Want to Buy a Telescope?
If you would love to see deeper into space from your own home, you may be interested in buying your very own telescope! Fortunately, Sky & Telescope has some guidelines to help you make this big purchase, as described by Kelly Beatty in her recent article, “How to Choose Your First Telescope.” Here are some highlights […]

The Egyptian Senmut Star Map
The Ancient Egyptians made significant contributions to the field of astronomy. These ancient anstonomers were able to predict solar eclipses based on the passage of the moon between the Sun and Earth during the daytime. The Egyptians developed calendars and star clocks that kept time based on celestial movement. Senmut, the grand vizier of Egypt in […]

An Ode to Gravity
Oh, gravity. You have kept me grounded my whole life. Where ever I have traveled you have kept my feet on the ground and my head out of the clouds. I can not see you but feel your presence in all aspects of life. While some look to defy your laws, I look to embrace […]

Spectroscopy and the identity of elements
Hey Everyone, Today I am going to discuss the details of spectroscopy which explain why different atoms and molecules have different characteristic emission and absorption spectrum. The reason for this unique patterns lies with the the atom’s (or molecule’s) electron energy levels. Each atom and molecule has a unique separation of electron energy levels which […]

Things aren’t always as they appear on the surface
When one looks at the great expanse of the Universe, they will see a mix of moons, planets, stars, and galaxies, but what about all of the open “space” in between these celestial bodies? Most are familiar with the fabric of space-time, which is best described by general relativity, as it illustrates in a logical […]

The Dual Nature of Light
One thing that has always fascinated me about light is that is that it has both wave-like properties and particle-like properties. Intuitively, light seems like a wave, and Young’s double slit experiment – which can and has been recreated easily in freshman physics labs – seems to show “definitively” that it is a wave. But […]

Earth in Infrared
Source: rt.com Two of NASA’s geosynchronous satellites, GOES 13 and GOES 15, have captured infrared light emitted from the Earth, and a University of Victoria graduate student recently used this data to put together a video that shows the behavior of this light over a two month period. Infrared light is generated by heat from the […]

Special Relativity
In physics, special relativity (SR, also known as the special theory of relativity or STR) is the accepted physical theory regarding the relationship between space and time.(Definition from Wikipedia) At the end of the 19th century, Maxwell equations of electromagnetism had been proved by plenty of experiments. However, Maxwell equations are not consistent with the Galilean transformations in Newtonian physics. As a result,…
