Comets, the Dirty Snowballs of Space

Comets are pretty spectacular occurrences in space and I really hope to see one some day. They are described as dirty snowballs because they are made up of ice of different kinds, but mostly water as well as rock and dust mixed together. They can be a few hundred meters to a few kilometers in diameter and their tails can extend for large distance, even longer than the sun's diameter in some instances. The comet also has a thin atmosphere of it's own called a coma. They generally move in an elliptical orbit which passes around the sun and into the outer solar system, which is why we get see them, but not the same one very often.

As the comet gets closer to the sun, it warms up and sometimes there are jets of gas released from the comet, almost like a geyser, which can make the comet spin. The ice also sublimates as it approaches the sun because of the different gasses that form the ice. Sublimation is like evaporation, except it is when a solid substance turns into a gas directly, not a liquid to a gas. This is part of what forms the coma and the solar winds from the sun are what blow the gasses from the coma away from the sun forming the tail. A comet generally has two tails, the one can easily be seen with the eye because it is made of dust and the second tail can be seen in pictures because it is a tail formed by plasma. From my understanding, plasma is the fourth state of matter, and occurs when a gas is energized a whole lot. This makes the gas into an extremely conductive substance and occurs naturally when lightning strikes.

I would really like to see a comet one day as there was a big one called Hyatake (in the picture above) that could be seen from earth a month before I was born.

Hope you enjoyed the post!

Thank you for the useful post. Continue in the same direction.

i am following u now follow me back @tanvirsadatripon

wow its amazing the more we know about nature the more we lost

There are also a few that I would like to see, but something a bit closer to earth which would also be spectacular to see is the aurora borealis...maybe one-day.

Aurorea Borealis is high on my list. I am planning a trip to Iceland in hopes to see one.

I really hope you make it and that it will be great!

The Aurora really does seem amazing and I would love to see one some day.

nice post and thanks for all those nice information and
some time check my profile @tanvirsadatripon

Thanks, I am glad that you liked it.

Awesome job! Comets are a beauty of this universe for sure! Some people believe if you make a wish when you see them, your wish comes true. Don't know about that :)

There are also 2 great ways to describe a comet in my language (turkish). One is kirli kartopu which means "dirty snowball", and the second one is buzlu çamur topu which means "icy dirtball". Don't know where these come from but i find it quite fascinating :)

Keep on posting inspiringly, i'll be sure to follow you!

Cheers.

Thanks. I love the description of "icy dirtball", it is a great way to describe them.

Comets are so amazing
