In the search for extraterrestrial intelligence, researchers are interested in Barnard’s star, the second-closest star system to Earth, and have predicted what a signal originating from the system might be like.
Multiwavelength observations suggest that ASASSN-14ko is a repeating tidal disruption event — a star being torn apart bit by bit by a supermassive black hole — but modeling is needed to explore the data further.
A new model used to characterize Martian dust analogs takes into account irregularly shaped dust particles and can be used in scattering and radiative-transfer models of the Martian atmosphere.
Seismic events picked up by the InSight lander have been definitively linked to new impact craters on Mars, bringing the total number of impact-related seismic events to eight.
Researchers have detected molecules and dust in a recurrent nova — a decidedly hostile environment that may contain a narrow region capable of forming and maintaining molecules.

The solar wind is filled with waves of oscillating plasma, and ion waves appear to be more common closer to the Sun than farther away, due to the factors that excite waves in the first place.
