NGC 3314 est constitué de deux galaxie spirales situées dans la constellation de l'Hydre.

It is reddened for the same reason the setting sun looks red. The outer spiral arms of the front galaxy appear to change from bright to dark, as they are projected first against deep space, and then against the bright background of the other galaxy. Gravitational Microlensing in the NGC 3314A-B Galaxy Pair - NASA/ADS Determining the composition of the dark matter that dominates the masses of galaxies is an important unsolved problem, and the results of the MACHO Collaboration suggest that some of Milky Way's dark matter may be in the form of very old white dwarfs.

Through an extraordinary chance alignment, a face-on spiral galaxy lies precisely in front of another larger spiral. William Keel and Ray White III (University of Alabama) in blue and infrared light, combined with new images obtained by the Heritage team in March 2000 using blue, green and red filters. " NGC 3314 a été … The Hubble Heritage color image of NGC 3314 was constructed from archival images taken with WFPC2 in April 1999 by Drs.

Lorsque la lumière traverse un volume contenant de petites particules (molécules dans l'atmosphère terrestre ou particules de poussière interstellaires dans les galaxies), sa L'autre phénomène produit par cet alignement est l'effet de Rougissement de la lumière et effet de microlentilleRougissement de la lumière et effet de microlentilleOn obtient la distance qui nous sépare d'une galaxie à l'aide de la On obtient le diamètre d'une galaxie par le produit de la distance qui nous en sépare et de l'angle, exprimé en NGC 3314 lies about 140 million light-years from Earth, in the direction of the southern hemisphere constellation Hydra. En effet, la lumière provenant de PGC 31532 à l'arrière-plan doit traverser PGC 31531 à l'avant-plan.

The bright blue stars forming a pinwheel shape near the center of the front galaxy have formed recently from interstellar gas and dust. Through an extraordinary chance alignment, a face-on spiral galaxy lies precisely in front of another larger spiral.
Quelquefois, les deux galaxies de NGC 3314 sont désignées comme NGC 3314A et NGC 3314B, mais ces désignations pointent vers des galaxies différentes selon les sources consultées. Galaxy Pair NGC 3314 Galactic Silhouettes (NASA image) "This new image from NASA's Hubble Space Telescope and its Wide Field and Planetary Camera 2 (WFPC2) shows the unique galaxy pair called NGC 3314. The NASA/ESA Hubble Space Telescope has produced an incredibly detailed image of a pair of overlapping galaxies called NGC 3314. Dust lying in the spiral arms of the foreground galaxy stands out where it absorbs light from the more distant galaxy.

Ces deux galaxies sont situées sur la même ligne de visée, mais elle ne sont pas en interaction, car elles sont à des distances très différentes de nous.
The dust lanes are surprisingly pervasive, and this remarkable pair of overlapping galaxies is one of a small number of systems in which absorption of visible light can be used to directly explore the distribution of dust in distant spirals.

Richter indique que NGC 3314A et NGC 3314B font partie de l'Cette galaxie est désignée par NGC 3314B par la base de données NGC 3314B et donc toutes les galaxies du groupe de NGC 3314B font partie de l'La nouvelle image réalisée à partir de plusieurs photos prises par le télescope spatiale Hubble a permis aux astronomes d'approfondir leur connaissance de deux phénomènes physiques grâce à l'extraordianire alignement de ces deux galaxies.

They are separated by tens of millions of light-years of void and are physically unrelated. This silhouetting shows us where the interstellar dust clouds are located, and how much light they absorb. Weanalyze multicolor Hubble Space Telescope imaging, supported byground-based near-IR imaging and fiber-array spectroscopy, to measuredust extinction in the foreground Sc galaxy NGC 3314A, which is backlitby the Sb system NGC 3314B. This line-up provides us with the rare chance to visualize dark material within the front …

The foreground spiral is viewed nearly face-on, its pinwheel shape defined by young bright star clusters. A small, red patch near the center of the image is the bright nucleus of the background galaxy, NGC 3314b. This line-up provides us with the rare chance to visualize dark material within the front galaxy, seen only because it is silhouetted against the object behind it.
