MIPAS observations of longitudinal oscillations in the mesosphere and the lower thermosphere: climatology of odd-parity daily frequency modes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
MIPAS global Sun-synchronous observations are almost fixed in local time. Subtraction of the descending and ascending node measurements at each longitude only includes the longitudinal oscillations with odd daily frequencies nodd from the Sun's ...

A Possible Solution to the Mystery of the ANITA Anomalous Events

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Strong Variability of the Modeled Venus NO Nightglow

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The ultraviolet nightglow of nitric oxide (NO) on Venus offers a unique window into the dynamics and chemistry of its upper atmosphere. We present three‐dimensional simulations of Venus' NO nightglow using a ground‐to‐thermosphere model, revealing a strong, short‐timescale variability consistent with observations.

New Climatology of Martian Water Vapor Column Abundance Derived From NOMAD LNO Nadir Observations Over Martian Years 34–38

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present a new climatology of Martian water vapor column abundance derived from nadir dayside observations made by the Nadir and Occultation for MArs Discovery (NOMAD) instrument suite as part of the ExoMars Trace Gas Orbiter (TGO) mission. H2O vertical column densities are retrieved by applying an Optimal Estimation inversion scheme to the ...

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...
