Examples

  • In this way VIRTIS succeeded in looking through the thick carbon dioxide curtain surrounding Venus and detected the heat directly emitted by the hot rocks on the ground.

  • Through these ‘windows’ thermal radiation at specific wavelengths can leak from the deepest atmospheric layers, pass through the dense cloud curtain situated at about 60 kilometres altitude, and then escape to space, where it can be detected by instruments like VIRTIS.

  • The reported analysis of the VIRTIS data by Smrekar's team indicates that a number of lava flows on Venus are very young, and that most likely the planet is currently volcanically active.

    Technology

  • The Venus Express Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) measures the spectral emissivity of the surface of Venus in a waveband (around 1 micron) that is weakly absorbed by the atmosphere of the planet.

    Technology

  • Emissivity measurements carried out with the VIRTIS instrument aboard the European Space Agency's Venus Express spacecraft indicate that Venus has been volcanically active in recent geological times.

    Technology

  • Venus, as seen with the VIRTIS instrument on ESA's Venus Express (left) and NASA's Magellan spacecraft (right).

    Technology

  • In the 8 April issue of Science, Suzanne Smrekar, from the Jet Propulsion Laboratory, and co-authors report on an investigation into the surface properties of Venusian hot spots in which they have overlaid the emissivity maps from VIRTIS on radar images and topographical maps of the surface of Venus, and concentrated their attention on the emissivity data from the hot-spot areas.

    Technology

  • Here, and in particular around three of the hot spots (Imdr, Themis and Dione Regiones), VIRTIS data show anomalously high emissivity values.

    Technology

  • Data obtained from VIRTIS last year shows that certain areas deviate from the predictions by as much as two or three degrees.

  • "We are pretty sure that Venus still has volcanic activity," say Jorn Helbert and Nils Muller from the DLR Institute of Planetary Research (Institut fur Planetenforschung) - members of the VIRTIS team.
