The Hubble Space
Telescope has captured an image of a spiral galaxy with bars that can help
understand the Milky Way.
Most of the known
spiral galaxies fall into this category of "slash" - which is defined
by its pronounced structure bars across their centers.
The existence of this
structure can indicate the age of the galaxy.
Two thirds of the
nearest galaxies are young and bar, while only a fifth of the oldest and most
distant have it.
The new image is a
milestone in the long history of the Hubble Space Telescope in the stunning
astronomical imaging.
Bright
galaxy
It is the brightest
galaxy discovered so far, thanks to a device known as gravitational lensing.
This gravitational
lensing occurs when the gravity of a massive object such as the Sun, a black
hole or an entire galaxy, causing a curvature in space-time.
"The gravitational
lens shows how galaxies evolved from ten thousand million years"

The light from distant
objects and bright and magnificent flexes when crossing the region disturbed by
gravity.
At the top left of the
image is a cluster reflecting recent star formation only viewable Hubble
cameras.
The U.S. space agency
said that "this observation provides a unique opportunity to study the
physical properties of a galaxy that is so vigorous, stars when the universe
was only a third of its present age."
Evolution
of galaxies
Hubble's view of the
distant galaxy obtained is much more detailed image that would have been
obtained without the presence of a gravitational lens. This lens shows how
galaxies evolved from 10,000 million years ago, according to NASA.
While the nearest
galaxies to Earth are fully mature and approaching the end of its history as a
nursery of stars, distant galaxies provide testimony to the times of formation
of the universe.
The most distant
galaxies fainter shine not only in space but are much smaller.
