The NASA catches an enormous stellar explosion
The Swift satellite of the Basket caught in March a powerful emanation originating gamma ray of the explosion of a distant star whose exceptional light intensity was perceivable at first, indicated east Wednesday the American space agency.
This observation of the Swift gave to the astronauts the most detailed images until today of a cosmic event like this, that also was captured by other satellites and earth telescopes. Swift detected the explosion of the star to 7,500 million years light, in the constellation of Bouvier to 06H13 GMT of the 19 of March. Emanation gamma the ray was almost directly oriented towards the Earth.
Swift is known to detect explosions exceptionally powerful gamma ray and with this explosion really we have captured a great amount , explained astronomer Neil Gehrels, of the Center of Space Flights Goddard of the Basket in Maryland (this), main scientist of the mission.
An explosion of this intensity in the direction of the Earth is a rare event that every decade takes place approximately once, according to the astronomers who officially called GRB 080319B.
In a study that will appear in the last edition of the British magazine Nature Thursday, astronomer Judith Racusin of the University of Pensilvania (this) and an equipment of 92 investigators describe all the observations of Swift initiated 30 minutes before the explosion of the star and during the following months to study their effects.
The scientists concluded that the extraordinary luminosity was been from an emanation of stellar materials projected directly towards the Earth almost at the speed of the light.
