Geology of the Icy Satellites
In the last 25 years, the explorations of the Voyager and Galileo missions have resulted in an entirely new view of the icy worlds orbiting the giant outer planets. These objects show a huge diversity in their characteristics, resulting from their formation histories, internal processes and interactions with their space environments. This paper will review the current state of knowledge about t...
متن کاملBlasts from the past.
With this issue of the JCI, we celebrate the 80th anniversary of the Journal. While 80 years is not a century, we still feel it is important to honor what the JCI has meant to the biomedical research community for 8 decades. To illustrate why the JCI is the leading general-interest translational research journal edited by and for biomedical researchers, we have asked former JCI editors-in-chief...
متن کاملMicrobial Habitability of Icy Worlds
F or most of Earth’s history, life was microscopic and, even today, microorganisms dominate the planet. Hence, we believe that, if life exists beyond Earth, it likely started as microorganisms and may remain at this stage. Much of contemporary astrobiological research focuses on the metabolic potential of microorganisms and their ability to inhabit extreme environments. The search for life beyo...
متن کاملStudy of Anomalous Mine Blasts
The Altai-Sayan mining region located east of Novosibirsk, Russia, comprises over 72 mines which are located between 7 and 559 km from the International Monitoring System (IMS) primary 3-component station ZAL. We have origin time and location estimates of 853 blasts that have occurred in this trend between 1/1/1995 and 6/30/2000. The mines are known to use millisecond delay-fire blasting and ha...
متن کاملThe icy side of Frosty Leo
An imaging study of the bipolar nebula Frosty Leo is presented. In particular, we have studied the effects of spatial distribution of H2O ice on the circumstellar environment. Using the Keck telescope with the NIRC infrared camera, we have recovered images at a wavelength of 3.08 μm within the prominent (attenuation of about 5 mag) water-ice absorption band, and in the adjacent quasi-continuum ...
