An international team of scientists has found a way to recover the birth places of stars in our Galaxy. This is one of the major goals in the field of Galactic Archaeology, whose aim is to reconstruct the formation history of the Milky Way.
As large stars explode, their interiors collapse down to a point at which all of their particles become neutrons. If the newly born star has a magnetic field and rotates fast enough, it can accelerate nearby charged particles and become what astronomers call a pulsar wind nebula.
An international team of researchers has proposed a new method to investigate the inner workings of supernovae explosions. This new method uses meteorites and is unique in that it can determine the contribution from electron anti-neutrinos, enigmatic particles which can't be tracked through other means.
Researchers show how Jupiter was formed. Data collected from meteorites had indicated that the growth of the giant planet had been delayed for two million years. Now the researchers have found an explanation: Collisions with kilometer-sized blocks generated high energy, which meant that in this phase hardly any accretion of gas could take place and the planet could only grow slowly.
