Zach Zorich has an interesting piece at Nautilus asking if the world began again, would life as we know it exist? In less than five milliseconds, a Hydromantes salamander can launch its tongue—including the muscles, cartilage, and part of its skeleton—out of its mouth to snag a hapless insect mid-flight. Among amphibians, it is the quick draw … Continue reading If evolution started over, how similar would its results be?

The Fermi Paradox – Wait But Why
The "Wait But Why" blog takes an in depth look at something some of us were discussing on another thread: the Fermi Paradox. Everyone feels something when they’re in a really good starry place on a really good starry night and they look up and see this: Some people stick with the traditional, feeling struck … Continue reading The Fermi Paradox – Wait But Why
Life on the Billionth Rock From the Sun | Seth Shostak
Seth Shostak has an article at HuffPost on asteroids. Not the usual we-need-to-prepare-for-incoming, but discussing something I've noted before that the space age needs: an economic incentive. As some of us have discussed, mining asteroids looks like it might be an excellent candidate. These rocks are a resource. The fact that they're in small chunks makes … Continue reading Life on the Billionth Rock From the Sun | Seth Shostak

We might find extraterrestrial life soon, but intelligent life?
Forbes has an article up noting that many scientists, including Seth Shostak, are now saying that we could find intelligent extraterrestrial life in the next twenty years. I definitely think we might find extraterrestrial life in that time frame, but I'm pretty skeptical that it will be intelligent. I've written about this before, but the … Continue reading We might find extraterrestrial life soon, but intelligent life?
What Makes an Alien Intelligent?
An interesting article in The New Yorker on the necessity of keeping an open mind about what form an alien intelligence might take. Yet, even as the Kepler mission gets closer to finding a mirror image of our own planet, many scientists have ceased believing that we should be looking for ourselves in space. There … Continue reading What Makes an Alien Intelligent?
NASA planning a robotic mission to Europa
Related to my last post on Europa Report, a movie I discovered when I read these articles earlier today, and also in the category of things I somehow missed, NASA is planning a robotic mission to Europa. This is exciting since, as I noted in the movie review, Europa's underground ocean makes it currently the … Continue reading NASA planning a robotic mission to Europa
Europa Report, a review
Somehow I completely missed the release of this movie. It seems to represent the beginning of something I've hoped to see for a while: small independent productions that make use of the lowering cost of CG technology to make narrow genre films. Most film science fiction is, unfortunately, garbage scientifically. The cost and risk of … Continue reading Europa Report, a review
The faster interstellar travel is, the further away intelligent aliens are
Ethan Siegel has an excellent post up exploring the possibility of extraterrestrial civilizations. With hundreds of billions of stars (visible, above, in infrared wavelengths) in our galaxy alone, and literally trillions of planets around them, we have many, many chances for life to have evolved similarly to how it did here on Earth. With at … Continue reading The faster interstellar travel is, the further away intelligent aliens are
How far away is the closest extraterrestrial civilization?
First, let me be clear on what I'm talking about: intelligent aliens with an advanced civilization. This is a different question than extraterrestrial life in general. For life in general, particularly simple life, I'd be surprised if we'd have to look more than a hundred light years from Earth. (We may know the answer to … Continue reading How far away is the closest extraterrestrial civilization?
