Drake Equation

One of the most interesting things that we have covered this semester is the Drake Equation. This equation uses probability to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy. What I like most about this … Continue reading Continue reading Continue reading

SpaceX

Elon Musk is well known for his innovative publicly-traded companies Tesla and SolarCity. However, it may be SpaceX, the private company that he founded, that has the most promise to change the world. SpaceX made history on Friday (April 8) when it landed … Continue reading Continue reading Continue reading

Halley’s Comet

Halley’s Comet is visible from Earth every 75-76 years. It is the only known short-period comet (a comet that has an orbital period of less than 200 years) that is visible to the naked eye. Halley most recently visited the inner parts … Continue reading Continue reading Continue reading

Jovian Moons…Alien Life?

One question that all humans are curious to find the answer to is: Are we alone in this universe? Based on pure numbers, it is highly probable that life exists elsewhere in the universe. Despite this high likelihood for extraterrestrial … Continue reading Continue reading Continue reading

Climate Change – A Political Battle

The Earth’s climate has undergone changes throughout its 4.5 billion year history. Most of these climate changes can be attributed to small variations in Earth’s orbit that affect the amount of solar energy that the planet receives. Recently, the Earth … Continue reading Continue reading Continue reading

The Gravity Slingshot

Recently we discussed a maneuver called the gravity assist. NASA uses this technique frequently, most notably with the Voyager probe during flybys of Jupiter and Saturn. In simplest terms, a gravity assist changes a spacecraft’s velocity by going through a … Continue reading Continue reading Continue reading

The Hubble Space Telescope

Until this past September when LIGO heard gravitational waves, our knowledge of the universe has come from visual observations. When Galileo began using his telescope in the early 1600s, our notion of the natural world completely evolved. Today, we have telescopes whose … Continue reading Continue reading Continue reading

Historical Astronomers in Context

Isaac Newton (December 25, 1642 to March 20, 1727) discovered the laws of motion and universal gravity which are still taught in introductory physics classes today. These principles allowed him to demonstrate that the physical laws that operate on Earth also operate … Continue reading Continue reading Continue reading

Blog #2 – Midnight Sun

Every morning the sun rises on the Eastern horizon, and every evening the sun sets in the West. I have seen approximately 7800 of these sunrises and sunsets over the course of my life. Every night I go to bed in the dark, … Continue reading Continue reading Continue reading

Blog #1: The Size of the Universe

The size and scale of the universe is extremely difficult for the human brain to understand. It is hard for us to wrap our minds around just how vast and empty space actually is. When we first learn about the solar … Continue reading Continue reading Continue reading
