Zazzle Space Exploration market place
There are advances being made almost daily in the disciplines required to make space and its contents accessible. This blog brings together a lot of that info, as it is reported, tracking the small steps into space that will make it just another place we carry out normal human economic, leisure and living activities.

Scientists find twisting 3-D raceway for electrons in nanoscale crystal slices
more »
An exotic 3-D racetrack for electrons in ultrathin slices of a crystal has been observed for the first time, by a group of researchers. The ultimate goal of this research is to approach the lossless conduction of another class of materials, known as superconductors, but without the need for the extreme, freezing temperatures that superconductors require.

How to power up graphene implants without frying cells

In the future, our health may be monitored and maintained by tiny sensors and drug dispensers, deployed within the body and made from graphene -- one of the strongest, lightest materials in the world. Graphene is composed of a single sheet of carbon atoms, linked together like razor-thin chicken wire, and its properties may be tuned in countless ways, making it a versatile material for tiny, next-generation implants.

Harvest Moon Eclipse
more »
A Harvest Moon rises over Sesimbra Castle south of Lisbon in this impressive series of telephoto exposures. Captured at its full phase, the golden Moon was also gliding through the Earth's more diffuse outer shadow during September's penumbral lunar eclipse. The eclipse shading is subtle compared to a total lunar eclipse. Still, the penumbral shadow does darken the Moon's upper limb, the pale shadow receding as the Moon climbs into Portugal's evening sky. In this eclipse timelapse the effect of sunlight and earthshadow on the Moon looks remarkably like the coloring of light and shadow along the illuminated castle walls.

Brief but powerful outbursts seen from Comet 67P/Churyumov–Gerasimenko during its most active period last year have been traced back to their origins on the surface.
