A Powerful Letter

Posted on February 12, 2018 by astronomydylan

Chapter 3 explained to us how Galileo solidified the Copernican revolution, and sealed the case on how Earth would be viewed in perspective of the universe. In 1615, Galileo wrote a letter to Grand Duchess Christina, in attempt to accommodate his observations’ confirmation of Copernicanism with the doctrines and scripture of the Church. He held … Continue reading A Powerful Letter → Continue reading →

The Map in the Stars

Posted on February 12, 2018 by Nathan Xiao

Getting around is always a difficult task. Even with supercomputers that fit in the palm of our hand and tell us how to get literally anywhere, we still get lost. That being said, it was much more difficult to navigate when all we had were the stars in the sky. Celestial navigation is a craft … Continue reading The Map in the Stars → Continue reading →

Don’t Take Light Lightly

Posted on February 12, 2018 by interplanetira

  When you hear the word “light”, a few things might pop into your mind – the Sun, lightbulbs (or artificial lights in general), or maybe even the colors of the rainbow. What you probably don’t think about are the other forms of light on the Electromagnetic Spectrum. The fact of the matter is that […] Continue reading →

Tides and their effect on human life

Posted on February 11, 2018 by Michael Natinsky

People around the world aim to predict the highest and lowest tides using tide tables. Spring tides happen due to the gravitational pull from both the moon and sun. When the moon and sun are pulling from the same direction, the tide is more intense and this is called a spring tide. This usually occurs … Continue reading Tides and their effect on human life → Continue reading →

Telescopes of All Kinds

Posted on February 11, 2018 by yadavdhruv

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

Posted on February 11, 2018 by alcottastr2110

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 →

Gravitational Waves

Posted on February 11, 2018 by jacobfinesastroblog

Up until recently, the only way we have been able to gather information about stars, galaxies, and the universe around us has been through the study of light. However, as of the last few years, the discovery of gravitational waves provides a new method of collecting information about the universe. Although gravitational waves were first … Continue reading Gravitational Waves → Continue reading →

How do radio waves differ from visible light

Posted on February 11, 2018 by lin0214

Radio waves actually travel at the speed of light in vacuum, which is about 300,000,000 meters per second. It is fast enough for anyone on Earth to contact others on Earth in less a second. Radio waves are electromagnetic waves, so is light. The differences between light and radio waves are their frequencies and wavelengths. Wavelengths … Continue reading How do radio waves differ from visible light → Continue reading →
