Explaining Titan’s Alien Weather System

Underneath Titan’s dense atmosphere lies something rather unusual, by terrestrial standards. Some features of the Saturnian moon, at first glance, might look similar to some features we have on Earth — it is the only other body in the solar system with lakes, and appears to have an active weather system. But instead of water, [...]

Water Erupts Across the Solar System

Reading the scientific headlines recently one would be forgiven for thinking that we’re experiencing a bout of interplanetary gastrointestinal distress. First, Saturn’s diminutive moon Enceladus continues to spew what we think are giant sprays of salty water from gnarled creases in its southern icy surface – captured in glorious imagery by the Cassini spacecraft over [...]

Exo-cornucopia

Watch out! There's a lot of stuff up there...

  This has been an extraordinary week for planets (moons), exoplanets, and astrobiology. I’m hard pushed to write properly about all these things but sometimes the sheer tidal mass of discoveries tells its own story.       And tidal masses is the first one up. This week new results from the Cassini mission around [...]

Saturn Is Alive, No CGI

It seems that the Saturnian system just keeps on giving when it comes to amazing imagery. Of course it helps to have a $3 billion space mission in place like Cassini to record everything going on. From Saturn The Movie, to The Austere Beauty Of Other Worlds, and Raw Footage From An Alien World, I’ve [...]

Raw Footage From An Alien World

Swinging around, Enceladus against a backdrop of noise and what may be stars (Cassini raw image)

Have you ever wondered what it would really be like for a person to journey to a truly distant and alien place; another planet, even another planetary system? What kind of things would we first see through our windows, or our cameras? What would our sensory experience be in such a distant realm? Would we [...]

The Austere Beauty of Other Worlds

In the northern winter months we are surrounded by the stark beauty of chilled landscapes. From the darkness of the far north, broken perhaps only by starlight and the glow of aurora, to the brisk grey streets of Manhattan and its now skeletal trees with their claw-like limbs and knobbly stubs pressed to the skies, [...]

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 [...]
