Space Exploration: History, Ethics, and Potentially-Conflicting Interests

But why, some say the Moon? Why choose this as our goal? And they may well ask, why climb the highest mountian [sic]? Why – 35 years ago – why fly the Atlantic? Why does Rice play Texas? We choose to go to the Moon, we choose to go to the Moon in this decadeContinue reading “Space Exploration: History, Ethics, and Potentially-Conflicting Interests” Continue reading

Extraterrestrial Existence

Shouldn’t Earth have been visited by extraterrestrials already? Enrico Fermi, a physicist from Italy, asked the same question in 1950 and sparked a wonderful conversation in the field of astronomy and astrobiology. In 1975, Michael Hart published “An Explanation for the Absence of Extraterrestrials on Earth,” noting that the lack of intelligent life from the … Continue reading Extraterrestrial Existence Continue reading

Astrobiology

Astrobiology is the study of life and the universe and the search for life beyond it. Nasa lists astrobiology as having three questions “How does life begin and evolve? Is there life beyond Earth and, if so, how can we detect it? What is the future of life on Earth and in the universe?” andContinue reading “Astrobiology” Continue reading

Religious Pushback to Science: The Scopes Trial

When you first studied biology, you likely saw a picture like this: Though discussing evolution seems commonplace today, it wasn’t always accepted.  Notably, the debate over teaching it in schools bubbled up in our backyard just under one hundred years ago: the 1925 Dayton, Tennessee, Scopes Trial.  In this post, I’ll tell you about theContinue reading “Religious Pushback to Science: The Scopes Trial” Continue reading

A New Discovery in the World of Extremophiles

Geologists have recently discovered an entire new species of extremophiles among us on planet earth, and the location may shock you. More than 500 km away from nutrients and sunlight, these extremophiles have made a home beneath the Antarctic ice shelf (SOURCE). While this discovery was not meant to actually happen, scientists are pleasantly surprisedContinue reading “A New Discovery in the World of Extremophiles” Continue reading

I Want To Believe!

Forget Fermi’s paradox. Forget the Drake equation. Yet another hot-button topic relating to astronomy and (potential?) extraterrestrial life is- you guessed it- unidentified flying objects (UFOs for short). Do I think it’s kind of a stretch that I’m relating this to chapter 24? Absolutely! But with the (relatively) recent declassification by the Pentagon of three… Continue reading

Theia

For my last blog post I have decided to blog about something close to home. The Theia impact is also called the Big Splash, and is a hypothesis as to how we got our moon. The theory is that a mars-sized planetesimal impacted our proto-earth in its early life. This massive impact essentially shredded TheiaContinue reading “Theia” Continue reading

The Golden Record

In 1977, a cool year for space enthusiasts and film buffs, NASA launched two spacecrafts known as Voyager 1 and Voyager 2. These crafts passed by Jupiter and Saturn, taking advantage of their alignment at that time. Voyager 2 also flew by Uranus and Neptune, and is now traveling across the vast expanse of interstellarContinue reading “The Golden Record” Continue reading

Blog 6 Aristotle’s cosmology

In this blog, I would like to introduce Aristotle’s model of the universe. The cosmic theory from Aristotle is clearly wrong from the view of modern science. However, before modern astronomy was developed, Aristotle’s ideas about our world dominated people’s belief for thousands of years. It was embraced by scholars, philosophers, and religious leaders asContinue reading “Blog 6 Aristotle’s cosmology” Continue reading

Halley in History

Halley’s comet is one thought to have been noted in history millennia before it was ever realized that it was the same comet passing Earth every 75 years. The first official record of the comet’s passing was 239 BCE by Chinese astronomers, but it’s thought that it might have been recorded by the Ancient GreeksContinue reading “Halley in History” Continue reading
