  • This composite of C/2013 A1 (Siding Spring) merges Swift UVOT images taken between May 27 and 29, 2014. Sunlight reflected from the comet's dust, which produces most of the light in this image, appears yellow; violet shows ultraviolet light produced by hydroxyl (OH), a molecular fragment of water.

  • In 2001, GOCE delivered a model of the 'geoid' (Earth's gravity field) pictured here. At the time, it was the most accurate ever produced. The colours in the image represent deviations in height (–100 m to +100 m) from an ideal geoid. The blue shades represent low values and the reds/yellows represent high values. Credit: ESA/HPF/DLR
    Data from an Earth-observing satellite has provided unexpected evidence that ice loss in Antarctica has had a noticeable effect on Earth's gravity.

  • Image of patchy wrinkle structures from an outcrop. Ridge (upper right corner) and Pit (center) wrinkle structures are present on the same bedding plane. Swiss Army knife for scale. The location is the Upper Cambrian Big Cove Member of the Petit Jardin Formation, near Marches Point on the Port au Port Peninsula in western Newfoundland. Credit: Image courtesy of Giulio Mariotti
    A new study sheds light on how geological features known as wrinkle structures are formed. It involves a bed of sand, waves and microorganisms.

  • High circular polarization (the red and white regions in the image) observed in the infrared light from reflection nebulae in the star-forming region Orion OMC1 (Bailey et al. 1998). It is caused by alignment of the dust particles in magnetic field, but can be responsible for formation of homochiral organics in these dust particles.
