The best of northern lights of 2011-2012

Last winter's aurora borealis season got a head start in September after and X2 class eruption on Sun hurled charged particles into Earth.

The northern lights even surpassed the light pollution and covered most of the sky:

Opportunity's latest 360 degree panorama

Below is a spherical panorama shot and stitched by NASA from 817 images taken in Mars by Opportunity rover using the one megapixel Pancam. Images were shot between December 2011 and last June.

It's a false-color image meaning that the colors differ from what human eye would see. As the landscape is mostly orange, using narrowband filters enable the scientist to see better the interesting features of Martian lansdcape.

The local south is located at the visible seam. Above the metal pole is the crater Endeavour, where the little rover visited in 2011. There's lots of dust settled on the solar panels, which will probably be the end of the rover as power output of the panels falls under the threshold needed to operate the vehicle.

There are more (spherical) panoramic images available at Cornell's Pancam site.

The yellow part of the flower reminds a slipper or shoe, hence the flower's name.
