Spiral Galaxy NGC 4319 - A3 Size Photo Print

This is a borderless Space print called "'Spiral Galaxy NGC 4319".

The print has been made on A3 Size (420 x 297 mm, 16.5 x 11.7") matte photo paper. Both the inks and the paper are of archival quality and the paper has a weight of 102gsm.

This is not a glossy print, its a 1440 DPI photo quality matte print. It's a nice print.

Postage on this print is only £1.40 for second class post, and all prints are shipped in a sturdy cardboard tube.

About this image:

Appearances can be deceiving. In this NASA Hubble Space Telescope image, an odd celestial duo, the spiral galaxy NGC 4319 [center] and a quasar called Markarian 205 [upper right], appear to be neighbors. In reality, the two objects don't even live in the same city. They are separated by time and space.

NGC 4319 is 80 million light-years from Earth. Markarian 205 (Mrk 205) is more than 14 times farther away, residing 1 billion light-years from Earth. The apparent close alignment of Mrk 205 and NGC 4319 is simply a matter of chance. Astronomers used two methods to determine the distances to these objects. First, they measured how their light has been stretched in space due to the universe's expansion. Then they measured how much the ultraviolet light from Mrk 205 dimmed as it passed through the interstellar gas of NGC 4319.

The Hubble image shows the inner region of NGC 4319. In addition to the galaxy's inner spiral arms, an outer arm is faintly visible at lower left. The unusually dark and misshapen dust lanes in the galaxy's inner region are evidence of a disturbance, probably caused by an earlier interaction with another galaxy, NGC 4291, which is not in the photograph.

At a distance of 1 billion light-years, Mrk 205 is a relatively nearby quasar. Many quasars reside much farther away. Quasars, once known only as mysterious point-like objects, are now known to be distant galaxies that have extremely bright cores. These powerhouses of light are probably fueled by massive black holes. With powerful telescopes like Hubble, it is often possible to see the quasar's surrounding halo of faint starlight, as is clearly visible around Mrk 205.

Mrk 205 has a companion, a compact galaxy just below it. The objects appear to be interacting. The compact galaxy may be responsible for the structure in Mrk 205's halo.

The Hubble image shows that interacting galaxies and disturbances within galaxies are a rich source of information about galaxy structure and evolution.
