The search for extraterrestrial intelligence (SETI) hasn’t yielded much, and some of the results are even a bit embarrassing. We don’t really know what to look for when we’re listening for alien signals. There’s growing evidence that planets like ours are not rare in the universe, but that doesn’t necessarily mean intelligent life is abundant. Given the vast distances to neighboring star systems, we’re also not likely to visit them any time soon.
- Russian billionaire Yuri Milner is spending $100 million on a Breakthrough Listen initiative that will last 10 years and attempt to find alien intelligence. This effort will scan the universe using telescopes that cover more than ten times of the sky compared to previous projects, and the data will be made public for SETI@home distributed analysis. [url]
- NASA has its Nexus for Exoplanet System Science (NExSS) project to look for extraterrestrial life. Identifying exoplanets that might harbor life is a fascinating field that requires an interdisciplinary effort of biologists, physicists, astronomers, geologists and a whole lot of creative thinking.

- No obvious signs of life have been seen after looking at 100,000 galaxies. This probably doesn’t mean anything other than we don’t know what to look for. [url]
