This image, captured on February 28th by the Helioseismic and Magnetic Imager on NASA's Solar Dynamics Observatory, shows just a few small sunspots. Typically, there are many sunspots during peak solar activity. Below, view a video of February's full solar rotation showing relatively few sunspots. (Photo: NASA)
This year’s solar maximum may be the minimum maximum of the century.
Every 11 years or so, there is a peak in solar activity, such as sun spots, flares and solar winds. For the past eight years, scientists have predicted 2013 to be the maximum of the current solar cycle, but the number of sunspots during these peaks can vary.

Over the past five months, Commander Chris Hadfield has stolen the hearts of millions as he zooms around the Earth’s orbit, sending tweets to internet users far below. These correspondences, like thousands of digital message-in-a-bottles, spanned multiple mediums and ranged from the playful to the poetic. But together, they formed Hadfield’s invitation to the public to join him in his fascination and love of science.

NASA regularly captures unique images of auroras. Click on the photo to see more.
Solar activity — the source of the northern lights — is expected to hit an 11-year peak in 2013. While photographers and sky-gazers across Canada catch the stunning light shows with their heads tilted toward the sky, NASA is capturing images of auroras from a different angle: space.

NASA Earth Observatory has released dazzling images of the earth at night.
The latest images are composites assembled from data acquired by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite, which has orbited the Earth about 14 times a day since it lifted off in October 2011.
NASA Earth Observatory acquired the images using the "day-night band" of the Visible Infrared Imaging Radiometer Suite, which detects light in a range of wavelengths. "Smart" light sensors allow scientists ...

We were poised in Prince of Wales Strait on the East side of Banks Island when we received the email we had been waiting for:
Good afternoon,
It not recommended to go into M'Clure Strait, but there is a window open north of Banks. There is a lead developing ...
