Uncovering the birthplaces of stars in the Milky Way

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.

Astronomers witness birth of new star from stellar explosion

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.

Falling stars hold clue for understanding dying stars

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.

Jupiter had growth disorders

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.

Million fold increase in the power of waves near Jupiter's moon Ganymede

Listening to electro-magnetic waves around the Earth, converted to sound, is almost like listening to singing and chirping birds at dawn with a crackling camp fire nearby. This is why such waves are called chorus waves. They cause polar lights but also high-energy 'killer' electrons that can damage spacecraft. In a recent study, the authors describe extraordinary chorus waves around other planets in our solar system.
