solar spicules

Why do spicules — tiny spikes of plasma on the Sun — appear to rotate, split, and merge? New simulations reveal the possible cause of these motions.

NGC 2467

Astrobites reports on why interstellar magnetic fields can appear ordered or tangled, depending on which gas clouds you measure and how.

A Pulsar in a Rare Triple System

Researchers have discovered a millisecond pulsar with two stellar companions — one of only a handful of these rapidly spinning stellar remnants known to be in a triple system.

The hot Jupiter WASP-12b is on a collision course with its host star, and it’s heading that way faster than expected. New research examines a possible explanation for the planet’s speedy inspiraling.

A new catalog of giant pulses from the Crab Nebula pulsar reveals a feature predicted to exist but not seen until now.

SPHEREx

Astrobites reports on NASA’s SPHEREx mission, which is collecting an infrared spectrum for every point in the sky — potentially revolutionizing our understanding of cosmic inflation, galaxy formation, and interstellar ices.

AT 2025ulz within its host galaxy

Last year, gravitational wave detectors triggered on what may have been a collision involving a sub-solar-mass neutron star. New research investigates a potential link between this event and a supernova.

New simulations suggest the outer solar system could disassemble within about one billion years after the Sun becomes a white dwarf.
