The Interstellar Boundary Explorer (IBEX) team presents the three most recent years of data, explores long-term variations, and provides maps that separate the “ribbon” feature from the global flux of neutral atoms.

The existence of runaway greenhouse planets may create a discontinuity in radius–density space, and the PLAnetary Transits and Oscillation of stars (PLATO) mission has the potential to detect this discontinuity.

Several purported high-redshift active galactic nuclei identified in JWST images have been revealed via spectroscopy to instead be brown dwarfs, including the most distant brown dwarf yet discovered.

Researchers examine the importance of uncertain reaction rates on our calculations of pycnonuclear fusion — a type of slowly progressing nuclear fusion that rarely occurs outside extremely dense environments.

JWST confirms what was only hinted at by previous infrared telescopes: icy pebbles do migrate inward in compact disks more readily than they do in larger disks with deep gas gaps.

A search for transit depth variability among 330 previously discovered exoplanets turns up four promising candidates; of those four, only one has variability likely due to the planet or its host star.
