Keck observatory gives astronomers first glimpse of monster galaxy formation

This image shows observations of a newly discovered galaxy core dubbed GOODS-N-774, taken by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 and Advanced Camera for Surveys. The core is marked by the box inset, overlaid on a section of the Hubble GOODS-N, or GOODS North, field (Great Observatories Origins Deep Survey). (Credit: NASA, ESA)

Opportunity peers out from ‘Pillinger Point’ – Honoring British Beagle 2 Mars scientist

Opportunity Mars rover peers into vast Endeavour Crater from Pillinger Point mountain ridge named in honor of Colin Pillinger, the Principal Investigator for the British Beagle 2 lander built to search for life on Mars. Pillinger passed away from a brain hemorrhage on May 7, 2014. This navcam camera photo mosaic was assembled from images taken on June 5, 2014 (Sol 3684) and colorized.

Trapping light: A long lifetime in a very small place

The top layer shows a simulation of the nanostructure confining the light in the tiny red regions. The second layer is the design generated by an approach that mimics evolutionary biology. The bottom two layers show electron micrographs of the realized nanostructure in silicon. The sharp peak on the left is the trace of the long trapping of light. Credit: Fabio Badolato
