Blog 4: The Sirens of Titan
One of my favorite novels is The Sirens of Titan by Kurt Vonnegut. As the title suggests a portion of the novel takes place on Saturn’s moon Titan, though this fiction is more concerned with the philosophical and not the realistic astronomical. I highly recommend it to fans of science fiction. Discovered in 1655, Titan is Saturn’s … Continue reading Blog 4: The Sirens of Titan Continue reading

Space is vast. In fact, vast enough to contains many million, billions, and trillions of galaxies and other celestial objects. So the ultimate question is, how do scientists keep track of all of the celestial bodies? How do we know that the Andromeda galaxy is coming toward us if we can’t tell if it is… Continue Reading → Continue reading

Radio Telescopes
When someone says “telescope,” you probably think of a long magnifying tube ranging from pocket sized to massive that you can look in an eyepiece of to see things at great distances, such as stars and galaxies in regards to astronomy. Another type of telescope you may not think of is the radio telescope. The … Continue reading Radio Telescopes → Continue reading

Telescopes of All Kinds
Telescopes allow us to view the stars, planets, galaxies, and even quasars in great detail. Before the telescope, astronomers relied on naked eye astronomy, something Tycho Brahe was very good at. It’s really fascinating to learn how these telescopes work. Essentially, there are two types of telescopes – refracting and reflecting. Refracting telescopes use two … Continue reading Telescopes of All Kinds → Continue reading

James Webb Space Telescope
Because of the nature of light, it is evident that the key to learning the secrets of the past is through the use of telescopes. As of right now I believe the most powerful telescope in the world is the Hubble telescope. However, that is set to change in 2019 with the launch of the … Continue reading James Webb Space Telescope → Continue reading

For centuries astronomers have used telescopes to look into the night sky. In 1946 Lyman Spitzer, a prominent astrophysicist in his time, theorized that a telescope placed outside of Earth’s atmosphere would be able to collect much clearer data than telescopes on the surface of the planet. The logic behind his theory is that the … Continue reading Blog Post #2 → Continue reading

The James Webb Space Telescope, or JWST, will be a large telescope that is intended to be the premier observatory of the next decade. The telescope will study every phase in the history of the universe, from right after the Big Bang to the formation of the universe that we know today, and even the … Continue reading James Webb Telescope Continue reading
