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 ...

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Interstellar Travel and Traversable Wormholes

, 2014
Sending Starships into deep space is a dream that human being has begun to consider when the first flight had success. Since then a lot of progress has been done but without breaking the ultimate barrier we have to pass: the speed of light.

Frequency Standard Contributions to Limitations on the Signal‐to‐Noise Ratio in Very Long Baseline Interferometric Observations

Radio Science, Volume 61, Issue 6, June 2026.
Abstract Since its observation in 2019, the first image of a super‐massive black hole using Very Long Baseline Interferometry (VLBI) with an Earth‐scale baseline has generated much scientific and public interest. Work is now underway to extend the baseline into space to obtain higher image resolution.

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 ...

How to Imagine Educational AI: The Filling of a Pail or the Lighting of a Fire?

Educational Theory, Volume 76, Issue 3, Page 316-338, June 2026.
Abstract Recent advances in artificial intelligence (e.g., machine learning, generative AI) have led to increased interest in its application in educational settings. AI companies hope to revolutionize teaching and learning by tailoring material to the individual needs of students, automating parts of teachers' jobs, or analyzing educational data to ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

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 ...

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
