The millisecond pulsar PSR J1023+0038 is known to switch between two brightness modes almost constantly, something that until now has been an enigma. This artist’s impression shows the millisecond pulsar PSR J1023+0038 stealing gas from its companion star. Image credit: ESO / M. Kornmesser. PSR J1023+0038 is a 1.69 ms radio pulsar located about 4,500 light-years away in the constellation of Sextans. Discovered in 2007, it orbits a low-mass (0.2...

Plasma is constantly streaming away from the Sun, forming the solar wind. A likely source of this plasma is coronal holes, regions of the Sun’s corona with magnetic field lines that open outward. Chitta et al. observed a coronal hole in the extreme ultraviolet using the ESA/NASA Solar Orbiter spacecraft and identified several types of small-scale jets within it. Large numbers of jets occurred during the observation, but each one lasted only a few dozen seconds. The authors calculated that the jets provide enough energy and plasma to supply a large fraction of the solar wind, at least during quiet periods.
