Faint White Dwarf Flux Standards: Data and Models
The Astronomical JournalFainter standard stars are essential for the calibration of larger telescopes. This work adds to the calibration spectra (CALSPEC) database of 19 faint white dwarfs (WDs) with all-sky coverage and V magnitudes between 16.5 and 18.7.

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract We present observations of the Uranian outer ring system at near‐infrared and visible wavelengths. Observations with the Keck Telescope were taken in July‐August 2007 at 2.12 and 1.63 μm, when the ring plane was almost edge‐on (ring opening angle B=0.62 $B=0.62$–0.24° ${}^{\circ}$). These data showed, for the first time, the μ ring at infrared

Eos, Transactions American Geophysical Union, 1983 The Space Telescope, scheduled for launch aboard the Space Shuttle in 1986, has been renamed the Edwin P. Hubble Space Telescope, the National Aeronautics and Space Administration (NASA) announced. The orbiting optical astronomical observatory will carry a 2.4‐m mirror and five scientific instruments that will be able to look into space 7 times farther
