Herschel reveals the hidden side of star birth

The first scientific results from ESA's Herschel infrared space observatory are revealing previously hidden details of star formation. New images show thousands of distant galaxies furiously building stars and beautiful star-forming clouds draped across the Milky Way. One picture even catches an 'impossible' star in the act of formation.

Press invitation to the Herschel First Results Media Day

Media representatives are cordially invited to celebrate the release of the first results from ESAs Herschel infrared space telescope. The theme of the media day is: Revealing the Hidden Side of Star Formation.
The event will take place at Space Expo, at the European Space Research and Technology Centre (ESTEC), Noordwijk, The Netherlands on 6 May. Doors open at 11:30 am. The media day is organised in connection with the Herschel First Results Symposium at ESTEC.

It takes special software to map the universe from noisy data. Berkeley Lab scientists developed a code called MADmap to do just that for the cosmic microwave background, then posted it on the web for other interested sky mappers. Scientists probing the sky with the PACS instrument aboard the Herschel satellite have adapted MADmap to make spectacular images of the infrared universe.

To map our home planet, Google Earth depends mostly on satellite imagery for land surfaces and sonar imagery for the sea floor. Maps of the Universe likewise depend on different kinds of detectors for different kinds of features. Maps of the cosmic microwave background (CMB), for example, depend on measuring minute differences in the temperature of the sky.
When astrophysicist Julian Borrill came to Berkeley Lab's National Energy Research Scientific Computing Centre (NERSC) in 1997, his first project was designing computational tools for future CMB experiments, a toolbox capable of handling an expected flood of cosmic data. He and his colleagues Radek Stompor and Andrew Jaffe devised the Microwave Anisotropy Dataset Computational Analysis Package, or MADCAP. An essential part of the kit was a module for making maps.

Herschel readies itself for the Orion Nebula

ESA's Herschel observatory is back to full operation following the reactivation of its HiFi instrument. HiFi, having been offline for 160 days while engineers investigated an unexpected problem in the electronic system, is now perfectly placed to resume its study of forming stars and planets.
HiFi, the Heterodyne Instrument for the Far Infrared, was built specifically to observe water in a variety of celestial objects. Its first observation, on 22 June 2009, showed that it was performing beyond its design specification. However, by 3 August 2009, something was clearly wrong and the instrument team and ESA had to decide what to do.

Europe's billion-euro Herschel Space Telescope is fully operational again after engineers brought its damaged instrument back online.
The observatory's HiFi spectrometer was turned off just three months into the mission because of an anomaly that was probably triggered by space radiation.

Initial results from the Herschel science demonstration phase have been presented by and to the scientific community at a recent workshop. Both SPIRE and PACS instruments have been tested to their full capabilities and have passed the tests with flying colours. Initial science results include the first image of a previously hidden region of star formation, observations of one of the coldest objects in the Solar System, and new perspectives on the highly energetic processes in the environments of newborn stars.

The European Space Agency (Esa) has released stunning new pictures from the recently launched Herschel telescope.
The pictures show star formation, and have been described as among the most important images obtained from space for decades.
Astronomers hope that, by analysing these images, they will be able to answer questions about how stars and galaxies are made.
Herschel is the largest astronomical telescope ever to be put into space.

Data from outer space opens new frontiers for researchers
The latest data delivered back to Earth by the Herschel Space Observatory (HSO) - launched in May by the European Space Agency - has opened a new window on galaxies for researchers at McMaster University.
Herschel, the largest infrared telescope ever launched, is designed to study some of the coldest objects in space, located deep in a region of the electromagnetic spectrum that is still largely unexplored.

The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 510 square degrees of the extragalactic sky, four times larger than all the other Herschel surveys combined, in five far-infrared and submillimetre bands. We describe the survey, the complementary multi-wavelength datasets that will be combined with the Herschel data, and the six major science programmes we are undertaking. Using new models based on a previous submillimetre survey of galaxies, we present predictions of the properties of the ATLAS sources in other wavebands.
