A new look at the molecules in planetary nebulae, the aftermath of dying stars, hints at how they spread the raw ingredients for new stars and planets.

Researchers are looking at the very first matter to ever be present in the universe for insights into the very first microsecond of the Big Bang.

Researchers have used "asteroseismology" to examine the hidden mixing processes inside massive stars, known as the chemical factories of the universe.

Researchers have created a new map of the outer regions of the Milky Way, known as the galactic halo. The map helps confirm a theory about dark matter.

Researchers have discovered the presence of high-energy neutrinos in the wake of a star being destroyed by a black hole.
