Milky Way image reveals detail of a billion stars

29.03.2012
More than one billion stars in the Milky Way can be seen together in detail for the first time in an image captured by astronomers.

Scientists created the colour picture by combining infrared light images from telescopes in the northern and southern hemispheres. Large structures of the Milky Way galaxy, such as gas and dust clouds where stars have formed and died, can be seen in the image.

The picture represents part of a 10-year project involving scientists from the UK, Europe and Chile, who gathered data from the two telescopes. The information has been processed and archived by teams at the Universities of Edinburgh and Cambridge, who have made it available to astronomers around the world for further studies.

Archived information from the project – known as the VISTA Data Flow System – is expected to enable scientists to carry out groundbreaking research in future years without the need to generate further data.

The image is being presented at the National Astronomy Meeting in Manchester today (Thursday 29 March). It shows the plane of the Milky Way galaxy, which is often described as looking like two fried eggs back-to-back, with a flat disc in the middle. Earth is close to the edge of this disc, and the image shows a cross-section through the disc as seen from Earth's perspective.

It combines data from the UKIDSS/GPS sky survey taken by the UK Infrared Telescope in Hawaii with the VVV survey from the VISTA telescope in Chile.

Astronomers used infrared radiation instead of visible light to enable them to see through much of the dust in the Milky Way and record details of the centre of the galaxy.

Scientists have published the image online with an interactive zoom tool that reveals the detail within. Zooming into the image reveals a tiny fraction of the entire picture, which alone contains more than 10,000 stars.

The work was supported by the Science and Technology Facilities Council.

Dr Nick Cross, of the University of Edinburgh's School of Physics and Astronomy, said: "This incredible image gives us a new perspective of our galaxy, and illustrates the far-reaching discoveries we can make from large sky surveys. Having data processed, archived and published by dedicated teams leaves other scientists free to concentrate on using the data, and is a very cost-effective way to do astronomy."

Im Focus: Light from a roll – hybrid OLED creates innovative and functional luminous surfaces

Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.

The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...

Im Focus: Regensburg physicists watch electron transfer in a single molecule

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
