Submission + - Astronomers detect and 'weigh' very young solar system

ogre7299 writes: Astronomers have found direct evidence of a forming proto-solar system and 'weighed' the forming star for the first time as repored in a recent Nature paper paywalled arXiv version and highlighted on space.com
Beneath a dusty disk of creation, a baby star's mass has been measured for the first time. The star, called L1527 IRS, is only one-fifth the mass of the sun, and is expected to keep growing as the swirling disk of matter surrounding it falls into its surface. Astronomers estimated the star formed around the same time that Neanderthals evolved on Earth: just 300,000 years ago.

Submission + - Herschel-HIFI Unveils Precursors of Life in Orion (caltech.edu)

ogre7299 writes: ""The Herschel Space Observatory has revealed the chemical fingerprints of potential life-enabling organic molecules in the Orion Nebula, a nearby stellar nursery in our Milky Way galaxy. The European Space Agency leads the Herschel mission with important participation from NASA. This detailed-spectrum, obtained with the Heterodyne Instrument for the Far Infrared (HIFI) — one of Herschel's three innovative instruments — demonstrates the gold mine of information that Herschel-HIFI will provide on how organic molecules form in space.
The spectrum, one of the first to be obtained with HIFI since it returned to full health in January 2010 following technical difficulties, clearly demonstrates that the instrument is working well."

"[The HIFI instrument has previously been offline since] August 2009 when HIFI experienced an unexpected voltage spike in the electronic system, probably caused by a high-energy cosmic particle, resulting in the instrument shutting down. On 14 January 2010, HIFI was successfully switched back on using its spare electronics with science observations commencing on 28 February.""
