Drake Equation

The Drake equation is an equation used to estimate the amount of civilizations humans can communicate with. The Drake Equation was made by Frank Drake an American astronomer and astrophysicist from Chicago Illinois. The equation takes into factor only planets in the Milky Way Galaxy. The Drake Equation helps try to answer a question we’veContinue reading “Drake Equation” Continue reading

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

Life In The Extremes

If there’s anything I’ve learned in my studies of biology over my education, it’s that life is precarious, delicate, and precious. However, now that I’ve learned more about astrobiology through this course, I’ve also come to know that life is hardy and determined. As Ian Malcom so astutely notes in Jurassic Park, “Life finds a … Continue reading Life In The Extremes Continue reading

How Life Could Start and Exist on Europa

Although our understanding of the evolutionary process is deep, the exact time and process through which the first life forms on Earth arose is still not entirely clear. The panspermia hypothesis speculates that life exists throughout the universe and is distributed through asteroids, comets, and space dust, and that life on Earth was brought fromContinue reading “How Life Could Start and Exist on Europa” Continue reading

Astrobiology, The Future.

Space Travel I am still trying to decide whether my admiration for Elon Musk is because of his electric vehicles (S-3-X-Y) or his passion for space exploration. The topic of space exploration leads me to a scientific field I would like to talk about briefly, Astrobiology. Wikipedia defines Astrobiology as “an interdisciplinary scientific field concerned … Continue reading Astrobiology, The Future. Continue reading

Resilient Life on Earth Increases Possibility of Extraterrestrial Life

Believe it or not, there are organisms on Earth that can survive unimaginable conditions! These beings are called extremophiles, and they’re nothing short of amazing. One example is the tardigrade, which can live in the most extreme heat, cold, dehydration and radiation. The simple fact that these organisms exist give us reason to believe that … Continue reading Resilient Life on Earth Increases Possibility of Extraterrestrial Life Continue reading

Adaptive Archaea

Discovered in 1970, Archaea might be the least well-known of the three domains of life (the others being Bacteria and Eukaryota), but it is a fascinating and diverse group of organisms and quite possibly the first on Earth. Like bacteria, archaea are unicellular, prokaryotic organisms, meaning that they lack nuclei and other membrane-bound organelles in […] Continue reading

A Whole New World!

Because the caves, mines, and crevasses on Earth are filled with extremophiles, NASA uses those lifeforms as a guide to its exploration of the universe. The hidden parts of the planet have to make their own way of survival. Surface life has photosynthesis, but subsurface only a tiny fraction of that energy trickles down so … Continue reading A Whole New World! Continue reading

MEET the home of E.T.?

Liquid water, energy and organic material. According to NASA’s director of planetary science, James Green, these are the major criteria needed for life to form. Green and the rest of his NASA colleagues have also identified four extraterrestrial worlds in our Solar System that hold particular potential for the possibility of life. These worlds encompass one … Continue reading MEET the home of E.T.? Continue reading

Viruses Are An Option

Viruses, microscopic organisms that exist everywhere, consist of genetic material, RNA or DNA that is surrounded by a coat of protein, lipid or glycoprotein. They are classified… Read more “Viruses Are An Option” Continue reading
