Astrobiology Roundup


                      Lots of new scientific results in the past couple of weeks feed directly into the central questions of astrobiology – from the search for life, to the environment of interplanetary and interstellar space, and the grand cosmological terrain we find ourselves in. No Methane [...]

Voyager Has Entered The Interstellar Medium


                After many claims and statements over the past few years that Voyager 1, our most distant operating spacecraft, has ‘left the solar system’ (it hasn’t, as I explain here), it does now seem that as of August 2012 this extraordinary vehicle has entered the interstellar medium.

Voyager’s Exit To The Stars…In 17,000 Years


Recent debates over whether or not the Voyager 1 spacecraft has ‘left the solar system’ typically leave out some critical details. The limits of the Sun’s particle radiation is not the physical edge of the contents of the solar system, but it is the point of changeover to the exceedingly tenuous atmosphere of matter and [...]

The Interstellar Internet

An interstellar web? (Original image by B. Torrissen)

A speculative but intriguing discussion that sometimes crops up when talking to people engaged in exoplanetary science goes like this; let’s suppose that we find an unmistakably terrestrial style planet around a relatively nearby star (less than about 30 light years away), perhaps even around one of the Alpha Centauri members, a touch over four [...]

Alone in the blogiverse: where are all the space-art bloggers?

Where are all the space-art bloggers?  When Symbiartic was in the planning stages, this was a post I knew I had to write. There are so few I found it at first surprising.  Do the images from the Hubble trump inspiration in painters?  Is interest in space waning compared to say, paleontology? Science inspired art [...]
