates.
As for the ice inside it, it is a clear warning of the presence of water in space. Its structure has both monoxide, carbon dioxide and other molecules in it. Some scientific estimates estimate them as time capsules with cosmic characteristics.
How is the tail of a comet formed?
The brightness of its tail is what allows the ease of its observation. The tail of a comet is formed with its own journey through space and reaches completion at perihelion. Actually, there are two tails that make up this part of comets.
The tail of a comet is formed product of gas molecules coming from the coma (this is the cloudiness around the nucleus of the comet). Going back to the tails, one has a bluish appearance and is the most visible. This takes place by alignment around the gravitational field of molecular gases.
In relation to the second one, they are also solids of the size of particles that have been swept away by the solar wind. It is an elliptical shape product of solar reflection in its components. Due to its direction, this tail is also known as anti-tail and is whitish-yellow in color.
Comet Neowise can be seen with splendor
Comet Neowise was visible in splendor before sunrise, its tail so bright that telescopic devices or other devices were not needed to observe it. It is easily located with the help of the Big Dipper located to the northeast.
After this period ended, he continued on his way again to the Oort cloud where he spent 6800 years to visit us again.
