Clues to the Reionization Mystery of the Universe
How did the universe go from being neutral and opaque to transparent and reionized at z ~ 6? Today’s paper gives us some observational evidence for what might be responsible.

Observations of dwarf galaxies show that sites of active star formation have fewer metals. These galaxies may have been diluted by the impact of pristine gas from the cosmic web.
The Hyades underpins our understanding of stellar ages. If its age is wrong then a lot of other ages are wrong too…
Magnetic fields are a crucial part of star formation. Read on whether and how the magnetic field strength dissipates during the early collapsing phase.
Are more massive stars more likely to have planets? Read on to find out…
Nature vs. nurture in the evolution of galaxies is not completely understood. Where a galaxy is found, its environment, can play an important role in determining the properties of that galaxy. This may not always be true, however.
