Detection of Habitable Planets
We talked much in class about different methods of discovering extrasolar planets, and Dr. G pointed out to us that the only reason people bother looking for extrasolar planets is to try and find life outside of our solar system. To do this, scientists have to narrow down the list of extrasolar planets into a […] Continue reading
Asteroids: Death, or Life?
Just hitching a ride Most people don’t think of asteroids as the bringer of life to Earth. Actually, for many, it’s the exact opposite. When someone says asteroids many people automatically think about mass extinctions, specifically the extinction of the dinosaurs (which was caused by a large asteroid). However, there is a theory called panspermia which […] Continue reading

Something like acid rain, but a lot worse
captain’s blog, Stardate 69741.0 So we’re spending a lot of time talking about moons lately. If I weren’t so well-educated in the astronomy of our Solar System I would maybe think: “you’re just learning about moons, isn’t that kind of boring?” But I AM so well-educated in the astronomy of our Solar System and know […] Continue reading
A better understanding of our Universe… and maybe aliens
captain’s blog, Stardate 69734.8 In class, we’ve been talking a lot about extrasolar planets, that is, planets that have too many suns. But actually, extrasolar planets, or exoplanets are planets that exist outside our Solar System. Exoplanets are fascinating to learn about because, as much as I love our Solar System, it’s good to get away from […] Continue reading

The Possibility of Life on Enceladus
One question that still excites both amateur and professional astronomers is the possibility of life on other worlds. Certain important elements, however, must be present in order for organic life to exist. Enceladus, one of Saturn’s icy moons, has an underground ocean that may be a source of life, either sometime in the ancient past …

What is the Fermi Paradox?
The Fermi Paradox, first proposed by physicist Enrico Fermi, addresses the question, “where is all the intelligent life in the universe?” It might seem that the answer to this is obvious; life is incredibly rare. But let’s just run a few numbers anyway. The low-end estimate of how many stars are in just in our […] Continue reading

The Fermi Paradox
The Fermi Paradox is a fascinating paradox that asks why, in a universe as vast as ours, we have not seen any other signs of life as of now. There are many different possible explanations and they are all very complex but I will attempt to detail some of them below: One possible explanation is […] Continue reading
Getting really really lucky, or discovering the secret to warp travel
captain’s blog, Stardate 69668.2 This blog post is of the unrestricted variety, so naturally I will take this opportunity to talk about science fiction. One of my favorite things about sci-fi movies is how frequently (and casually) characters from Earth encounter other intelligent species. Or maybe even other species live with us humans here on Earth. […] Continue reading
Are We Alone in the Universe?
And why does that question seem to be so hard to answer? Our universe is vast. There’s no doubt about that. And statistically, we should be able to find life in some way, shape, or form somewhere in the seemingly endless cosmos. For every grain of sand on Earth, there are ten thousand stars in … Continue reading Are We Alone in the Universe? → Continue reading
