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 →

Blog Post 7: Drake Equation Odds

Posted on May 1, 2022 by isaachuggins

The Drake Equation is an equation used to determine the odds of communicating with another alien civilization. Created by Frank Drake in the 1961, it was a product of all of the odds of life forming, planets having suitable habitats, and how successful the life was on the planet. The first value was R, or […] 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 →

You Live There?

Posted on April 28, 2022 by Natalie_paige

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 →

The Double Ridges of Europa: An Opportunity For Life

Posted on April 26, 2022 by gcomartin

While looking into climate change related developments on the surface of Greenland, associate professor of geophysics at Stanford University’s School of Earth, Energy & Environmental Sciences Dustin Schroeder noticed small double-ridge formations developing, similar to those observed on the surface of Jupiter’s moon, Europa. The double ridges form when pressurized water from below pushes up […] Continue reading →

Exoplanets

Posted on April 17, 2022 by Kaitlyn Lane

The words in the above picture are hard to make out, but I really liked the visual of some of the known exoplanets graphed on a plot. The color and appearances of these planets are not truly known since we have not directly seen them, but they are inferred based on density, temperature, metal content, […] Continue reading →

Enceladus: Alien Life in Our Own Solar System?

Posted on April 17, 2022 by Quint Gfroerer

Enceladus is an icy moon of Saturn, and is fairly small (or medium-sized, for a moon) with a diameter of about 500 km. For reference, the Moon has a diameter of about 3,475 km. Despite its size, however, Enceladus has been rated as among the most probable sources of life in our own solar system […] Continue reading →

Earth’s Atmosphere and Life

Posted on March 21, 2022 by solarelizabeth

Earth’s atmosphere is conducive to life in a way other terrestrial worlds’ atmospheres are not.  This is because of the greenhouse effect, which keeps Earth warm and allows water to exist in its liquid form. Other planets such as Mercury which do not have an atmosphere or the greenhouse effect are extremely hot during the […] Continue reading →

Extremophiles

Posted on May 4, 2021 by Mykayla

Extremophiles are organisms that not only can survive, but thrive in extreme environments. These are organisms that love the freezing or boiling temperatures, very acidic or very basic conditions, or super high-pressure, salty, or dry environments. There are even extremophiles that hate oxygen and thrive when there is none present. Extremophiles live in places thatContinue reading “Extremophiles” Continue reading →

Our Neighbor the Space Octopus

Posted on May 4, 2021 by brandonlipper

While the potential of finding microorganisms on Mars has intrigued us here on Earth for a while now, more advanced life may live on Jupiter’s fourth largest moon: Europa. In fact, Professor Monica Grady has proposed that, not only is life on Europa likely, but said life may include organisms with intelligence similar to thatContinue reading “Our Neighbor the Space Octopus” Continue reading →
