This year has been a spectacular one for exoplanets. New discoveries and new insights have truly pushed the gateway to other worlds even further open.     In the past 12 months we’ve gained increasingly good statistics on the incredible abundance of planets around other stars and their multiplicity. We also finally seem to have [...]

Cosmic Citizens

More interesting than the weather (Credit: Steve Jurveston)

Our remarkable species has existed in its present form for about 100,000 years. That’s about 0.0025% of the total time that we think life has existed on this planet. We, and the vast network of life around us, occupy barely a couple of percent of the volume of this world – its surface, a few [...]

Apparently octopuses can, and do, make quite extended forays into that [...]

Astrobiology Roundup

The Ghost of Astrobiology Past

The range of topics relevant to astrobiology is pretty staggering – from microbial populations, chemistry, geo-chemistry, geobiology, climate, non-linear systems, solar system exploration, robotics, planetary science, exoplanets, astrophysics, and even cosmology. I often call astrobiology an ‘inter-discipline‘, since so much of it is about the connecting threads, the metaphorical synapses between highly specialized areas of [...]

Exomoons ever closer

On a moon, far, far away...

One of the biggest thrills of exoplanetary science is seeing how it combines the new and the old, with every discovery bringing startling perspective on the nature of our own very familiar solar system. I thought I’d dig out a post from the Life, Unbounded archives that helps illustrate this. A freshly edited version of [...]
