Every now and then, the NASA/ESA Hubble Space Telescope glimpses a common object — say, a spiral galaxy — in an interesting or unusual way. A sharply angled perspective, such as the one shown in this Hubble image, can make it seem as if we, the viewers, are craning our necks to see over a barrier into the galaxy's bright center.

In the case of NGC 3169, this barrier is the thick dust embedded within the galaxy's spiral arms. Cosmic dust comprises a potpourri of particles, including water ice, hydrocarbons, silicates and other solid material. It has many origins and sources, from the leftovers of star and planet formation to molecules modified over millions of years by interactions with starlight.

NGC 3169 is located about 70 million light-years away in the constellation of Sextans (the Sextant). It is part of the Leo I Group of galaxies, which, like the Local Group that houses our home galaxy, the Milky Way, is part of a larger galactic congregation known as the Virgo Supercluster.

brt.moon @krishna_gupta_bro Your goal is ...Can you look through the Hubble telescope? So, Hubble can see space better thantelescopes on Earth can. Hubble is not the kind of telescope that you look through with your eye. Hubble uses a digital camera. ... Then Hubble uses radio waves to send the pictures through the air back to Earth.

cargsy That seems like a lot of dust. Could our galaxy have a similar amount of dust?
