Jan 9, 2018 by News Staff

An international team of scientists led by Professor Hanns-Christian Gunga of Charité-Universitätsmedizin Berlin has observed that astronauts run hot when exposed to weightlessness, and that, even at rest, their core body temperature is around one degree Celsius above the normal value. The results appear in the journal Scientific Reports. Stahn et al observed for the first time a sustained increased astronauts’ core body temperature under resting...

This image from the NASA/ESA Hubble Space Telescope shows ACT-CLJ0102-4915. Massive galaxy clusters such as ACT-CLJ0102-4915 are useful tools for studying very distant objects, because this lens-like behavior amplifies the light from faraway galaxies in the background. They also contribute to a range of topics in cosmology, as the precise nature of the lensed images encapsulates information about the properties of spacetime, the expansion of the cosmos and the distribution of dark matter within the cluster.
