After I had started my post about the planning phase of the HST up to the start, I have noticed that the arguments (which I thought to be a small section in there) for building a Space Telescope in the first place took up quite some space, so I have decided to post this for

(Immagine, credit: NASA, R. Lucas - STScI/AURA)NEWS SPAZIO :- Guardate bene questa foto. No, non è una stella intorno a cui ruota una nebulosa planetaria. La "ciambella" è un ammasso di stelle. Ed anche la sfera luminosa gialla centrale, anch'essa è un ammasso di stelle! Da togliere il fiato, no?Il telescopio spaziale Hubble ha registrato questa osservazione nel Luglio 2001. Questo oggetto celeste si chiama Hoag's Object (oggetto di Hoag) dal nome dell'astronomo Arthur Allen...

Dark Matter Map in Galaxy Cluster Abell 1689Credit: NASA, ESA, E. Jullo (Jet Propulsion Laboratory), P. Natarajan (Yale University), and J.-P. Kneib (Laboratoire d'Astrophysique de Marseille, CNRS, France)Astronomers have devised a new method for measuring perhaps the greatest puzzle of our universe dark energy. This mysterious force, discovered in 1998, is pushing our universe apart at ever-increasing speeds. For the first time, astronomers using NASA's Hubble Space Telescope were able to ta

Understanding something we can´t see has been a problem that astronomers have overcome in the past. Now, a group of scientists believe a new technique will meet the challenge of helping to solve one of the biggest mysteries in cosmology today: understanding the nature of dark energy. Using the strong gravitational lensing method — where

Who is Edwin Hubble, the guy who gave the Hubble Space Telescope its name? Who is the mysterious guy behind the telescope?Well, actually, Edwin Powell Hubble is not the ‘man behind the telescope' at all. He was born on 20th of November 1889 in the US and studied Physics and Astronomy in Chicago. He then,

No, this has nothing to do with the song by David Bowie, instead aboutthefascinatingandunusualimage takenof the peculiargalaxy that science fiction could have dreamt up. The space oddity, dubbed NGC 4696 (above Click to enlarge), is the largest galaxy in the Centaurus Cluster, located in the constellation of Centaurus. This new snapshot of the galaxy shows a strange arc shape that wraps around itself, and also that extend out into space, scientists have never seen anything l

PR Print Layout heic1013aA cosmic question in NGC 4696PR Video heic1013aZoom in on NGC 4696PR Video heic1013bPan across NGC 4696Curling around itself like a question mark, the unusual looking galaxy NGC 4696 itself begs many questions. Why is it such a strange shape? What are the odd, capillary-like filaments that stretch out of it? And what is the role of a large black hole in explaining its decidedly odd appearance?This picture, taken by Hubble´s Advanced Camera for Surveys, is not just a...

Title this 'Zombie Galaxies' or 'Night of the Living Galaxies.' Astronomers have found mysterious, giant loops of ultraviolet light around old, massive galaxies, which were presumed to be "dead," and these galaxies seem to have come back to life. Somehow these "over-the-hill galaxies" have been infused with fresh gas to form new stars that power

The Coma Cluster is a huge, densely populated cluster, with thousands of galaxies closely bunched together. Amid the bedlam of ellipticals, lenticulars and irregulars is this majestic face-on spiral galaxy known as NGC 4911. Hubble stared long and deep to get this highly detailed image of this particular galaxy located deep within the Coma Cluster.

This stunning new image of the Antenna Galaxies, NCG 4038/39, has been taken by NASA´s Great Observatory. Image Credit: X-ray: NASA/CXC/SAO/J. DePasquale; IR: NASA/JPL-Caltech; Optical: NASA/STScI (Click To Enlarge)The image shows two galaxies, The Antenna Galaxies, situated around 62 million light years away, actually colliding into each other. Due to there being so much empty space inside the galaxy, it is near impossible for any stars to come even close to colliding, and often two collidin...

Here's a Chandra release of the Antennae Galaxies. The compilation of the colliding galaxies is a collaborative effort by Chandra, Hubble and the Spitzer Space telescopes. I've included the press release below, but there is also a video on the Chandra site and you can access more and larger images including desktops so be sure

(immagine, credit NASA/CXC/SAO/JPL-Caltech/STScI)NEWS SPAZIO :- Due galassie che si scontrano, anzi meglio dire che si fondono. E' quello che vediamo in questa meravigliosa (gli aggettivi si sprecano!) immagine composita, a 62 milioni di anni luce da noi. Loro sono le Galassie Antenne e si trovano nella costellazione del Corvo. Sono chiamate cos per via delle lunghe braccia che si estendono all'esterno. La collisione tra le due galassie è iniziata più di 100 milioni di anni fa ed &eg...
