| Orion's Hidden Fiery Ribbon. A dramatic new image of cosmic clouds in the constellation of Orion reveals what seems to be a fiery ribbon in the sky. This orange glow represents faint light coming from grains of cold interstellar dust, at wavelengths too long for human eyes to see. It was observed by the ESO-operated Atacama Pathfinder Experiment (APEX) in Chile. |
|
| The APEX water vapour radiometer is back into operations. PWV data is available from the APEX weather page. |
|
| Edouard Gonzalez has joined the APEX team as telescope and instruments operator. Welcome to APEX Edouard !!! |
|
| Setting the Dark on Fire. A new ESO photo release from the Atacama Pathfinder Experiment (APEX) telescope in Chile shows a beautiful view of clouds of cosmic dust in the region of Orion. While these dense interstellar clouds seem dark and obscured in visible-light observations, APEX's LABOCA camera can detect the heat glow of the dust and reveal the hiding places where new stars are being formed. But one of these dark clouds is not what it seems. |

| APEX's Icy Companions featured in the ESO Picture of the week. |
|
| OTF (On-The-Fly) Observing time calculator released and available here. |
|
| We have started to transfer the APEX data to the Archive in Garching via network. This drastically reduces the time between observations being made and data delivery to the PIs. For more information, check this poster presented by F. Montenegro at the APEX Ringberg meeting. |

APEX takes part in sharpest observation ever - Telescopes in Chile, Hawaii, and Arizona reach sharpness two million times finer than human vision. An international team of astronomers has observed the heart of a distant quasar with unprecedented sharpness, two million times finer than human vision. The observations, made by connecting the Atacama Pathfinder Experiment (APEX) telescope to two others on different continents for the first time, is a crucial step towards the dramatic scientific goal of the Event Horizon Telescope project: Imaging the supermassive black holes at the centre of our own galaxy and others.

A new image of the region surrounding the reflection nebula Messier 78, just to the north of Orion's Belt, shows clouds of cosmic
dust threaded through the nebula like a string of pearls. The observations, made with the Atacama Pathfinder Experiment (APEX) telescope,
use the heat glow of interstellar dust grains to show astronomers where new stars are being formed. More info at ESO Photo release 1219 |

ESO Science Release eso1209 - APEX Turns its Eye to Dark Clouds in Taurus. A new image from the APEX (Atacama Pathfinder Experiment) telescope in Chile shows a sinuous filament of cosmic dust more than ten light-years long. In it, newborn stars are hidden, and dense clouds of gas are on the verge of collapsing to form yet more stars. It is one of the regions of star formation closest to us. The cosmic dust grains are so cold that observations at wavelengths of around one millimetre, such as these made with the LABOCA camera on APEX, are needed to detect their faint glow.

ESO Science Release eso1206 - The Wild Early Lives of Today's Most Massive Galaxies - Dramatic star formation cut short by black holes. Using the APEX telescope, a team of astronomers has found the strongest link so far between the most powerful bursts of star formation in the early Universe, and the most massive galaxies found today. The galaxies, flowering with dramatic starbursts in the early Universe, saw the birth of new stars abruptly cut short, leaving them as massive --- but passive --- galaxies of aging stars in the present day. The astronomers also have a likely culprit for the sudden end to the starbursts: the emergence of supermassive black holes. More info at ESO Science release 1206 |

ESO Science Release eso1123 - Hydrogen Peroxide Found in Space.
Molecules of hydrogen peroxide have been found for the first time in interstellar space.
The discovery gives clues about the chemical link between two molecules critical for life:
water and oxygen. On Earth, hydrogen peroxide plays a key role in the chemistry of water and
ozone in our planet atmosphere, and is familiar for its use as a disinfectant or to bleach
hair blonde.
Now it has been detected in space by astronomers using the ESO-operated APEX telescope in Chile.

ESO Science Release eso1012 - APEX Snaps First Close-up of Star Factories in Distant Universe.For the first time, astronomers have made direct
measurements of the size and brightness of regions of star-birth in a very distant galaxy, thanks to a chance discovery with the APEX telescope.
The galaxy is so distant, and its light has taken so long to reach us, that we see it as it was 10 billion years ago. A cosmic gravitational lens
is magnifying the galaxy, giving us a close-up view that would otherwise be impossible. This lucky break reveals a hectic and vigorous star-forming
life for galaxies in the early Universe, with stellar nurseries forming one hundred times faster than in more recent galaxies.
