"Observations of Active Region Loops with the EUV Imaging Spectrometer on Hinode
ABSTRACT
Previous solar observations have shown that coronal loops near 1 MK are difficult to reconcile with simple heating models. These loops have lifetimes that are long relative to a radiative cooling time, suggesting quasi-steady heating. The electron densities in these loops, however, are too high to be consistent with thermodynamic equilibrium. Models proposed to explain these properties generally rely on the existence of smaller scale filaments within the loop that are in various stages of heating and cooling. Such a framework implies that there should be a distribution of temperatures within a coronal loop. In this paper we analyze new observations from the EUV Imaging Spectrometer (EIS) on Hinode. EIS is capable of observing active regions over a wide range of temperatures (Fe viii–Fe xvii) at relatively high spatial resolution (1 ). We find that most isolated coronal loops that are bright in Fe xii generally have very narrow temperature distributions ( K), but are not isothermal. We also derive volumetric filling factors in these loops of approximately 10%. Both results lend support to the filament models." The Astrophysical Journal Letters

AKARI Near-Infrared Spectroscopy: Detection of H2O and CO2 Ices toward Young Stellar Objects in the Large Magellanic Cloud
ABSTRACT
We present the first results of AKARI Infrared Camera near-infrared spectroscopic survey of the Large Magellanic Cloud (LMC). We detected absorption features of the H2O ice 3.05 μm and the CO2 ice 4.27 μm stretching mode toward seven massive young stellar objects (YSOs). These samples are for the first time spectroscopically confirmed to be YSOs. We used a curve-of-growth method to evaluate the column densities of the ices and derived the CO2/H2O ratio to be 0.45 ± 0.17. This is clearly higher than that seen in Galactic massive YSOs (0.17 ± 0.03). We suggest that the strong ultraviolet radiation field and/or the high dust temperature in the LMC may be responsible for the observed high CO2 ice abundance.

Hinode
"Observations of Active Region Loops with the EUV Imaging Spectrometer on Hinode
ABSTRACT
Previous solar observations have shown that coronal loops near 1 MK are difficult to reconcile with simple heating models. These loops have lifetimes that are long relative to a radiative cooling time, suggesting quasi-steady heating. The electron densities in these loops, however, are too high to be consistent with thermodynamic equilibrium. Models proposed to explain these properties generally rely on the existence of smaller scale filaments within the loop that are in various stages of heating and cooling. Such a framework implies that there should be a distribution of temperatures within a coronal loop. In this paper we analyze new observations from the EUV Imaging Spectrometer (EIS) on Hinode. EIS is capable of observing active regions over a wide range of temperatures (Fe viii–Fe xvii) at relatively high spatial resolution (1 ). We find that most isolated coronal loops that are bright in Fe xii generally have very narrow temperature distributions ( K), but are not isothermal. We also derive volumetric filling factors in these loops of approximately 10%. Both results lend support to the filament models." The Astrophysical Journal Letters

AKARI
AKARI Near-Infrared Spectroscopy: Detection of H2O and CO2 Ices toward Young Stellar Objects in the Large Magellanic Cloud
ABSTRACT
We present the first results of AKARI Infrared Camera near-infrared spectroscopic survey of the Large Magellanic Cloud (LMC). We detected absorption features of the H2O ice 3.05 μm and the CO2 ice 4.27 μm stretching mode toward seven massive young stellar objects (YSOs). These samples are for the first time spectroscopically confirmed to be YSOs. We used a curve-of-growth method to evaluate the column densities of the ices and derived the CO2/H2O ratio to be 0.45 ± 0.17. This is clearly higher than that seen in Galactic massive YSOs (0.17 ± 0.03). We suggest that the strong ultraviolet radiation field and/or the high dust temperature in the LMC may be responsible for the observed high CO2 ice abundance.

Hinode
"Observations of Active Region Loops with the EUV Imaging Spectrometer on Hinode
ABSTRACT
Previous solar observations have shown that coronal loops near 1 MK are difficult to reconcile with simple heating models. These loops have lifetimes that are long relative to a radiative cooling time, suggesting quasi-steady heating. The electron densities in these loops, however, are too high to be consistent with thermodynamic equilibrium. Models proposed to explain these properties generally rely on the existence of smaller scale filaments within the loop that are in various stages of heating and cooling. Such a framework implies that there should be a distribution of temperatures within a coronal loop. In this paper we analyze new observations from the EUV Imaging Spectrometer (EIS) on Hinode. EIS is capable of observing active regions over a wide range of temperatures (Fe viii–Fe xvii) at relatively high spatial resolution (1 ). We find that most isolated coronal loops that are bright in Fe xii generally have very narrow temperature distributions ( K), but are not isothermal. We also derive volumetric filling factors in these loops of approximately 10%. Both results lend support to the filament models." The Astrophysical Journal Letters

AKARI Near-Infrared Spectroscopy: Detection of H2O and CO2 Ices toward Young Stellar Objects in the Large Magellanic Cloud
ABSTRACT
We present the first results of AKARI Infrared Camera near-infrared spectroscopic survey of the Large Magellanic Cloud (LMC). We detected absorption features of the H2O ice 3.05 μm and the CO2 ice 4.27 μm stretching mode toward seven massive young stellar objects (YSOs). These samples are for the first time spectroscopically confirmed to be YSOs. We used a curve-of-growth method to evaluate the column densities of the ices and derived the CO2/H2O ratio to be 0.45 ± 0.17. This is clearly higher than that seen in Galactic massive YSOs (0.17 ± 0.03). We suggest that the strong ultraviolet radiation field and/or the high dust temperature in the LMC may be responsible for the observed high CO2 ice abundance.

Water Hit with Young Star's Best Shot "Sep 18, 2008
Water is being blasted to pieces by a young star's laser-like jets, according to new observations from NASA's Spitzer Space Telescope.
The discovery provides a better understanding of how water -- an essential ingredient for life as we know it -- is processed in emerging solar systems."

GRB 070610: associated with high-energy star deaths.
"The initial burst of GRB 070610 came with a "bizarre X-ray counterpart," and within a minute, researchers began collecting data on this in various other wavelengths.
Renamed SWIFT J195509+1261406, the event went quiet over the next few days until a single near-IR flare was observed by the ESO's Very Large Telescope. Almost six months later, no further bursts were measured by the XMM-Newton spacecraft. "

Mapping the universe at 30 Terabytes a night • The Register
"The Large Synoptic Survey Telescope (LSST)
When it's fully operational in 2016: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects
In its planned 10-year run, the LSST will capture, process and store more than 30 Terabytes (TB) of image data each night, yielding a 150 Petabytes (PB) database. Talking to The Reg, Kantor called this the largest non-proprietary dataset in the world.
The data reduction pipelines are developed in C++ and Python. They rely on approximately 30 off-the-shelf middleware packages/libraries for parallel processing, data persistence and retrieval, data transfer, visualization, operations management and control, and security. The current design is based on MySQL layered on a parallel, fault-tolerant file system."
