Five young stars in one system — all the same age but at different stages of their evolution. What can they tell us?
There she blows! A detective case tracking the motion of material ejected from a star to figure out when the star exploded.
Sometimes a mystery can hide in apparently plain things. Astronomers have just discovered that a delta Scuti star known for over 40 years is actually something entirely different and full of peculiarities.

A gravitational tug-of-war between three stars has this planet living on the edge.
NN Serpentis has everything: a white dwarf + main sequence binary system that is believed to contain two planets and, now, a disc of debris.
How can we explain hot Jupiters? The answer is not completely clear yet, but we are closing in on it: it seems that binaries may play an important role on the formation of these oddball planets.
