A new method of measuring star formation in the earliest galaxies finds that they’re producing more massive stars than expected — a result that could affect our understanding of how galaxies grow their stars.
A simple experiment has detected a signal from the first stars forming just 180 million years after the Big Bang. The observations have intriguing implications for the nature of dark matter.
Results from the first data release of the Dark Energy Survey include eleven new stellar streams in the Milky Way galaxy.
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
Our galaxy's center region is producing gamma rays, but astronomers are still debating whether pulsars or dark matter are the source. Three recent studies tackle the debate head-on.
