Galaxy Wars: M81 and M82 

These two galaxies are far far away, 12 million light-years distant toward the northern constellation of the Great Bear. On the left, with grand spiral arms and bright yellow core is spiral galaxy M81, some 100,000 light-years across. On the right marked by red gas and dust clouds, is irregular galaxy M82. The pair have been locked in gravitational combat for a billion years. Their last go-round lasted about 100 million years and likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays. In the next few billion years, their continuing gravitational encounters will result in a merger, and a single galaxy will remain.

South Of Carina Nebula

With natal dust clouds in silhouette against glowing atomic gas, this colorful and chaotic vista lies within one of the largest star forming regions in the Milky Way galaxy, the Great Carina Nebula. The telescopic close-up frames a field of view about 80 light-years across, a little south and east of Eta Carinae, the nebula's most energetic and enigmatic star. Captured under suburban skies improved during national restrictions, a composite of narrowband image data was used to create the final image. In it, characteristic emission from the nebula's ionized sulfur, hydrogen, and oxygen atoms is mapped to red, green and blue hues, a color palette also popular in Hubble Space Telescope. The celestial landscape of bright ridges of emission bordered by cool, obscuring dust lies about 7,500 light-years away toward the southern constellation Carina.

Also known as the Seven Sisters and M45, the Pleiades lies about 400 light years away toward the constellation of Taurus (Bull).

The arrangement of the spiral arms in the galaxy Messier 63, seen here in an image from the NASA/ESA Hubble Space Telescope, recall the pattern at the center of a sunflower.

A dazzling capture of vivid space-scape by Casey Good. It spans across nebula rich star fields along the plane of our Milky Way. To the north lies the royal northern constellation Cepheus. To the left of centre is (sh) 155 — the Cave Nebula. At VDB 155 at lower right are the Dusty blue reflection nebulae.
