Amazing View Of A Disc Galaxy - Our Galaxy Milky Way Is Similarly Thin!

in technology

Heard about thin disk galaxies? Imagine how it will look if you see it horizontally through the edge. That is exactly what you see in this image taken from Hubble telescope.  What if our Galaxy is this thin? You won't believe it, infact Milky Way is thought to be this thin.

 

 You would think why is there a line segment on the sky? In one of the more precise alignments known in the universe, what is pictured  is  a disk galaxy being seen almost perfectly edge on. The image from the Hubble Space Telescope is a spectacular visual reminder of just how thin disk galaxies can be. NGC 4452, a galaxy in the nearby Virgo Cluster of Galaxies, is so thin that it is actually difficult to determine what type of disk galaxy it is. Its lack of a visible dust lane indicates that it is a low-dust lenticular galaxy, although it is still possible that a view from on top would reveal spiral structure. The unusual stellar line segment spans about 35,000 light years from end to end. Near NGC 4452's center is a slight bulge of stars, while hundreds of background galaxies are visible far in the distance. Galaxies that appear this thin are rare mostly because our Earth must reside (nearly) in the extrapolated planes of their thin galactic disks. Galaxies that actually are this thin are relatively common -- for example our own Milky Way Galaxy is thought to be about this thin!
