Blog 8 – Evidence for a Europan Ocean

Europa, Jupiter’s 4th largest and 2nd closest Galilean moon, is thought to have a large saltwater ocean covered by a layer of ice. An article from Nasa details the evidence for the existence of this ocean. The first piece of evidence is the matching zig-zagging cracks on the surface that indicate that the surface was […] Continue reading

When the Sun Dies

All good things must come to an end, including the ancient (at least relative to humanity), life-giving star we see each day. Even though the sun is considered a young star, it still has a finite lifetime, and it will eventually “die” in about 5 billion years. The image above shows a rough timeline of […] Continue reading

Blog 7:Fermi Paradox

The Fermi paradox is the conflict between the lack of evidence for extraterrestrials and the high estimates for their existence . The name came from the Italian-American Physicist Enrico Fermi. He was roughly quoted as saying “Where is everybody?” This paradox has been explained by saying that the number of intelligent civilizations is very low. […] Continue reading

Astrobiology – Indicators of Life on Other Worlds

Astrobiology studies the past, present, and future of life in the universe. One facet of this interdisciplinary field is considering the possibility of life on other planets or worlds. Scientists utilize research in biology, chemistry, astronomy, and cosmology to help determine if life could exist elsewhere in the universe, and if so, how we can […] Continue reading

What I’ve learned

Walking into astronomy class in late January, I was not even sure if I would be able to name the eight planets in our solar system. It is safe to say that I’ve learned a lot. I think the most important thing I learned is how big our universe really is and how everything explains […] Continue reading

The Future of Space Travel – The Skyhook

Infrastructure is everywhere. Most every way of transport that we consider using regularly has immense infrastructure. Cars have roads, trains have rails and stations, and airplanes have airports and runways. But with space travel, we take the brute force method, spending immense amounts of money and forcing a rocket to defy gravity and get itself …

The Fermi Paradox : Are We Alone?

The Fermi Paradox Picture The universe is magnificently huge, and hence should have countless opportunities for life to develop, but that then begs the question, where are all the aliens? Due to the expansion of the universe being faster than the speed of life, there may be life throughout many galaxies, or even most of …

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

Bracewellvon Neumann Probes

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 #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
