Extremophiles in Space

Posted on May 1, 2022 by AndreaS

Extremophiles are lifeforms that can survive in what we would consider extreme conditions, such as very hot, cold, acidic, or salty environments. Since the various worlds we have observed in the Solar System are vastly different from Earth, astrobiologists predict that if any lifeforms exist in these places, they would be extremophiles. In this post, […] Continue reading →

Throwing Rockets Into Space Using A Skyhook

Posted on May 1, 2022 by josephmaquino9

One of the biggest issues with rocket launches today is the inefficiency of converting fuel into thrust. Because of this, rocket payloads have to be small compared to the amount of space required for fuel. For instance, the SpaceX Falcon Heavy rocket carries a total weight of fuel of ~411 tonnes (the equivalent weight of […] Continue reading →

Asteroids and nucleotides | blog VIII

Posted on May 1, 2022 by clviggiano

Just five days ago, researchers identified the last two nucleotide bases in asteroid samples that had previously been unrecognized. Professor and researcher Yasuhiro Oba at Hokkaido University in Japan, alongside a team of scientists, successfully identified the missing cytosine and thymine nucleases. Unlike the other bases, Cyt. and Thy. have very delicate structures, making them […] Continue reading →

Bracewell “Messanger” Probes

Posted on May 1, 2022 by josephmaquino9

In 1960, Ronald Bracewell made public his idea of a “Bracewell probe” that was capable of both identifying and exchanging information with intelligent alien civilizations. These probes would be sent toward different star systems and place themselves within a near-circular orbit in a star’s habitable zone. Using solar energy from the star, the probe would […] Continue reading →

Acidophiles, pH, and life on Venus | blog VII

Posted on May 1, 2022 by clviggiano

The pH scale is used to gauge the acidity and ranges from 0-14, with lower values being more acidic and higher values being more alkali. 7 is the neutral level between the two. Substances like battery or stomach acids have pHs around 0 or 1; water and blood are around 7, with drain cleaner or […] Continue reading →

KB’s Astronomical Review

Posted on April 30, 2022 by Karan Bhardwaj

Over the course of the semester, I have significantly improved my understanding of space, the stars within, and the 8 planets of our solar system. It was particularly interesting to me discussing the formation of the solar system, as I had no idea there were so many unique events that shaped our solar system to […] Continue reading →

The Fermi Paradox & Possible Implications

Posted on April 30, 2022 by Karan Bhardwaj

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

Posted on April 30, 2022 by solarelizabeth

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 →

Bracewellvon Neumann Probes

Posted on April 30, 2022 by solarelizabeth

Human space travel is slow and each mission must be meticulously planned. What if there were a way we could learn more about the universe more efficiently? John Von Neumann, in charge of computing the design of a bomb, wondered how else he could use his computing skills. He developed the idea of self-reproducing automation. […] Continue reading →

Blog#8 Final Thoughts regarding Drake equation 

Posted on April 29, 2022 by Irene

Throughout this semester of study, I have been convinced that life on Earth is unique. Although we have only studied the solar system in-depth, the volcanic IO, the freezing Pluto, and the variety of planets and moons with different extremes of weather have furthered my awareness of how unique Earth’s conditions are. Even though planets […] Continue reading →
