To collect enough gamma rays to diagnose what is happening inside a cosmic particle accelerator, one needs to point the telescopes at this source for many hours; in extreme cases, data for one celestial object may be accumulated for several hundred hours.

How can a scientist tell these organisms apart when they are so small? One way is the bacteria's characteristic shape or pattern of joining toget ...

As a result we are only interested in calculating the specific intensity at frequencies capable of ionizing HI, HeI, and HeII ...

EXPOSE



EXPOSE is a multi-user facility mounted outside the International Space Station dedicated to astrobiology. EXPOSE was developed by the European Space Agency (ESA) for long-term spaceflights and was designed to allow exposure of chemical and biological samples to outer space while recording data during exposure.The results will contribute to our understanding of photobiological processes in simulated radiation climates of planets (e.g. early Earth, early and present Mars, and the role of the ozone layer in protecting the biosphere from harmful UV-B radiation), as well as studies of the probabilities and limitations for life to be distributed beyond its planet of origin. EXPOSE data support long-term in situ studies of microbes in artificial meteorites, as well as of microbial communities from special ecological niches. Some EXPOSE experiments investigated to what extent particular terrestrial organisms are able to cope with extraterrestrial environmental conditions. Others tested how organic molecules react when subjected for a prolonged period of time to unfiltered solar light.
