Venus Express Adds Evidence For Atmospheric Water Loss On Earth’s Twin

Global view of Venus in a combination of ultraviolet VMC and infrared VIRTIS images.

Observations by the European Space Agency’s Venus Express mission have provided strong new evidence that the solar wind has stripped away significant quantities of water from Earth’s twin planet. The data also shed new light on the transfer of trace gases in the Venusian atmosphere and wind patterns. Continue reading… “Venus Express Adds Evidence For Atmospheric Water Loss On Earth’s Twin”

Herschel opened its ‘eyes’ on 14 June and the Photoconductor Array Camera and Spectrometer obtained images of M51, ‘the whirlpool galaxy’ for a first test observation. Scientists obtained images in three colours from the observation, which clearly demonstrate the excellence of Herschel, the largest infrared space telescope ever flown.

Disruption of planetary oribits could lead to collision with Earth

The solar system’s clockwork motion is by no means guaranteed, for new computer simulations suggests a slight chance that a disruption of planetary orbits could lead to a collision of Earth with Mercury, Mars or Venus in future.

Year 2036: Mars colonization and a date with destiny

Year 2036: Mars colonization and a date with destiny

Dr. Neil deGrasse Tyson host of the NOVA scienceNOW PBS program

From a half billion kilometers away, the message was powerful. In 1994, fragments of the Shoemaker-Levy 9 comet slammed into Jupiter. The earth-size fireballs ejected into space were captured and relayed back to be seen again and again in Internet replay. The message: we need a foothold in space if our species is to survive.

Growing Natural Crystal Furniture

Growing Natural Crystal Furniture 

Tokujin Yoshioka’s chair made from growing natural crystals will headline the exhibition Second Nature opening on the 17th in Tokyo this month. The Venus chair builds on his earlier work such as Honey-pop (2001) which used a honeycombed paper structure to obtain it’s strength and the Pane chair (2006) made of a translucent spongy material called polyester elastomer. The Venus chair is grown in a tank, the production process half controlled by Yoshioka and half left up to nature.
