Summary
DescriptionThe merging galaxy system Arp 220 from ALMA and Hubble.jpg |
English: The compound view shows a new ALMA Band 5 image of the colliding galaxy system Arp 220 (in red) on top of an image from the NASA/ESA Hubble Space Telescope (blue/green). With the newly installed Band 5 receivers, ALMA has now opened its eyes to a whole new section of this radio spectrum, creating exciting new observational possibilities and improving the telescope’s ability to search for water in the Universe.
In the Hubble image, most of the light from this dramatic merging galaxy pair is hidden behind dark clouds of dust. ALMA's observations in Band 5 show a completely different view. Here, Arp 220's famous double nucleus, invisible for Hubble, is by far the brightest feature in the whole galaxy complex. In this dense, double centre, the bright emission from water and other molecules revealed by the new Band 5 receivers will give astronomers new insights into star formation and other processes in this extreme environment. This image is one of the first taken using Band 5 and was intended to verify the scientific capability of the new receivers. The ALMA image includes data recording emission from water, CS and HCN in the galaxies. |

JPEG file comment | The sharp eye of the Hubble Space Telescope's Advanced Camera for Surveys has uncovered more than 200 mammoth star clusters in the heart of the galaxy Arp 220. The clusters are the bluish-white dots scattered throughout the image. The heftiest Arp 220 cluster - about 10 million solar masses - is twice as massive as any comparable star cluster in the Milky Way Galaxy. Arp 220 collided with another galaxy about 700 million years ago, fueling the frenzy of star birth in a small region about 5,000 light-years across. The galaxy is a nearby example of the aftermath of two colliding galaxies. |
