This giant cloud of gas and dust is creating intensely bright young stars, and is home to young stellar clusters. This image is a tiny part of just one of eleven public surveys of the sky now in progress using ESO telescopes. Together these are providing a vast legacy of publicly available data for the global astronomical community.
VST images the Lagoon Nebula
PR Image eso1403a
The Lagoon Nebula is an intriguing object located around 5000 light-years from us in the constellation of Sagittarius (The Archer). Also known as Messier 8, it is a giant cloud 100 light-years across, where new stars are forming within its plumes of gas and dust .
This new 16 000-pixel-wide image is from the VLT Survey Telescope (VST), one of two dedicated survey telescopes at ESO's Paranal Observatory in northern Chile. A zoomable version of the image allows the viewers to explore the many nooks and crannies of this fascinating object.
The VST was not pointed at the Lagoon deliberately, it simply was included as part of a huge imaging survey called VPHAS+ that covered a much larger region of the Milky Way. VPHAS+ is just one of three imaging surveys using visible light with the VST. These are complemented by six infrared surveys with the VISTA survey telescope.
The surveys are addressing many important questions in modern astronomy. These include the nature of dark energy, searching for brilliant quasars in the early Universe, probing the structure of the Milky Way and looking for unusual and hidden objects, studying the neighbouring Magellanic Clouds in great detail, and many other topics. History shows that surveys often find things that are unexpected and these surprises are crucial for the progress of astronomical research.
As well as the nine imaging surveys with VISTA and the VST there are also two additional surveys that are in progress using other ESO telescopes. One, the Gaia-ESO Survey, is using the Very Large Telescope at Paranal to map the properties of more than 100 000 stars in the Milky Way, and another (PESSTO) is following up on transient objects such as supernovae using the New Technology Telescope at La Silla .
Some of these surveys began back in 2010, and some much more recently, but data from all of them are now being made public and are accessible to astronomers around the world through ESO's archive .
Although they are still in progress, the surveys are already allowing astronomers to make many discoveries. Just a few of these new results include new star clusters found in the VVV survey (eso1128, eso1141), the best map yet of the central parts of our Milky Way (eso1242, eso1339), a very deep view of the infrared sky (eso1213) and, very recently, some of the most distant quasars discovered so far (from the VISTA VIKING survey).
The ESO Public Surveys will continue for many years, and their astronomical legacy value will stretch many decades into the future.Notes
 More information about all eleven surveys are available here and a comprehensive description of their current status and results is given in a dedicated section of the latest ESO Messenger.

Subaru Telescope helps pinpoint origin of ultra-high energy neutrino

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
