(Picture: Esa / Nasa-JPL / Caltech / UCL / STScI) ESAĺs Herschel space observatory has discovered that titanic stellar explosions can be excellent dust factories. In space, the dust mixes with gas to become the raw material for new stars, planets and, ultimately, life. This discovery may solve a mystery of the early Universe. M.

The Scientific Organizing Committee of the 2010 NASA Laboratory
Astrophysics Workshop has released the White Paper that it was charged to produce by NASA. It is available from arXiv [here].
As set out in the Workshop Charter, the purpose of the meeting was "to
provide a forum within which the scientific community can review the
current state of knowledge in the field of Laboratory Astrophysics,
assess the critical data needs of NASA's current and future Space
Astrophysics missions, and identify the challenges and opportunities
facing the field as we begin a new decade," and the White Paper presents
the Scientific Organizing Committee's synthesis and summary of those
activities along with certain key findings.

Tunneling effects in the reaction between hydrogen atoms and benzene have been studied with a new direct dynamics implementation of harmonic quantum transition-state theory. In certain regions of interstellar space, tunneling could facilitate H chemisorption on polycyclic aromatic hydrocarbons, thereby catalyzing HD and H2 formation.

"Detection of C60 and C70 in a Young Planetary Nebula",
Abstract: In the last decades, a number of molecules and diverse dust features have been identified by astronomical observations in various environments. Most of the dust that determines the physical and chemical characteristics of the interstellar medium (ISM) is formed in the outflows of asymptotic giant branch (AGB) stars and is further processed when these objects become planetary nebulae (PNe). Here, we report on the environment of Tc 1, a peculiar PN whose infrared spectrum shows emission from cold and neutral C60 and C70. The two molecules amount to a few percent of the available cosmic carbon in this region, showing that if the conditions are right, fullerenes can and do form efficiently in space.

- (July 11, 2010, by Xander Tielens) The refereeing process for the HIFI First Result special issue of A & A will conclude on July 31, 2010. As of this writing, a large number of papers have already been accepted and are available through Astroph. Together, these papers give a good impression of the versatility of HIFI and the expected breadth of HIFI's impact on astrophysics and astrochemistry. We want to alert you to the website, http://hifi.strw.leidenuniv.nl/, where we collect these papers and provide relevant links to the teams webpages. As a service to the community, we will add HIFI papers, as they are accepted for publication, to this page throughout the mission. So, you might want to bookmark this page as an easy entry point for HIFI results. In addition, we hope that these papers may inspire you to submit a proposal in response to the Herschel Open Time Announcement of Opportunity using HIFI (http://herschel.esac.esa.int/AO_Introduction.shtml), which are due on July 22nd, 2010.
