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.
Astronomical Clock in Prague (Maros Mraz) Sitting below the swirling leaves and darkening skies of New York today I realized that yet again our planet is roaring up on perihelion at 30 kilometers a second.
Superimposed image of the Milky Way and Australian Aboriginal engraving of 'The Emu In The Sky' (Barnaby Norris) Scientific illustration has a long and noble history, from ancient depictions of celestial forms to Leonardo Da Vinci's extraordinary drawings of anatomy and invention, to the latest computer-generated animation splashed across CNN or - perhaps with more reflective thought - the cinematic screens of the world's great science museums.
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.
To catch a neutrino (MINOS) For a ghostly type of particle, oblivious to even the massive bulk of a star or planet, neutrinos sure can generate a fuss.
Ghosts in the aether (CERN) The past 24 hours have suddenly been awash in neutrinos, in addition to the 65 billion passing through every square centimeter of your skin every second from the Sun's core.
Deep, deep beneath the ocean waves (USGS/NOAA) Well, ok, perhaps it's not life really in liquid carbon dioxide, but as you'll see it's pretty close.
An imagined habitable planet (Credit ESO/M. Kornmesser) In 1964 Stephen Dole published a hundred and seventy-four page document for a US Air Force project at the RAND corporation in Santa Monica, California.
This extraordinary excerpt is from an upcoming Imax movie that uses Cassini orbiter imagery (NO computer generated images) to create some stunning flybys and flythroughs of the Saturnian system.
Deserving of a quick post is a series of extraordinary time-lapse movies showing the complex motion of jets of matter expelled from baby-stars. Followed for more than ten years by the Hubble Space Telescope these systems are some 1,300 light years from us.
