The Sun gives us light and heat, sustaining life on Earth. ... This uneven rotation, coupled with the churning of the upper layers, might well be what produces (by a "dynamo mechanism", described in a later section) regions of intense magnetic field, seen by observers on Earth as dark sunspots. ... Near sunspots those streamers seem to be shaped by the Sun's magnetic field lines, and above the Sun's poles they suggest field lines rising from twin magnetic poles like those of the Earth. ...

Danielson and Kalocsa craters in the Arabia Terra region of Mars were imaged during orbit June 19, 2011, by ESAтАЩs Mars Express High-Resolution Stereo Camera (HRSC). Centered at around 7€ђN and 353€ђE, this anaglyph 3D image has a ground resolution of about 26m per pixel. Data from HRSCтАЩs nadir channel and one stereo channel are combined to produce this 3D image that can be viewed using stereoscopic glasses with redтАУgreen or redтАУblue filters. ...
