As solar cycle 25 ramps up, so too do our predictions; researchers predict that the peak of the current solar cycle will be similar to the previous cycle or slightly stronger, with similar rates of geomagnetic storms.
Though pulsars are thought to spin extremely regularly, some pulsars show irregular behavior; J1701−3726 has a whole host of strange behaviors, including periods where the pulses nearly disappear.

Observations of more than 1,000 blazars — active galactic nuclei with jets pointed almost directly toward Earth — provide a way to investigate how these jets are launched.

Increased temperatures around protostars may result in the enhancement of oxygen-poor molecules like acetonitrile compared to oxygen-rich molecules like methanol.

A cataclysmic variable system might be a precursor to a black widow pulsar system; if the system’s white dwarf accretes enough material, it will become a neutron star that feeds off its low-mass stellar companion.

Planetary systems with giant outer planets may exhibit more irregular spacing between the inner planets compared to systems without giant planets, giving a new way to identify systems containing unseen giant planets.
