A New Generation of US Spaceflight

A new era of spaceflight is underway in America. The Space Shuttle program was retired in 2011 and ever since, if NASA wants to send an astronaut so space, they must buy a ticket on the Russian Soyuz rocket. But this status quo of depending on another nation to carpool to space is about to … Continue reading A New Generation of US Spaceflight Continue reading

Eratosthenes Measures the Earth

How do you measure the circumference of the Earth? It’s not like you can take out a meter stick and lay it end to end hundreds of thousands of times. Today with satellite technology and GPS we can easily complete this task and get an extremely precise answer: 40,075.017 kilometers. But how might a Greek … Continue reading Eratosthenes Measures the Earth Continue reading

Historical Astronomers in Context

Sir Isaac Newton 1642-1727 Quite a smart man was Newton. He invented calculus. (pause in amazement) He also came up with the aptly named Newton’s Laws of Physics (or the 3 Laws of Motion). These three rules were a significant upgrade to the system astronomers were using at the time. We have the Law of … Continue reading Historical Astronomers in Context Continue reading

2. Galileo revolutionized how we observe the heavens. Although he did not invent the telescope, he used it as a scientific instrument and published his results (Van Helden, 1977). We have built upon his work and have made countless discoveries about space thanks to his work. 3. a. In 1609 Kepler published his laws of planetary […] Continue reading

Historical Astronomers in Context: Johannes Kepler

Johannes Kepler (27 December 1571 – 15 November 1630) is well-known in astronomy for his three laws of planetary motion. He worked for Tycho Brahe where he analyzed Brahe’s observations. Brahe was convinced that the planet’s orbits were circular. However, Kepler could not accept this because Mars did not follow this pattern. He used his and… Continue reading

Historical Astronomers in Context

Sir Isaac Newton improved on Kepler’s three laws of planetary motion by showing how the processes that determine orbital motion also determine motion of objects on Earth. He provided a strong mathematical understanding of these laws and why they worked. In 1666, the Great Fire of London was ignited, destroying as much as 80% of … Continue reading Historical Astronomers in Context Continue reading
