Hello there. I will be talking about Olbers’ Paradox. In the year 1826, the German astronomer Heinrich Olbers’ proposed a controversial question about what makes the night sky dark if the universe contains an infinite number of bright stars (Newton 1). This question fascinates me because every celestial object that can be observed with our eyes, should have an important reason and role to play. The paradox about the night sky was also argued by Kepler as stated in his “Conversations with the…

Intro The universe house's countless dangers. Some are small such as wild fires or sink holes. These natural hazards seem large to us but compered to a black hole they are extremely minute. The idea of earth being swallowed by a black hole is terrifying one. One of the things that we fear most about black holes is how little we know about them. We know that they have incredibly strong gravitational force. By the time you got anywhere near it your atoms would have been ground up and used to fuel…

In the past 15 years, astronomers have achieved leaps and bounds in terms of spotting exoplanets. It had gone from producing no results to being possible. One method, known as Transit, involves continually observing stars and noting whenever spots of it become dimmer. By calculating how much of the star’s light was dimmed, astronomers can also indicate the approximate size of the planet’s radius. It can also tell astronomers what the atmosphere of an exoplanet consists of by looking at the light…

that cannot be directly seen because it does not interact with light. This mysterious matter makes up the majority of mass in a galaxy. Although we cannot see dark matter we know that it is out there because we can see it effecting the motion of the stars in a galaxy and gravitational lensing. The first piece of evidence for dark matter is in the way we have observed galaxies moving. You would likely expect their behavior to replicate that of the Sun and the planets, with the velocity of…

matter and dark energy. Dark matter is the thing that makes it possible for galaxies to exist. When astrophysicists and cosmologist calculated why the universe is structure the way it is, it became clear that there’s just not enough normal matter. The gravity of the visible matter is not strong enough to from galaxies and complex structures. The starts would more likely be scattered all over the place and not form galaxies. Therefore, cosmologist concluded that there is something else inside and…

to fear on Earths end. Normal sized galaxies; such as the Milky Way galaxy, can contain an estimated 400 billion stars. In someone’s mind who knows nothing about Astronomy, they think that the larger the amount of stars, the more crowded the galaxy is. The truth is, that stars and planets are so far apart, the chances of them colliding with each other are small. That…

Did you ever think on how the universe ever started ? It all started in total darkness. An astronomer named Edwin Hubble found out that the galaxies were moving farther away, he knew that by a telescope that he created and it is called the hubble telescope. When the universe exploded it began to spread really quickly and when it exploded the universe had a very high temperature when this happened. Which created formation of elements ,gravity,redshift ,doppler effect,CMB, many more . The big…

Long have we have looked to the stars, be it for navigation, spiritual guidance or shear awe. But, believe it or not, the wonders we see in the night sky with our naked eyes are only a glint of the universe’s enormity, and, as said by Julianne Dalcanton in her 2009 article 18 Years of Science with the Hubble Space Telescope, our hazy atmosphere even limits our ground-based instruments as well. (Dalcanton) Both the incapability of our eyes and our local telescopes hindered astronomy for…

Discoveries about dark matter, high-speed gas clouds, and a small disk around the core are now leading scientists to a new understanding of how our galaxy formed and the way it works, by John S. Gallagher III, Rosemary Wyse, and Robert Benjamin. Our understanding of the Milky Way has come a long way from the time people wove a story about the milk of a goddess spilled across the heavens. About 400 years ago, Galileo Galilei aimed a primitive telescope toward that area and wrote that through it…

The video we watched in lab, “Life and Death of a Star,” gave us incredible information regarding the life cycle of a star. There are billions of stars out there and in our galaxy, we have about four billion. Stars, which are ignited by the power of the atom, burning with light, heat and wrath, stars are anything but peaceful. They collide, devour each other, and explode in enormous supernovas. These “supernovas” are known to be the largest explosion in the universe. Throughout the video, we…
