The Hubble Space Telescope captured this view of viewing an edge of the galaxy NGC 4013. This photo shows great detail with great clouds of dust and gas extending along the disc of this galaxy. NGC 4013 is a spiral galaxy like our Milky Way located approximately 55 million light years from Earth in the direction of the constellation Ursa Major. From this picture one might think that the galaxy NGC 4013 is a galaxy quite stretched and thin, but is seen across a nearly circular spiral. As an example you can take a CD, if you see the most thin and could not see the above think that the CD is long and thin, but when you see it above, you'll see it is round and larger than at the beginning.

A ring galactic


Someone once said that you should not necessarily rely on what your eyes can see, this is the case of the galaxy NGC 6782, this galaxy has a spiral shape nearly circular, but the photo you see above is far from showing a circular, this photo was taken by the Hubble 01 November 2001 and succeeded in this way to expose the telescope to an ultraviolet vision. As you can appreciate how to vary as I mentioned at the beginning. (Photo: Hubble telescope).



When a galaxy is twisting




The image shown above shows the galaxy ESO 510-G13, which belongs to the category of normal spiral galaxy (like our Milky Way probably) but this shot shows a new structure of the disc form this galaxy, it appears as a twisted if it had undergone major forces that have changed shape, leaving it unusual. This photograph was taken on 02 August 2001. (Photo: Hubble telescope).

Intergalactic Shock


If you look carefully you can see a fairly well-known toward the lower right corner of the photo. Can not seem to be the head of a bird in profile, "well, this is the galaxy NGC 6745 that is colliding with a much smaller galaxy. As you can see, what would be the eye of this bird is the center of this galaxy which has not yet collided. At present the two galaxies are colliding to create the blue luminosities of the contact zone, in what came to represent the bird's beak. This photograph was taken by the Hubble Space Telescope on 02 November 2000. (Photo: Hubble telescope).



A spiral quite useful


The photo shows the spiral galaxy NGC 4414, which served as the "key project" for calculating the ratio of expansion of the universe. This uses the discoveries about the brightness of the stars of this galaxy. The NGC 4414 is located 60 million light years from our planet. The study provided an opportunity to know with certainty that not only speed but also expands the universe able to calculate the age. This photo was taken by the Hubble Space Telescope on June 03, 1999. (Photo: Hubble telescope).


Turning to the rhythm of the clock


When astronomers placed the galaxy NGC 4622, were a great surprise, unlike the other spiral galaxies like NGC 4622 was spinning in the opposite direction to that expected, ie in the same direction they move in a clockwise. This variation in the movement has attracted a large number of additional observations, because although this galaxy to date has shown no major features that distinguish it from other galaxies in the above is striking nearly circular shape. This photo was taken on 05 September 2002.



A matter of perspective


How important might be the perspective in the appreciation of the objects in the sky ", this photograph taken 03 October 2002 shows the spiral galaxy NGC 4319 in the center and the quasar called Markarian 205, without a real perspective you could say they're close, however, we must look to space to see and think in three dimensions, the spiral NGC 4319 is approximately 80 million light years from Earth and the quasar Markarian 205 is 14 times that distance us, ie, approximately 1 billion light years from Earth



Galaxy fertile


Most galaxies form new stars so massive and not very fast, however, there is a class of galaxies known as galaxies "starbust" which have an activity in the formation of stars quite high. The galaxy NGC 3310 is one of these galaxies with high rates of star formation, groups are forming stars at a prodigious rate. NASA scientists have succeeded in identifying the nature of these stars as well as the development of this type of galaxies through the study of the colors shown in the photographs.


Stars everywhere


Nuevas fotografías del telescopio espacial Hubble están brindando a los astrónomos una visión detallada de los brazos y las nubes de polvo de la galaxia espiral Whirlpool, la cual se ha convertido en el lugar de masivos nacimientos de estrellas luminosas. Esta galaxia, también denominada M51 o NGC 5194 está teniendo un encuentro cercano con la galaxia NGC 5195. La cercanía de la NGC 5195 está provocando la interacción de fuerzas gravitatorias que provocan la creación de grupos de jóvenes estrellas brillantes.




One in every hundred


Located approximately 130 million light years from Earth, NGC 4650A is one of the 100 galaxies that have rings. His unusual ring structure has not yet been fully understood. One possibility is that these rings are the remnants of a colossal collision between two galaxies sometime in the past, probably a billion years ago. The remains of one of the colliding galaxies to become a rotating disk with red stars in the center.

While this was happening another smaller galaxy which went very close, was severely damaged or destroyed. During the collision gas were the smallest launched into space and captured by the larger galaxy, forming a new ring of dust, gas and stars which orbit around the inner galaxy almost at right angles to the old disk. What is the end is what you see in the picture, a ring galaxy.



Quite active objects



The Hubble Space Telescope has taken the following photo of a nearby galaxy known as Circinus quite active. This active galaxy belongs to the class of most spirals called Seyferts, which have a compact and is believed to contain massive black holes. Seyferts galaxies are themselves part of a long list of objects called Active Galactic Nuclei (AGN by its initials in English). These have the characteristic of removing gas from the centers of their schools expelled into outer space to very high speeds.
