The Fermi Paradox & Possible Implications

Are we alone? This sentence, likely thought by many humans around the world and throughout history in hundreds of languages, brings forth a profound question. Also known as the Fermi Paradox, the search for intelligent extraterrestrial life has captured many minds. If life is so plentiful here on Earth, and there are so many habitable […] Continue reading

Barophiles

The barophiles we have found are tiny organisms, usually bacteria, living in areas with intense pressure. They are found on ocean floors where pressure can reach about 400 atm. For reference, the atmospheric pressure at sea level is 1 atm. Some barophiles known as obligate barophiles cannot survive in low pressures. The barophile Halomonas salaria […] Continue reading

Blog#7 The Fermi Paradox

The famous Fermi paradox is the conflict between the lack of clear, obvious evidence for alien life and various high estimates for their existence (Wikipedia). Since the Universe has an almost infinite amount of stars and planets, given that the chance of having intelligent life is not zero (there is Earth and human beings), it is almost […] Continue reading

Answer to the Fermi Paradox: They Just Don’t Need Us

The Fermi paradox states that due to the relatively high chance of intelligent life existing somewhere else in the universe, they should have visited us by now, except they have not yet. So why? There are currently some explanations ranging from intelligent life just not existing to them not deeming us worthy of participating in […] Continue reading

Blog #7: Sara Seager Ted Talk

I watched the 2015 Ted Talk from Sara Seager (of the Seager Equation) called The Search for Planets Beyond our Solar System. She sets out to introduce what we currently know about our solar galaxy and extra solar planets. She presents a few interesting artist conceptions of the various exoplanets we know of (mainly from […] Continue reading

Arecibo Message

Arecibo message is a radio message that carries information about humans to globular star cluster M13. It was famous for the coding of the message. The message included 1679 binaries, and two prime factors — 23 & 73. When aliens receive the message, they will easily put the signal to the 23 x 73 matrix […] Continue reading

You Live There?

Before humans and animals and even plants dominated the Earth, it was full of prokaryotic life. Extremophiles are types of prokaryotes that can not only survive, but thrive in extreme environments. There are several types of extremophiles. Acidophiles: like acidic environments, (pH levels of 3 and below) Alkaliphiles: alkaline environments, and like pH levels 9 […] Continue reading

Extremophiles

The word extremophile comes from the Latin words extremus (meaning extreme) and philia (meaning love). An extremophile is an organism with the ability to survive, or even thrive, in an environment that we as humans would consider extreme. These organisms are some of the oldest species to exist on Earth. Some of them date back […] Continue reading

The Golden Record: A Message Sent to the Cosmos

In 1977, the Voyager I and Voyager II spacecrafts were launched into space to study the outer solar system. After conducting flybys of the planets in the outer solar systems, the Voyager spacecrafts continued to travel away from Earth, and will eventually travel out of our solar system. With this knowledge, golden records were placed […] Continue reading

Nucleobases in Asteroids

Nucleobases are the building blocks of DNA and RNA. There are five total nucleobases (adenine, thymine, cytosine, guanine, and uracil) and three of the five have been found in meteorites. Recently, the last two nucleobases have also been identified. Th… Continue reading
