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...
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...
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 ...
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...
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...
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...
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.
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...
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 ...
