Looking Through a Historical Lens

Much of science is the act of investigating phenomena and elaborating on such investigations done by others. This is an incredibly difficult task to accomplish with modern technology. Incredibly though, there is a great source of proof to show that many peoples of the past were able to make some form of astronomical discoveries and […] Continue reading

The New Zodiac

Recently, NASA announced that the Zodiac, as we knew it, was incorrect. Based on current models of the night sky, there should be 13 Zodiacal signs, not 12 as we have been led to believe all of our lives.

In class, we have been doing much work with the Drake Equation, including filling it out ourselves using our own estimates. But…is the Drake Equation useful or even worth our time? If you are […] Continue reading

Doppler vs. Astrometric: Find the Planet

Currently, it’s quite difficult to discover new planets simply by direct observation. This is because the high interference of light caused by the planets’ respective stars makes it almost impossible to detect the light reflected off of planets. However, there are two indirect planet detection methods: Doppler and astrometric. The astrometric method relies on measuring […] Continue reading

Creation of the Kuiper Belt

Recently in class we’ve been talking about the outer portion of our Solar System. Beyond Neptune lies the Kuiper Belt, the disc-shaped region that begins at about 30 AUs and ends around 55 AUs. The Kuiper Belt is home to hundreds of thousands of icy bodies, an estimated trillion or more comets, and Pluto, according to… More Creation of the Kuiper Belt Continue reading
