Hubble Chases A Small Stellar Galaxy In The Hunting Dog
Hubble Chases a Small Stellar Galaxy in the Hunting Dog
by NASA’s Marshall Space Flight Center On a clear evening in April of 1789, the renowned astronomer William Herschel continued his unrelenting survey of the night sky, hunting for new cosmic objects — and found cause to celebrate! He spotted this bright spiral galaxy, named NGC 4707, lurking in the constellation of Canes Venatici or The Hunting Dog. NGC 4707 lies roughly 22 million light-years from Earth. NGC stands for “New General Catalogue of Nebulae and Clusters of Stars.” Over two centuries later, the NASA/ESA Hubble Space Telescope is able to “chase down” and view the same galaxy in far greater detail than Herschel could, allowing us to appreciate the intricacies and characteristics of NGC 4707 as never before. This striking image comprises observations from Hubble’s Advanced Camera for Surveys (ACS), one of a handful of high-resolution instruments currently aboard the space telescope. Herschel himself reportedly described NGC 4707 as a “small, stellar” galaxy; while it is classified as a spiral (type Sm), its overall shape, center, and spiral arms are very loose and undefined, and its central bulge is either very small or non-existent. It instead appears as a rough sprinkling of stars and bright flashes of blue on a dark canvas. The blue smudges seen across the frame highlight regions of recent or ongoing star formation, with newborn stars glowing in bright, intense shades of cyan and turquoise.

GODS AND GODDESSES OF THE ANCIENT WORLD: Enki (Sumerian god of wisdom, water, magic, creation and chaos)
ENKI (also known as Ea, Enkig, Nudimmud, Ninsiku) was the Sumerian god of wisdom, fresh water, intelligence, trickery and mischief, crafts, magic, exorcism, healing, creation, virility, fertility, and art.
Iconography depicts him as a bearded man wearing a horned cap and long robes as he ascends the Mountain of the Sunrise; flowing streams of water run from his shoulders, emphasizing his association with life-giving water, while trees representing the male and female principle stand in the background. The streams are interpreted as the Tigris and Euphrates Rivers which, according to one myth, were formed from Enki’s semen. His name means “Lord of the Earth” and his symbols are the fish and the goat, both representations of fertility.

Stardust in the Perseus Molecular Cloud Image Credit & Copyright: Lorand Fenyes
Explanation: Clouds of stardust drift through this deep skyscape. The cosmic scene spans nearly 2 degrees across the Perseus molecular cloud some 850 light-years away. A triangle of dusty nebulae reflecting light from embedded stars is captured in the telescopic field of view. With a characteristic bluish color reflection nebula NGC 1333 is at left, vdB13 at bottom right, and rare yellowish reflection nebula vdB12 lies at the top. Stars are forming in the Perseus molecular cloud, though most are obscured at visible wavelengths by the pervasive dust. Still, hints of contrasting red emission from Herbig-Haro objects, the jets and shocked glowing gas emanating from recently formed stars, are evident in NGC 1333. At the estimated distance of the molecular cloud, legs of the triangle formed by the reflection nebulae would be about 20 light-years long.
