Technosignature Searches of Interstellar Objects

With the discovery of the third confirmed interstellar object (ISO), 3I/ATLAS, we have entered a new phase in the exploration of these long-predicted objects. Though confirmed discovery of ISOs is quite recent, their utility as targets in the search for technosignatures (historically known as the Search for Extraterrestrial Intelligence -- SETI) has ...

Intercepting 3I/ATLAS at Its Closest Approach to Jupiter with the Juno Spacecraft

Aerospace
The interstellar object 3I/ATLAS is expected to arrive at a distance of 53.56(±0.45) million km (0.358±0.003 au) from Jupiter on 16 March 2026. We show that applying a total thrust ΔV of 2.6755kms−1 to the lower perijove on 9 September 2025 and then ...

AI Based Velocity Calibration for Cassini's Cosmic Dust Analyzer (CDA)

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This paper presents a novel AI‐based velocity calibration method for the Cosmic Dust Analyzer (CDA) onboard the Cassini spacecraft, in particular for impacts on the large Impact Ionization Detector (IID). The legacy polynomial calibration function, derived from laboratory measurements at a dust accelerator facility, assigns a velocity ...

Artificial Broadcasts as Galactic Populations. I. A Point Process Formalism for Extraterrestrial Intelligences and Their Broadcasts

The Astrophysical Journal
Artificial broadcasts from extraterrestrial intelligences are a hypothetical class of celestial phenomena. Unlike known astrophysical objects, the societies that generate them may be able to replicate on galactic scales through interstellar travel ...

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (

Marginally Stable Nuclear Burning Triggered at Different Depths of the Neutron Star Surface in Low-mass X-Ray Binary 4U 1608-52

The Astrophysical Journal
We investigated the timing and spectral properties of the millihertz quasiperiodic oscillations (mHz QPOs) in the neutron star low-mass X-ray binary 4U 1608–52 using NICER observations. Our analysis reveals a correlation between the QPO frequency and its
