Life in the universe is a fascinating topic. The simplest question: Are we alone? It breeds so many deeper and more profound scientific questions, like “How many habitable planets are there?” “How likely is life to develop on any given planet?” and “How long can a civilization survive?” We can’t answer them definitively, but we can narrow it down. The Drake equation, shown above, was first developed by Frank Drake, the head of the Search for Extraterrestrial Intelligence (SETI), in 1961. He took the question of are we alone and made it quantifiable, in a probabilistic way. It lets us...
This story popped up yesterday, and I can imagine it will go far, since it talks about life in the universe. I get it, it’s what people are interested in, and at least this story is focused on the science of why this is the best place to look for intelligent civilizations, instead of “Oh hey there’s a strange ring of material around a star, must be an alien superstructure.” But I digress. So where is the best place to look for life in the universe? The answer is in a Globular Cluster. A globular cluster is one of the...
Sometimes I love to say ‘I told you so,’ though in the world of science it’s more like ‘I gave you a high probability of this plausible scenario.’ A little while back a story broke about a star called KIC 8462852, with a strange ring of material surrounding it. One potential explanation was that an extraterrestrial civilization has constructed a giant ring to harvest it’s home star’s energy. Though this was one of a dozen possible explanations, it of course gathered the most steam among the general populace. In a statement today, officials from the Search for Extraterrestrial Intelligence (SETI) confirmed that...
