Based on their discovery and careful brightness measurements of the variable stars in NGC 4414, the Key Project astronomers were able to make an accurate determination of the distance to the galaxy. Despite its high gas density, NGC 4414 is not a starburst galaxy, a fact that could be related to its isolation. Despite its high gas density, NGC 4414 is not a starburst galaxy, a fact that could be related to its isolation. NGC 4414 is a spiral galaxy about 62 million light years away in the constellation Coma Berenices.
NGC 4414 is an unobstructed spiral galaxy about 62 million light years away in the constellation Coma Berenices. NGC 4414 belongs to the Coma I group, a group of galaxies spatially close to the Virgo Cluster. In 1995, the majestic spiral galaxy NGC 4414 was imaged with the Hubble Space Telescope as part of the HST Key Project on the Extragalactic Distance Scale.
What kind of galaxy is NGC 4414?
Wendy Freedman of the Carnegie Institution of Washington Observatories observed this galaxy on 13 separate occasions over the course of two months. The image below is a Digitized Sky Survey 2 (DSS2 – see imprint) image of NGC 4414 taken in the red channel. It was taken by the Hubble Space Telescope in 1995 as part of the HST’s main mission to determine the distance of galaxies, and again in 1999 as part of the Hubble Heritage project. NGC 4414 (also known as UGC 753) is a massive spiral galaxy about 56 000 light-years across, located about 62.3 million light-years away in the constellation Coma Berenices and travelling away from us at a speed of about 716 kilometres per second.
Who discovered NGC 4414?
Wendy Freedman of the Carnegie Institution of Washington Observatories observed this galaxy on 13 separate occasions over the course of two months. The images were taken with Hubble’s Wide Field Planetary Camera 2 (WFPC) through three different colour filters. In 1995, the majestic spiral galaxy ngc 4414 was imaged by the Hubble Space Telescope as part of the HST Key Project for the Extragalactic Distance Scale. In 1999, the Hubble Heritage Team revisited NGC 4414 and completed its portrait by observing the other half with the same filters as in 1995. Wendy Freedman of the Carnegie Institution of Washington Observatories observed this galaxy on 13 separate occasions over the course of two months.
In 1999, the Hubble Heritage Team revisited NGC 4414 and completed the portrait by observing the other half with the same filters as in 1995. In 1999, the galaxy was completed by a rare and spectacular head-on collision with one of the other two galaxies you see on the right.
What is the overlap of NGC 3314?
This unique alignment gives us a rare opportunity to visualise dark material within NGC 3314a that can only be seen because it stands out from the object behind it. NGC 3314 is a pair of overlapping spiral galaxies in the constellation Hydra at a distance of 117 to 140 million light years. NGC 3314 is actually a pair of overlapping galaxies located 117 million (NGC 3314A) and 140 million (NGC 3314B) light years away in the southern constellation of Hydra. The deformed shape of NGC 3314A, seen mainly below and to the right of the core where streams of hot blue-white stars extend from the spiral arms, is not due to an interaction with the galaxy in the background.
How many galaxies are there in the universe?
The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1, 25×101) galaxies in the observable universe. It belongs to a group of at least 54 objects called the Local Group of Galaxies, a name Hubble gave to this local cloud of objects when he mapped the nearby cosmos. For the first galaxies ever, this should be taken to extremes, and it still applies, as far back as we have ever seen. According to NASA, galaxies show how matter has organised itself in the universe – at least on a large scale.
However, astronomers are still working out the details, such as why elliptical galaxies follow certain patterns in terms of brightness, size and chemical composition.
