Science fiction is filled with unusual alien species. But apart from the occasional robot, biological life is running the show. But NASA scientist, Dr. Steven Dick, sees a future Universe that has evolved past biology. Where every intelligence is artificial. Consider the likelihood of a postbiological Universe.

The departures screen illuminates the stark, disillusioning truth. My connecting flight's 3 hours delayed. Ahh, what is life but for living in the confines of a great, enclosed artificial space where I can watch countless others scurry from one portal to another. Letting luck rule, I meander to the nearest news stand. Fingers slowly trace along the spines, trying to sense the faintest presence of interest. They stop, almost automatically wrapping themselves about the sole piece with promise, the science fiction novel Rollback by Robert Sawyer. This time, fortune did add a nice silver lining to what might have been a very dull wait. (more…) No comments

As predicted, we had a huge number of listener questions after our puzzling trilogy about the nature of space itself. Is the Universe really a big donut? Could you see the same star in all directions? If the Universe is expanding, there must be an edge? Right? Listen in as we decrease the number of headaches by 5, and get a special bonus explanation you can use on the dark matter deniers in your life.

Another new host for the Carnival of Space. This week, the carnival is playing over at "The Martian Chronicles". And so, it's taken on a very Martian theme. But there's more than just plain old Mars, you'll also learn about oceans across the Solar System, inflatable space stations, the hard to find (but easy to see) International Space Station, and more. Click here to read the Carnival of Space #47 And if you're interested in looking back, here's an archive to all the past carnivals of space. If you've got a space-related blog, you should really join the carnival. Just email an entry to carnivalofspace@gmail.com, and the next host will link to it. It will help get awareness out there about your writing, help you meet others in the space community - and community is what blogging is all about. And if you really want to help out, let me know if you can be a host, and I'll schedule you into the calendar. Finally, if you run a space-related blog, please post a link to the Carnival of Space. Help us get the word out. No comments

After 16 days in space and 250 orbits of the Earth, space shuttle Endeavour touched down at Wednesday evening at NASA's Kennedy Space Center in Florida, bringing the STS-123 mission to a flawless end. The mission launched in darkness on March 11, and returned home with a rare night landing – and both were spectacular sights. For those of you keeping score at home, Endeavour's main gear touchdown took place at 8:39:08 p.m. EDT at a mission elapsed time of 15 days, 18 hours, 10 minutes and 55 seconds. (more…) No comments

During a flyby of the small moon on March 12th, the Cassini probe detected significant amounts of organic chemicals as it flew through powerful geyser-like jets of ice blasting into space. This active moon appears to be generating organic chemicals much like the substances found in comets. As Cassini bravely travelled through the plume at a speed of 32,000 mph, it was able to take some indirect measurements of the density of the gas from the surprising amount of torque applied to spacecraft. Fortunately the craft was undamaged as the particles bounced off its bodywork… (more…) No comments
