Earthward Propagated Auroral Kilometric Radiation: Observations From Polar
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Auroral Kilometric Radiation (AKR), the strongest natural radio emission from Earth's magnetosphere, has been primarily observed in space. It is generally understood to propagate anti‐Earthward and be detected at large radial distances, while Earthward‐directed waves are thought to be blocked by the ionosphere. Surprisingly, AKR‐like emissions

Microlensing search for extra solar planets
, 2015 Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei
Astronomische Nachrichten, Volume 347, Issue 5, June 2026.ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Synthesis of organic matter by stars and its effect on the origin of life on earth [PDF]
, 2011 The last 10(5) years of stellar evolution represents the most active period of synthesis of organic compounds in a star’s life. Over 60 gas-phase molecules, including rings, radicals, and molecular ions have been identified by millimeter-wave and ...

Abiotic ozone and oxygen in atmospheres similar to prebiotic earth
, 2014 The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract We present the results of the first geological mapping of the western half of the Eminescu Quadrangle (H09) on Mercury. Multiple data sets from the NASA MESSENGER Mercury Dual Imaging System instrument were used to produce a geological map covering the area between 72°E and 108°E longitude and 22.5°N and 22.5°S latitude.
