Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond our Milky Way Galaxy. FRB emission characteristics favor magnetars as their sources, as evidenced by FRB-like bursts from a magnetar in the Milky Way, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown.
Scientists Discover Impenetrable Barrier 11,500 km above Earth
Nov 27, 2014 · Next ». A group of researchers headed by Prof Daniel Baker of the University of Colorado’s Laboratory for Atmospheric and Space Physics has discovered a nearly impenetrable barrier some 11,500 km above our planet that blocks so-called ‘killer electrons,’ which can fry satellites and degrade space systems during intense solar storms.

Apr 10, 2024 · Sep 11, 2024 by Sergio Prostak. Chemists at the Leibniz Institute for Tropospheric Research have provided experimental evidence that sulfurous acid (H2SO3), once formed in the gas phase, is kinetically stable enough to allow its characterization and subsequent reactions. In the gas phase, if once formed, sulfurous acid shows a certain kinetic ...
