Redshift

As a result of my life experience, nature helped me to become a Christian and look more into the evidence in the universe. The Cosmological and Teleological argument showed that they're evidence of a Creator. The Cosmological is that everything that created has a cause, but there has to be a first cause that was uncaused. More accurately, it “ Whatever begins to exist, has a cause of its existence.The universe began to exist. Therefore, the universe has a cause of its existence” (Cosmological…

There are many astronomers out there, but the one person that stood out to me was Edwin Hubble. It is because of Edwin, we now have a better understanding on the distance in the universe and that it’s expanding. His research was very remarkable that he had a telescope with his name. Since Edwin established the scale of the universe and laid the observational basis, he helped us understand what are galaxies like in the universe. To start off, Edwin noticed a Cepheid variable in the Andromeda…

Super Giant Star: When I was a young star, younger than all of you, just about after was born. I was a small star, didn't have any idea of what was going on. I had a very surprisingly strong gravitational pull, pulling all sorts of gases. Having stronger gravity pulled more and more gas and dust to me. The inner layers of gas and dust start to warm from the pressure of the gas and dust above. Now the star's heat and light blows away the surrounding gas and dust, and then I could finally be seen…

their connection with the earth. They then published their findings in 1929, theorizing that in galaxies light emissions can show that they are moving away from each other move at a constant rate. In other words, Hubble was stating that a galaxy's redshift is almost twice the size as another's when it's almost twice as far from another galaxy. The men's research was widely…

The hubble space telescope Imagine yourself in a world where people don't know what's in the sky or the creation of the solar system? That would be a little scary because you don't ever know what's out there in the solar system if there's a black hole or a meteorite coming for earth. But thankfully we don't have to worry about that because have the best invention ever. The invention of the Hubble telescope has contributed to the growth of space science. Edwin Hubble was born on november 20 1889…

We may not be sending people into space but we can still explore space through the telescopes on and around our planet surveying star upon star looking for answers to the questions that we as a races want answered. Are we alone “Two possibilities exist, either we are alone in this universe or we are not. Both are equally terrifying” Arthur c. Clarke. As we are restrain by are life spans we use robots and unmanned space craft one of the more famous space telescopes we have is Kepler have systems…

In order to find the answer to this question, it must be broken down. What are photons? How does gravity affect light? What is a black hole? A photon is typically seen as a particle or wave representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. Photons are currently best explained by quantum mechanics. However, it is important to know that photons have both the qualities of waves and particles…

1. Describe the Milky Way. What does it contain? The Milky Way is a barred spiral galaxy, which looks like a pinwheel. At times, people can look up to the sky and see the faint band of light, the glow of stars in the galaxy’s disk, which gave the Milky Way its name. The galaxy is of an average size, 100,000 light-years across and 1,000 light-years deep. It contains about 500 billion stars and many planets. The center of the galaxy contains a supermassive black hole, which is the cause of our…

While most of the radiation emitted from a "normal" galaxy is in the form of visible light, like that of the radiation of ordinary stars, AGNs are prominent across the entire electromagnetic spectrum. Thus, astronomers needed to look beyond the visual regime to see their full potential. Recent technological advancements, such as satellite deployment, have enabled astronomers to explore energies once unattainable. In addition to the showing in a wide range of energies, AGNs also change in…

The Little Wanderer Take my love, take my land, take me where I cannot stand. I don’t care, I’m still free, you can’t take Pluto from me. Probably the most debated planet, Pluto was discovered in 1905 by Percival Lowell with predictions calculated through the orbits of Uranus and Neptune. However, Pluto was officially seen and declared as a planet in 1930 by Clyde Tombaugh through a telescope (“Pluto Discovered.”). It has only been recently that we have discovered more about Pluto as the…
