In 1950, Enrico Fermi famously asked: “Where is everybody?” With humanity’s rise in technological progress, we could colonize the galaxy within a couple million years. If we apply the Cosmological Principle (We are not special) to our galaxy, the cosmos should be crawling with life. With over half a trillion planets in our…Read more Take Me To Your LeaderContinue reading → Continue reading
Earth is the only planet in our universe that we currently know supports life. For a planet to harbor life as we know it, it must lie in a star’s habitable zone. Being positioned in the zone is not enough, however. Countless planets orbit their suns at the proper distance and do not…Read more Not Too Hot, Not Too ColdContinue reading → Continue reading
From Earth’s birth 4.6 billion years ago, it has been through some violent trauma. From worldwide ice ages and raging fire storms, it is a wonder that we made it here in one piece….or most of us. Asteroids regularly come in contact with Earth, wreaking havoc on the surface below. These meteors interfere with nature’s…Read more Chaotic EarthContinue reading → Continue reading
The search for exoplanets is one of the most exciting projects in science today. The possibility of earth-like worlds harboring intelligent life is what has electrified most science fiction geeks. With enough funding, the possibilities are endless! Our ability to detect these elusive worlds has improved since our first discovery two decades ago. In late…Read more Life On Other WorldsContinue reading → Continue reading
The planets of the Solar System dramatically vary from massive gaseous, ringed giants to miniature rocky terrestrials. The celestial bodies are also at such great distances that no map of our Solar System can truly illustrate both the distances and relative sizes to scale. The terrestrial planets are relatively similar in size and composition, but…Read more The Terrestrial WorldsContinue reading → Continue reading
Gravity on Earth acts on all objects with the same force. No matter their mass, objects fall and accelerate at a constant rate. Due to the air resistance of different shapes, this is not always apparent. On a planet or moon lacking oxygen, the law could be simpler to demonstrate. On Earth, falling objects…Read more The Earth’s GravityContinue reading → Continue reading
Visible solar eclipses are relatively rare phenomenon to witness. They occur whenever the moon gets between the Sun and the Earth. The eclipse must occur with a new Moon to completely blot out the Sun. Because the Moon must be in the right location and phase, these eclipses don’t happen very often. There are three…Read more 2017 Solar EclipseContinue reading → Continue reading
