For lightning to be responsible for the level of nitric oxide estimated to be present in Venus’s atmosphere, it must release more energy per strike or strike more frequently than it does on Earth.
A new pipeline increases the signal-to-noise ratio of detected gamma-ray bursts, increasing the detectable volume for these bursts and leading to the detection of hundreds of soft gamma-ray flares in our galaxy.
The characterization of 30 white dwarfs with excess infrared emission suggesting the presence of a cool stellar companion will advance our understanding of white dwarf evolution in binary systems.
The first three-dimensional radiation–magnetohydrodynamics simulations of brown dwarf formation support the hypothesis that these objects form in a star-like way.
An extremely luminous and massive galaxy with excess blue emission in the rest-frame ultraviolet may provide an example of what the mysterious “little red dot” galaxies evolve into.
Low-metallicity M-type subdwarfs, late M dwarfs, and what appear to be L and T dwarfs make up the 127 newly discovered high-proper-motion objects from the United Kingdom Infrared Telescope Hemisphere Survey.
