A hidden galaxy IC 342 has captured by NASA's Hubble Space Telescope,which is a challenging cosmetic target. 

Although it is bright,the galaxy sits near the equator of the Milky Way's galactic disk where the sky is thick target.with glowing cosmic gas,bright stars,and dark,obscuring dust.

In order for astronomers to see the intricate spiral structure of IC 342,they must gaze through a large amount of material contained within our own galaxy-no easy feat!

As a result IC 342 is relatively difficult to spot and image,giving rise to its intriguing nickname: "the Hidden Galaxy".

Located very close (in astronomical terms) to the Milky way, this sweeping spiral galaxy would be among the brightest in the sky were it not for its dust-obscured location.

The galaxy is very active,as indicated by the range of colours visible in this NASA/ESA Hubble Space Telescope image,depicting the very central region of the galaxy.

A beautiful mixture of hot,blue star -forming regions,redder,cooler regions of gas and dark lanes of opaque dust can be seen,all swirling together arounda bright core.

In 2003,astronomers confirmed this core to be a specific type of central region known as HII nucleus,a name thatindicates the presence of ionized hydrogen,that is likely to be creating many hot new stars.
