NASA Goes Big and Bold for Exoplanet Science
A United States federal agency is not necessarily the first place you think of when it comes to answering some of the deepest existential questions for our species...
Where Would you Leave a Message From the Stars?
A recent article by Samuel Arbesman in the science magazine Nautilus discusses the extraordinary sounding possibility that – just perhaps – a search for extraterrestrial intelligence could be made by looking at our DNA...
The Grand Texture of Planets
In an idle moment, while staring at a set of solar system data, it occurred to me that it might be interesting to display a set of planetary surfaces on an equal footing, where the overall texture of these worlds was visible (although topography is probably a more [...]..
After a Martian Marathon, NASA's Opportunity Rover Faces Uncertain Future
It's been a long time coming, but this week NASA's Mars Opportunity rover completed the first-ever Martian marathon.
