New research shows hot Jupiters find safety in numbers. According to radial velocity data, these giant exoplanets are more commonly found around stars in open clusters.
Omega Centauri is a huge globular cluster, so much so that some astronomers think it could be the remnant of a disrupted dwarf galaxy. We will see that this is not necessarily true.
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.
