Une première image du trou noir au centre de notre galaxie?
C’est grâce à un réseau mondial de radiotélescopes qu’une équipe internationale d’astronomes essaiera en avril, une première dans l’histoire de l’astronomie, d’obtenir une image du centre de notre galaxie, là où se trouve un trou noir géant. Ce projet mondial s’appelle Event Horizon Telescope (EHT) et associe des télescopes du monde entier – de l’Europe jusqu’au pôle sud, en passant par le Chili et Hawaii. Le télescope de 30-mètres de l'IRAM est la seule station d'observation en Europe...

Imaging the black hole at the center of our Galaxy
An international team of astronomers will join in April and try for the first time in the history of astronomy, to capture an image of the center of our galaxy, where a giant black hole lies. This worldwide project is called Event Horizon Telescope (EHT); it combines telescopes across four continents from Europe to the South Pole, through Chile and Hawaii. The IRAM 30-meter telescope is one of them...

Beyond the appearances: The anatomy of the Orion Jedi revealed by radio-astronomy
Using the IRAM 30-meter radio-telescope, an international team of astronomers has obtained the most comprehensive radio-survey of the Orion B star-forming region, famous for hosting the iconic Horsehead and Flame nebulae. Through a careful dissection of the cloud into regions of different molecular composition, they shed new light on how the darkest and coldest inner parts give birth to new stars. Following mankind's tradition of associating characters with features on the sky, the radio astronomy view of Orion B seems to show the skeleton of a fighting Star Wars Jedi!

IRAM reveals phosphorus molecular compounds in the solar-type star-forming region L1157
The IRAM 30-meter radiotelescope was used to lead a systematic search for molecules containing phosphorus (P) towards L1157-B1, a shock wave front created by the propagation of a supersonic jet emanating from a solar-type protostar. Several spectral lines of phosphorus mononitride (PN) were detected and, for the first time in a solar-type star-forming region, the lines of phosphorus monoxyde (PO), a molecule of high biological interest.

NIKA captures the merging of galaxy clusters
A team of researchers from the NIKA consortium has obtained for the first time an image of the gas velocity in a merging cluster of galaxies. These observations open a new way to study the formation of the largest structures in the Universe, formed through the most energetic events since the Big Bang.
