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

Starwatch: A sister for the Sun?

These clues have been used by a team of astronomers led by the University of Texas to identify the Sun’s potential sibling. Still unnamed but known as HD 162826 or by a number of other catalog designations, it is plainly visible through binoculars high in our summer night sky.

NASA Scientists Recreate Complex Chemistry of Titan’s Atmosphere

This image is a composite of several images taken during two separate Titan flybys in 2006. The large circular feature near the center of Titan’s disk may be the remnant of a very old impact basin. The mountain ranges to the southeast of the circular feature, and the long dark, linear feature to the northwest of the old impact scar may have resulted from tectonic activity on Titan caused by the energy released when the impact occurred.

This artistic representation shows the potentially habitable exoplanet Kapteyn b and the globular cluster Omega Centauri in the background. It is believed that this cluster is the remaining core of a dwarf galaxy that merged with our own Milky Way Galaxy billions of years ago bringing Kapteyn’s star along.
