Blueberry Sun Image - Astro-photographer Alan Friedman

Alan Friedman took this image of the sun from his backyard in Buffalo, New York on May 14, 2013 with a 90mm Coronado CaK telescope and a PGR Grasshopper Express 6 megapixel camera. 

He applied a specific colour of extreme violet light called CaK in this image that makes the sun appear to look intensely blue. Friedman then false colour-inverts the image. 

The process highlights the sun’s surface including texture, bright sunspots, and hot active regions appearing dark.

The Grand Spiral Galaxy appears to be spinning through the arc of Arp's Loop in this cool night sky image.

Bernard Miller captured this photo between Feb. 16 and March 14 from Rancho Hidalgo, New Mexico.

The Grand Spiral Galaxy, also called M81, is about 11.8 million light-years away. It is similar in size to our Milky Way and is one of the brightest galaxies in the sky.

In this image, the bright, golden core stands out while the blue and purple arms spiral out from the center.

The faint arc on the top right of the image is called Arp's Loop. Scientists initially thought the loop was material pulled out of M81 by a larger neighbour, M2.

However, later investigations showed the loop could also be part of the Milky Way Galaxy.
