Protostar displays a strange geometry

Using observations of molecules in the protostar L1527 taken by the ALMA observatory in northern Chile, a group of researchers has uncovered new clues to understanding how dust in a collapsing molecular cloud can shed angular momentum and penetrate beyond an area known as the ‘centrifugal barrier’ to find its way to the surface of the forming star. …

Ultrasmall atom motions recorded with ultrashort x-ray pulses

Periodic motions of atoms over a length of a billionth of a millionth of a meter are mapped by ultrashort x-ray pulses. In a novel type of experiment, regularly arranged atoms in a crystal are set into vibration by a laser pulse and a sequence of snapshots is generated via changes of x-ray absorption.
