The IceCube neutrino telescope reports its most extensive search for neutrinos produced by dark matter annihilations in the Sun.

A new model shows that the nonuniform heating of ions in the solar wind may be explained by resonant interactions with a particular type of plasma wave.

The H.E.S.S. Collaboration has put bounds on the flux of very-high-energy gamma rays that could be produced by annihilations of dark matter particles.

A precise mass measurement of an exotic zinc isotope gives new insight into the composition of the crust of neutron stars, the possible birthplace of heavy elements.

Contrary to the common view, the gravitational lensing from cosmic voids causes a brightening—not a dimming—of background objects, according to new calculations.

Cosmic gamma-ray bursts turn out to be polarized, which rules out the breaking of a fundamental symmetry down to the lowest limits ever observed.

Glitches in the rotation of pulsars cannot be explained by the conventional model of superfluid neutrons beneath the star’s crust.

Three major drawbacks to the ΛCDM dark matter model of the universe may be ameliorated if a proposed particle couples to dark matter and to neutrinos.

A new way of topologically labeling the pasta phases thought to exist in neutron stars could help researchers sort out how the phases contribute to star cooling.

A theoretical model of sunspots shows that their occasional disappearance may be due to a combination of fluctuations in the Sun’s polar magnetic field and outer layer flows.

New calculations of core-collapse supernovae show how bizarre nuclear structures—called pasta—develop in the dense core of a dying star.

Proposed measurements of arrays of pulsars could reveal the secrets of how supermassive black holes form, behave, and evolve.

Quantum repeaters, devices that have been proposed for transporting encrypted information, could help collect light from distant telescopes in large area arrays.

Changes in the diffusion constant of cosmic rays due to self-induced turbulence may explain unexpected features in the cosmic-ray spectrum.

A new analysis shows that it is possible to look for dark-matter particles with mass far below 1 giga-electron-volt by using atomic ionization.

Experiments show that magnetic waves in a plasma may be effective at controlling energetic electrons.

Interactions between primordial photons and axions may be why the accepted model of nucleosynthesis overestimates the abundance of the isotope lithium-7.

Theorists suggest that the weeks-long flare measured last year from a distant galaxy was probably beamed by a jet of material aligned with the rotational axis of a mammoth black hole.

An underground neutrino detector has found the first evidence of a nuclear reaction that produces deuterium in the sun.

A crust-busting vibration of a neutron star—induced by a merger with another dense object—may explain pre-emptive flashes for some gamma-ray bursts.
