possibility of life. Out of the billions of galaxies, it’s estimated that only one out of every ten are able to harbor life and only 44 percent of F6-k3 of main sequences stars around our galaxy have the possibility of sustain life (solstation.com). There are certain molecules needed to create and sustain life and only certain stars can harbor life. The possibility of life in the universe has many different factors. Life requires usable energy sources. For organisms on earth, they must be able

Inflation is one of the leading theories explaining the structure of the cosmos, first proposed in 1979 by Alan Guth as a major refinement of the Big Bang theory. In this post, I will explore the basics of inflation as well as how it resolves some problems with the Big Bang theory. The basics Cosmological inflation proposes that between 10−36 and 10−33/32 seconds after the Big Bang singularity, there was an inflationary epoch wherein the universe underwent an immense, exponential expansion of gargantuan

The Research of the Hubble Sequence There are many different classes of galaxies and many more to be discovered Hubble just scratched the surface of what we could find out there. Edwin Hubble is well known for that the research in the Hubble Sequence, also in the many books he wrote for the explonation of his work and his thoughts on it. Edwin Hubble discovered the Hubble Sequence and and was the one who was famos for it. The Hubble Sequence is a theory proven to be a fact by Edwin Hubble, this

The center of the Milky Way is a fascinating region, not solely because of its enigmatic characteristics but also because of its complexities. The center of the Milky Way, initially, was described as a “mini-spiral” of hot gas, however as years passed, scientists have realized that this mysterious center was not a spiral, but a distinct, separate point of radio emission corresponding to the exact center of the Galaxy. This point is referred to as “Sagittarius A* or ‘Sgr A*’” and today, Sgr A* is

amazing and so pretty. He helped Harry Potter and Albus Dumbledore many times. It is called Phoenix constellation because it has the form of a Phoenix. You can look at the Phoenix constellation with naked eyes in the southern sky. It is composed of 74 stars, it is not very bright. To have the best observation you should look at it in autumn. The Phoenix constellation was mostly used in Egyptian and Greek myth, it was created as a link with the sun-god. The Phoenix is a legendary bird who has a very long

The photosphere contains several sunspots and we get to see them in the rising stage in the sunspot cycle. The Sun looks

Venus holds many number two spots in the field of astronomy. It is the second brightest object in the night sky (behind the Moon), second largest terrestrial planet, and is the second planet from the Sun. Venus has an apparent magnitude of -4.6, which is bright enough to cast shadows. It’s so bright that it can also be viewed during the daytime on a clear day. It does take the number one spot for being the hottest planet in our solar system. It was first recorded in the 17th century BC by Babylonian

going to visit 39 light years to a star named Epsilon Capricorni. This star is located in the tail of the Capricornus constellation. We will travel back in time to see it's birth and how it was formed. We will come to the present day star and then predict its future based on scientific research and previous star knowledge. Epsilon Capricorni started only as a cloud of gases and dust particles. The nebula was somehow disturbed by shock waves or solar winds from a star nearby. The gases and dust in the

Stellar Nebula We’ve all seen a star in the night sky, and like most things that aren’t man made, a star has a life cycle. A star is made of mostly hydrogen and helium. The reason a star shines is because it burns hydrogen into helium in their cores. Eventually a star will become a black hole or a white dwarf, and that will be the end of the life cycle for the star. Just like the life cycle has to end somewhere it

According to the article Black holes first, galaxies second it has been found out that each galaxy has a black hole in the center (16). By observing motions of gas it had been suggested that early galaxies were 30 times as huge as central black holes. Therefore, it has been suggested that galaxies are formed around black holes (16). Doppler shifts show the black hole mass. Astronomers believe that both the hole and the galaxies can stop growing (16). As stated in Spinning Hearts of Darkness “Astronomers
