Since the first fast radio burst (FRB) was discovered in 2007, astronomers have been puzzling over their source. These bright radio flashes come from seemingly random directions across the universe. Finally, astronomers have pinned down one FRB to a specific neutron star in a galaxy about 200 light-years away. The FRB was unleashed from a region within 10,000 km of the neutron star and probably emerged from its magnetosphere.

Some white dwarfs have planets, but to be habitable worlds they would need to hold on to their oceans during the star's red giant stage.

Trans-Neptunian Objects are the icy remnants of our early solar system. Part of their history can be found in the spectra of molecules and dust on their frozen surfaces.

Dark energy is central to the standard model of cosmology, but the Timescape model suggests dark matter doesn't exist.
