A model to predict gamma ray burst (GRB) behaviour, developed by a team headed by University of Johannesburg Centre for Astro-Particle Physics director Prof. Soebur Razzaque, has been strongly supported by observational data. The data came from observations of a GRB detected on April 15 last year and the results of the analysis of this data were released in this month’s edition of Nature Astronomy. The burst was detected by five gamma ray detectors. Three of these were in Earth orbit, one was at the L1 libration point between the Earth and the Sun and one was on the Mars Odyssey spacecraft, orbiting the Red Planet. (Libration points are also known as Lagrange points; at these points a small mass, such as a spacecraft, can orbit in a constant pattern with the two large masses whose gravitational interaction creates the Lagrange point.)
