Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted one of the farthest, faintest, and smallest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away. This new detection is considered one of the most reliable distance measurements of a galaxy that existed in the early universe, said the Hubble researchers. Hubble detected the galaxy due to the lensing power of the mammoth galaxy cluster Abell 2744, nicknamed Pandora's Cluster. The cluster is so massive that its powerful gravity bends the light from galaxies far behind it, making the background objects appear larger and brighter in a phenomenon called gravitational lensing.

This 300 m-resolution image reveals the human impact on the world?s largest tropical rainforest. The brownish colors indicate deforested areas ? note the distinctive ?fishbone? pattern as main roads are cut through an area, followed by secondary roads for further clearing.
INPE, the Brazilian Institute for Space Research, uses satellites to monitor Brazil?s rainforests. Its results show the annual rate of deforestation has fallen from some 3900 sq km in 2004 to 900 sq km in 2013, although substantial amounts of precious forest are still disappearing every day.
Proba-V is a miniaturized ESA satellite tasked with a full-scale mission: to map land cover and vegetation growth across the entire planet every two days.
The camera?s continent-spanning field of view collects light in the blue, red, near-infrared and mid-infrared wavebands, ideal for monitoring plant and forest growth as well as inland water bodies.
Proba-V?s images are processed and distributed to hundreds of scientific users by VITO, Belgium?s Flemish Institute for Technological Research, extending the coverage of previous generations of the Vegetation camera flown on the Spot-4 and Spot-5 satellites.

Melas Chasma Sulfates
This image offers a view of an excellent contact between layered deposits that postdate the formation of Valles Marineris and possible deposits that predate the canyon\'s formation. The materials are near interior layered deposits that contain sulfates and likely have hydrated minerals. At high resolution, we can have more accurate mapping of the stratigraphic relationships and contacts. Enhanced color can help to differentiate between geologic units and for mapping of sulfates.
This caption is based on the original science rationale.

Comet on 18 October ? NavCam
Four-image montage comprising images taken by Rosetta's navigation camera on 18 October from a distance of 9.8 km from the centre of Comet 67P/Churyumov-Gerasimenko (about 7.8 km from the surface). The image scale is 66.5 cm/pixel, so each 1024 x 1024 pixel frame making up the montage is about 680 metres across.
The individual image frames and more information is available via the blog: CometWatch ? 18 October
