Andromeda

NASA has recently discovered a new planet Yelger in the Andromeda Galaxy. It is the right distance from the sun to support life. It is the same size and mass as Earth. It takes 700 Earth days to revolve around the sun(360 on Earth), and takes 20 Earth hours to rotate around its axis(24 on Earth). It’s temperatures are about the same as on Earth, and has a tilt of 45º. It’s moon is the same distance away from Earth but it twice the mass and size. Because Yelger takes 20 hours to rotate on it’s…

To humans who live on Earth, we perceive Earth as a large mass of land that has been around for about 4.6 billion years. But the Earth is only a small part of what makes up the Universe. Earth is located in the Milky Way Galaxy, and contains billions of stars, which is only a small fraction of the 100 billion galaxies. While the Universe has been around for roughly 13.82 billion years, everyday we learn more and more about the complexities that were once hidden from us. One of the main things…

Local Group. It has about 200 blue stars and about 100 times bigger than Orion Nebula, but is the smallest spiral galaxy in the Local Group. It is believed that there are over 40 billion stars in the M33 and it is currently moving closer to the Andromeda (M31). It is believed that these two have tidally interacted in the past (“Triangulum Galaxy – Messier 33”). Some believe that there was a supermassive black hole in the center of M33 but it does not. The black hole is near the core of the…

Hubble identified a type of “variable star” called a Cepheid in the Andromeda nebula, or known today as the Andromeda galaxy. Hubble was able to discover several of these Cepheids, along with other objects, .and was able to calculate the distance to them from the Milky-Way. Hubble was able to detect nine other new galaxies. Later, in 1925, Hubble…

nebulae. Everything is so far apart. For instance, our moon is 238,900 miles away from the Earth. It is about twice as many miles that someone might walk in eighty years, assuming they walk about 7,500 steps every day. The closest galaxy to us is the Andromeda Galaxy, it is approximately 2.9 million light years away. As long as humans have been alive they have questioned and tried to explain the purpose of the visible pieces of the universe. Egyptians thought that the sun god, Ra, had to deal…

important, because we may gain clues about how stars form, and the origins of the universe. The Andromeda Galaxy, a galaxy that is quite similar to the Milky Way, is approximately 2.5 million lights years away. If you were to look at Andromeda with a telescope, the visible light observed would give an image that is larger than the image of the moon with the same telescope. This means that the Andromeda Galaxy is…

according to the Greeks are based on the same story and share many similarities as well as differences. Although, in both versions the plot follows, for the most part, the same basic points. Perseus, the mortal son of Zeus, slays Medusa, then saves Andromeda with Medusa’s enchanted head, and lastly, kills Acrisius. First, there are vast similarities in both of these versions of Perseus’s amazing tale. In both versions, Zeus descends from the heavens to have an affair with a female relation of…

the sun's location when spring begins, is not far south of the square. To locate features of this area, it may be convienient to imagine that the square is the bowl of a large dipper, having as its handle the line formed by three bright stars of Andromeda (her head and length of body) and a fourth star in Perseus (his hand holding the Gorgon's head). The hind legs of Pegasus appear to make up the constellation of…

Many skywatchers rate October as one of the year’s best observing months. The early sunsets mean that most of the summer’s stars linger in the west late into twilight. Waiting up only a few hours more brings many of winter’s best sights into view in the east, and it’s not too cold yet in the mid-northern latitudes. Even though the Autumn season is firmly in place, not all of the summer Milky Way has been lost. A short drive into the countryside away from city lights will reveal an impressive…

Perseus and his stories have fascinated storytellers and scholars alike for centuries. This mythical man is a hero, born of a god and a mortal and he is credited with many brave and daring acts. Throughout his life, Perseus had an eventful infancy, killed Medusa, slayed a sea monster for his true love, and fulfilled a prophecy. Right from his birth, it was clear Perseus was destined for great things. An oracle told his grandfather, Acrisius, that he would be killed by his daughter’s child.…
