Cool Images of a Hot Star

Astronomers and planetary photographers, both amateur and professional, have been having an inspiring time recently in watching the Sun. Some of the most gorgeous images of our nearest star come courtesy of photographer Alan Friedman. One such spectacular image shows several huge, 50,000 mile high, solar flares, and groups of active sunspots larger than our planet. See more of Freidman’s captivating images at his personal website.

According to MSNBC:

For the past couple of weeks, astronomers have been tracking groups of sunspots as they move across the sun’s disk. Those active regions have been shooting off flares and outbursts of electrically charged particles into space — signaling that the sun is ramping up toward the peak of its 11-year activity cycle. Physicists expect that peak, also known as “Solar Max,” to come in 2013.

A full frontal view from New York photographer Alan Friedman shows the current activity in detail, as seen in a particular wavelength known as hydrogen-alpha. The colors have been tweaked to turn the sun look like a warm, fuzzy ball, with lacy prominences licking up from the edge of the disk.

Friedman focused on one flare in particular over the weekend: In the picture you see at right, the colors have been reversed to produce a dark sun and dusky prominence against the light background of space.
