... A Powerful Gamma Ray Burst . ... Credit Copyright: S. R. Kulkarni, S. G. Djorgovski ( Caltech ), the Caltech GRB Team , NASA Explanation: Gamma-ray bursts are thought to be the most powerful explosions in the Universe, yet the cause of these high-energy flashes remains a mystery . Blindingly bright for space-based gamma-ray detectors the burst sources are so faint at visible wavelengths that large telescopes and sensitive cameras are required to search for them. ... Gamma Ray Bursting . ...

Estimates for the Set-theoretic Distance between Orbits of Celestial Bodies . ... It is reasonable to use preliminary simple criteria for the proximity to intersection based on estimates of set-theoretic distance ( , 0 ) between orbits , 0 of celestial bodies , 0 . ... We describe here two simple criteria and one more complicated one. ... The third one requires calculation of the distance itself and it amounts to solving a trigonometric equation of the 8-th degree. ...
