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?

It’s time to look for life in Europa’s ocean
Lee Billings has a fascinating article up at Aeon asking why we continue to send missions to Mars when the best chance of life existing today is in Europa's underground ocean. If Europa is alive, if some biology dwells within those dark waters, the implications would be even more staggering than finding life on Mars. … Continue reading It’s time to look for life in Europa’s ocean
SpaceX Successfully Soft-Lands on Earth for First Time. Is Mars Next?
The other day, I noted that there wasn't much information on what had happened with the SpaceX soft landing. Now there is a bit more, and it sounds promising. In addition to maybe saving 70% of launch costs, the technology could have benefits for future Mars landings. After flying to the edge of space, a … Continue reading SpaceX Successfully Soft-Lands on Earth for First Time. Is Mars Next?
Americans keen on space exploration, less so on paying for it | Pew Research Center
Many Americans are optimistic about the future of space travel, but they don’t necessarily want to pay for it. It’s been that way for some time, actually. A Harris survey taken in 1970 – less than a year after the first moon landing – showed that a majority (56%) thought the landing was not worth the money spent. … Continue reading Americans keen on space exploration, less so on paying for it | Pew Research Center
Reusable rockets: Up and down and up again
A while back I highlighted SpaceX's reusable first stage. Last week, they launched with it with the plan to have it do a controlled descent into the waters off Cape Canaveral. I haven't been able to find detailed reports of how well it worked, other than this snippet from their web site. Data upload from … Continue reading Reusable rockets: Up and down and up again
Max Tegmark posts his chapter on cosmic inflation online
If you enjoyed my write up on Tegmark's Level II multiverse, you might enjoy this guest post that he makes on Sean Carroll's blog, which includes a link to the chapter on inflation from his book, including those visual aids I referenced! Since the BICEP2 breakthrough is generating such huge interest in inflation, I’ve decided … Continue reading Max Tegmark posts his chapter on cosmic inflation online
The flower-shaped starshade that might help us detect Earth-like planets
Pretty cool. Jeremy Kasdin in this TED talk discusses an idea to remove the glare of a star's light in order to possibly get a look at its planets. http://www.youtube.com/watch?v=XYNUpQrZISc
First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories — ScienceDaily
This is a pretty big milestone. The first Earth sized planet in a star's habitable zone. Pity it's so far away (500 light years) that spectral analysis probably won't be possible to figure out what its atmosphere has in it. The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed … Continue reading First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories — ScienceDaily
Tegmark’s Level II Multiverse: bubble universes
I recently finished reading Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the second in a series of posts on the concepts and views he covers in the book. Tegmark postulates four levels of multiverse. In the first post of this series, I described Termark's Level I … Continue reading Tegmark’s Level II Multiverse: bubble universes
Minimum crew size for an interstellar generation ship
John Hawks takes a look at a fascinating article in Popular Mechanics that looks at what the minimum crew size would need to be for an interstellar generation ship, and relates it to what is known about genetics in anthropology. Popular Mechanics asks, "How Many People Does It Take to Colonize Another Star System?". The basic problem … Continue reading Minimum crew size for an interstellar generation ship
