The 2010 was a revolutionary year for astronomy. "Complicity" of all this work that have been made to the Hubble Space Telescope, including the introduction of new more powerful cameras and the appearance of revolutionary theories and shocking images from outer space.
One of them is in April, and there I would like to talk.
In this image taken by Hubble Space Telescope is a fantastic and unusual "blob" of gas is greenish appearance and seems to float around the adjoining spiral galaxy.
The bizarre object, called Hanny's Voorwerp (l ' object Hanny in Dutch) is the only visible part of a stream of gas along the beauty of 300 thousand light-years - as our galaxy! - that winds around the galaxy in question, called IC 2947. The greenish Voorwerp is visible because a ray of light from the core of the galaxy's light. But not all within a radius from a quasar - superenergetico an object, which motor ultramassiccio a nice black hole.
This view highlights a handful of stars (the orange area on top of the green blob in the photo). This cluster is confined to an area of \u200b\u200bseveral hundred light years, in which the younger stars have only a couple of million years (if you consider that the Sun, in the middle of the journey of his life, has 5 billion years. ..).
The color green is given by the excitement (bad porche!) delle particelle di ossigeno.
Come può essere nato Voorwerp? Un'interazione tra IC 2947 e un'altra galassia circa un miliardo di anni fa può aver sia prodotto il fiume di gas, sia "acceso" il quasar. L'immagine mostra infatti che IC 2947 è stata disturbata dato che ha complesse volute di polvere cosmica, i due bracci della spirale allargati, e regioni di stelle in formazione attorno al nucleo (nella foto i punti bianchi attorno al centro della galassia): tutti sintomi di una galassia che sta letteralmente "digerendo" una sua simile molto più piccola.
L'oggetto rosa posto tra IC 2947 e Voorwerp è una seconda galassia messa di "taglio", più distante di ciò di cui stiamo parlando.
And they say that the cosmos is boring ... bah.
