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

Blog 7: Drake Equation
The Drake equation, as we know, has served to estimate the amount of possible intelligent life in the universe. Up to this point, we only know of one, us. We were previously searching for life by looking for radio signals. But obviously, we have not had success with this. Despite this, a new method of […] Continue reading
The Fermi Paradox
“If life is so easy, someone from somewhere must be calling by now.” Nobel prize winning physicist Enrico Fermi, over casual lunch 70 years ago in 1950, asked confronted this very same question (Space). Given the current scientific literature of his time, Fermi realized that the requirements for life are not as elusive or asContinue reading “The Fermi Paradox” Continue reading
