Detailed measurements of stellar trajectories allowed researchers to trace the motions of stars from 5 million years ago to 2 million years in the future, uncovering 119 past flyby events in the Sco-Cen OB association.
A team has collected previous solar wind measurements at the orbit of asteroid (16) Psyche and used them to predict four possible structures for the object’s magnetosphere, which has the potential to be very complex.
Of the 26 newly discovered radio sources sporting jets, 14 are X-shaped radio galaxies and 12 are Z-shaped radio galaxies, and the optical counterparts of 17 of these 26 sources were able to be classified as well.
A new model of occultation light curves of Jupiter’s highly volcanic moon Io allows researchers to create thermal emission maps of Io’s surface without assumptions about the nature of the hot spots present.
Though the Sun’s tenuous upper atmosphere is usually enriched in easily ionized elements, under rare circumstances it can instead be depleted of these elements, reflecting behavior commonly seen in M dwarfs.
The brightness of a kilonova that results from a black hole colliding with a compact object depends on the nature of the object — collisions with theoretical stars composed of strange quarks might produce little to no light.
