A week in space: Cassini dips down to Enceladus, a solar flare erupts, Discovery moves, and more

If I lived elsewhere in the multiverse, this is the news and cool space stuff I’d have been covering this week. Unfortunately, in this universe I didn’t have the time. Last weekend, Cassini dipped down close to Enceladus to “taste” the jets that erupt from its surface. For some background on Enceladus, see my entry [...]

Cassini helps us peek underneath the surface of Enceladus

Tiger stripes on Enceladus

The Cassini spacecraft is zooming around Saturn as I type, currently in between two flybys of Saturn’s moon Titan – one was in June, the next will be September. It was supposed to explore Saturn and its moons for only four years between 2004 and 2008. But after two mission extensions it is still going [...]

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 [...]

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 [...]

Two and a half miles beneath the surface of Antarctica’s central Eastern ice sheet is a body of water 160 miles by 30 miles across known as Lake Vostok, after the Vostok research station above it, built by the former Soviet Union in 1957 and now operated by Russia. Even by Antarctic standards it’s a [...]

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, [...]

Water from a Saturnian Moon Rains Down on the Ringed Planet

Enceladus water jets

Enceladus, a small satellite of Saturn, has captivated planetary scientists for years with its watery polar geysers and ridgelike surface features known as "tiger stripes." Now it has a new layer of intrigue. The gas and ice escaping from Enceladus and shooting out from the moon’s south pole in towering jets, which fill Saturn’s diffuse [...]
