 What Are Comets (comet facts) What we know about comets is that comets are small solar system bodies and they are usually made up of dust, ice and rock particles. These things are key to its nucleus. Observing comets has been a very special place in astronomy. Therefore, in astronomy, comets are divided into several parts: Short Period Comets and Long Period Comets. The orbits of almost all comets are highly eccentric, rising towards the sun and getting hot due to solar radiation and solar winds, from which we can see gas tails. What we know as comet tails, but this process is called outgassing. By the way, it has two tails, a gas tail and a dust tail. Comet tails can sometimes be as long as an astronomical unit.  Short Period Comets (interesting comet facts) Now let's talk about the features of the Short Period Comet, which originally came from the Kuiper Belt or also from the Scattered Disc. Also called periodic comets, their orbital period can be 200 years or less. At the sam

It seems to be one of the most beautiful structures in the universe. It also knows as a name of Messier 101 or M 101. It is a face-on spiral galaxy that is 21 million light years away from us. Pinwheel Galaxy was first discovered in 1781 by Pierre Méchain. Such a structure makes it very special and different from other galaxies. Its properties are very similar to the Andromeda Galaxy.

NASA's Kepler space mission keeps a close eye on thousands of stars at all times, as transit methods are used to search for planets. It has searched many planets so far, its main task is to find Earth-like planets, but in search of this many very strange exoplanets have been discovered. Many of these are also very dangerous exoplanets whose environment can be said to be like hell. In addition, there are some exoplanets that were never expected to be discovered. 1. Kepler -37 b — strange exoplanet Now let's talk about an exoplanet that is only about the size of Earth's moon. It is named Kepler -37 b. The planet was discovered by astronomers in February 2013. The planet is the smallest exoplanet ever discovered to orbit a main sequence star.  Its main star is G-type main sequence star like sun. It is called a Sub-earth by scientists. It has a distance of 15 million kilometers from its star,  which makes it seem unlikely that it will have an atmosphere. At the same time t

1. Pulsating Variable stars are stars in the universe that shrink and expand their outer layers to maintain    balance, Due to which their light fluctuates when viewed from the earth. Omicron Ceti star is its main   candidate. —  Interesting Facts About Stars
