Scientists ancient lakebed deep beneath Greenland ice
2020/11/20
Scientists have detected what they say are the sediments of a huge ancient lakebed sealed more than a mile beneath the ice of northwest Greenland -- the first-ever discovery of such a sub-glacial feat...
Europa’s heaving ice might make more heat than scientists thought
Europa ice heat scientists
2016/4/25
Jupiter’s moon Europa is under a constant gravitational assault. As it orbits, Europa’s icy surface heaves and falls with the pull of Jupiter’s gravity, creating enough heat, scientists think, to supp...
Interactive evolution of multiple water-ice reservoirs on Mars: Insights from hydrogen isotope compositions
Mars water ice isotope atmospheric escape
2017/4/10
Remote sensing data from orbiter missions have proposed that ground ice may currently exist on Mars, although the
volume is still uncertain. Recent analyses of Martian meteorites have suggested that ...
The Spitzer ice legacy: Ice evolution from cores to protostars
Spitzer ice legacy Ice evolution cores protostars
2011/10/20
Ices regulate much of the chemistry during star formation and account for up to 80% of the available oxygen and carbon. In this paper, we use the Spitzer c2d ice survey, complimented with data sets on...
Ice chemistry in massive Young Stellar Objects: the role of metallicity
astrochemistry – circumstellar matter – galaxies individual (LMC, SMC) –Magellanic Clouds – stars formation – stars: protostars
2010/11/15
We present the comparison of the three most important ice constituents (water, CO and CO2)
in the envelopes of massive Young Stellar Objects (YSOs), in environments of differentmetallicities:the Gala...
Ross Ice Shelf in situ radio-frequency ice attenuation
Ross Ice Shelf situ radio-frequency ice attenuation
2010/11/10
We have measured the in situ average electric field attenuation length hL i for radio frequency signals broadcast vertically through the Ross Ice Shelf. We chose a location,Moore Embayment, south of M...
Research and calibration of Acoustic Sensors in ice within the SPATS (South Pole Acoustic Test Setup) project
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/29
We present development work aiming towards a large scale ice-based hybrid detector including acoustic sensors for the detection of neutrinos in the GZK range.
Integrating GPR and CCRI techniques：Implications for the identification and mapping of ground ice on Mars
ground ice identification and mapping Mars
2009/6/1
Our results show that GPR and CCRI techniques effectively complement each other by resolving different characteristics of the subsurface. While GPR clearly showed the subsurface structures and interfa...
HOW MANY UNIVERSES ARE NECESSARY FOR AN ICE CREAM TO MELT?
cosmology theory-gravitation-history and philosophy of astronomy
2009/3/13
We investigate a quantitative consequence of the Acausal-Anthropic
approach to solving the long-standing puzzle of the thermodynamical arrow
of time. Notably, the size of the required multiverse is ...
