The second of three images of ESO's GigaGalaxy Zoom project has just been released online. It is a new and wonderful 340-million-pixel vista of the central parts of our home galaxy as seen from ESO's Paranal Observatory with an amateur telescope. This 34 by 20-degree wide image provides us with a view as experienced by amateur astronomers around the world. However, its incredible beauty and appeal owe much to the quality of the observing site and the skills of St©phane Guisard, the...

Thanks to a unique "ballistic study" that combines data from ESO's Very Large Telescope and NASA's Chandra X-ray Observatory, astronomers have now solved a long-standing mystery of the Milky Way's particle accelerators. They show in a paper published today on Science Express that cosmic rays from our galaxy are very efficiently accelerated in the remnants of exploded stars. During the Apollo flights astronauts reported seeing odd flashes of light, visible even with their eyes closed. We have...

The next generation of instruments for ground-based telescopes took a leap forward with the development of a new ultra-fast camera that can take 1500 finely exposed images per second even when observing extremely faint objects. The first 240x240 pixel images with the world's fastest high precision faint light camera were obtained through a collaborative effort between ESO and three French laboratories from the French Centre National de la Recherche Scientifique/Institut National des Sciences...

Europe's billion dollar Herschel space observatory has accomplished a huge milestone by opening the hatch that has been sheltering its susceptible instruments from contamination. This allowed the light gathered by Herschel's massive mirror to flood the chilled instrument chamber, or cryostat, for the very first time. The observatory's goal is to learn how stars and galaxies are created, and how they develop. The command to release two pyrotechnic bolts attached to the hatch was the biggest...

ESO's Very Large Telescope "” Europe's flagship facility for ground-based astronomy "” has been equipped with the first of its second generation instruments: X-shooter. It can record the entire spectrum of a celestial object in one shot "” from the ultraviolet to the near-infrared "” with high sensitivity. This unique new instrument will be particularly useful for the study of distant exploding objects called gamma-ray bursts. "X-shooter offers a capability that is...

Scientists and engineers working on the world's largest ground-based astronomical project, the Atacama Large Millimeter/submillimeter Array (ALMA), have achieved another milestone "” the successful linking of two ALMA astronomical antennas, synchronized with a precision of one millionth of a millionth of a second "” to observe the planet Mars. ALMA is under construction by an international partnership in the Chilean Andes. On 30 April, the team observed the first "interferometric...

Astronomers with the e-Merlin system of telescopes have seen "Ëœfirst light' as they look forward to being able to see further and more clearly than ever before. "The new optical fiber network, together with new electronics at each telescope and a powerful new "Ëœcorrelator' which combines the signals at Jodrell Bank, will make the telescope one of the most powerful of its type in the world," said Professor Simon Garrington, Director of e-Merlin. "The e-Merlin fiber...

Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...
