Hubble Chases a Small Stellar Galaxy in the Hunting Dog

The Hubble Space Telescope that is also the largest telescope present in space has chased down another small stellar galaxy NGC 4707. The stunning high-resolution image has great clarity and show smaller stars for the first time. Scientists have used observations from Hubble’s Advanced Camera for Surveys (ACS) for clicking the image.

NGC stands for “New General Catalogue of Nebulae and Clusters of Stars.” It was the renowned astronomer William Herschel who first discovered the bright spiral galaxy named NGC 4707 while examining the sky in clear even April on 1789. He found the galaxy lurking in in the constellation of Canes Venatici or The Hunting Dog located 22 million light years away from Earth.

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.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

The telescope was launched in 1990 and since then it is the largest telescope in space. HST has helped scientists in exploring the deepest corners of the universe and has beamed back millions of stunning shots in its entire career. However, HST will be replaced by the James Webb Telescope in 2018 as it has thrice larger lens when compared to HST.
