Astrobiology

Astrobiology is defined as the study of life in the universe. This includes the universe’s origin, future, and evolution. It includes techniques ranged from astronomy, geology, chemistry, and biology. Studies include not just within Earth, but outside on other planets as well. One of its main focuses is life outside of Earth. This field of […] Continue reading

Is There Life Outside Earth?

A common question many people have asked is if there is life outside Earth and in the Milky Way Galaxy. Current observations and technology have not progressed enough to give a conclusive answer to this exciting and concerning question however people are still searching. One astrophysicist/astrobiologist named Frank Drake came up with an equation to […] Continue reading

The Fermi Paradox

outer space The physicist Enrico Fermi once asked the question “Where is everyone?” on the topic of extra terrestial life. The Fermi Paradox comes from the idea that if the universe is so old and vast why haven’t we found clear evidence of life elsewhere in the universe. When this thought is taken further it […] Continue reading

Tardigrades and extraterrestrial life

I first saw a picture of a tardigrade when I was a child, and even then, I was fascinated. I prefer the more affectionate term “water bear”, and these cute little “micro-animals” are a classic example of just how resilient life can be. As we briefly discussed in class, tardigrades have survived exposure to outer […] Continue reading

The Fermi Paradox Explained

Source The Fermi Paradox describes the contradiction between high and low probability of extraterrestrial civilizations that exist in the universe and the lack of evidence for, or contact with, such civilizations. The term is named after the physicist Enrico Fermi who asked “Where is everybody?” during a conversation about the likelihood of alien life in […] Continue reading

What are the Odds?

The Drake Equation is a formula proposed to estimate the number of technologically advanced civilizations within a given galaxy that may be capable of communicating with us. It doesn’t calculate anything with certainty but, instead, aims to stipulate that if we give X, Y, Z, criteria, what would we expect to see? How many civilizations […] Continue reading

Extremophiles

Image from Cosmos Magazine Extremophiles are organisms capable of living under extreme conditions. This includes but is not limited to extreme temperature, radiation, pressure, and pH level. Given the extremely resilient nature of these organisms, they are some of the most abundant life forms. These creatures are fascinating as they have helped to stretch our […] Continue reading

Life Elsewhere in the Universe?

Picture Credit: Columbia University As generations of humans have looked out on the stars, a never ending barrage of questions has ensued. As we learned that these celestial bodies were stars and planets similar to our own, the natural next question was is there anybody else like us out there? The bad answer is no. […] Continue reading

So Where Is Everybody?

As one may have gathered from reading the many, many pages of “The Cosmic Perspective,” the human race has learned a lot about the universe. We can determine the masses, chemical compositions, and orbital paths of celestial bodies. We’ve identified thousands of planetary systems in outside our own. We know how stars are born and […] Continue reading

Blog 07 – Methanogens

Methanogens are a type of extremophile. While browsing information on extremophiles, these caught my attention because they “ convert inorganic organic compounds into methane and carbon dioxide” (ScienceDirect). These microorganisms prove to be responsible for human flatulence. In addition to their unique productions, Methanogens can be found in the guts of animals, deep marine sediment, […] Continue reading
