A Case Study of Interstellar Material Delivery: α Centauri

The Planetary Science Journal
Interstellar material has been discovered in our solar system, yet its origins and details of its transport are unknown. Here, we present α Centauri as a case study of the delivery of interstellar material to our solar system.

The Feasibility of a Spacecraft Flyby with the Third Interstellar Object 3I/ATLAS from Earth or Mars

The Astrophysical Journal
We investigate the feasibility of a spacecraft mission to conduct a flyby of 3I/ATLAS, the third macroscopic interstellar object discovered on 2025 July 1, as it traverses the solar system.

Nucleus and Postperihelion Activity of Interstellar Object 3I/ATLAS Observed by the Hubble Space Telescope

The Astrophysical Journal Letters
We report the detection of the nucleus of interstellar object 3I/ATLAS, using a nucleus extraction technique on Hubble Space Telescope (HST) observations taken between 2025 December and 2026 January.

Interstellar Objects in the Solar System

1I/`Oumuamua and 2I/Borisov are the first macroscopic interstellar objects to be detected in the solar system. Their discovery has triggered a tsunami of scientific interest regarding the physical properties, dynamics and origin of the so-called interstellar interloper population.

Evidences of Two Merging Elongated Filaments Associated with AGAL323.444+0.096 and Star Formation

The Astrophysical Journal
We study the structure, kinematics, and star-forming activity of filamentary cloud F-NE associated with AGAL323.444+0.096 using ^13 CO ( J = 2–1) molecular line and continuum data from the far-infrared to near-infrared.

Cosmic–climatic futures: interstellar objects, solar variability, and planetary consciousness (2027–2032)

European Journal of Futures Research
Purpose This manuscript evaluates plausible systemic risk pathways arising from the contemporaneous increase in interstellar object (ISO) detections, the peak phase of Solar Cycle 25 (including major coronal mass ejections), and accelerating socio ...

Optical Design of the far Ultraviolet Imaging Spectrograph [PDF]

Journal of Astronomy and Space Sciences, 1998
We present the design specifications and the performance estimation of the FUVS (Far Ultraviolet Spectrograph) proposed for the observations of aurora, day/night airglow and astronomical objects on small satelltes in the spectral range of . The design of

Uncovering the Hidden Physical Structures and Protostellar Activities in the Low-metallicity S284-RE Region: Results from ALMA and JWST

The Astrophysical Journal
We present an observational study of the S284-RE region, a low-metallicity area associated with the extended S284 H ii region. A thermally supercritical filament (mass ∼2402 M _⊙ and length ∼8.5 pc) is investigated using the Herschel column density map ...

The NANOGrav 15 yr Dataset: Search for Gravitational Scattering of Pulsars by Free-floating Objects in Interstellar Space

The Astrophysical Journal
Free-floating objects (FFOs) in interstellar space—rogue planets, brown dwarfs, and large asteroids that are not gravitationally bound to any star—are expected to be ubiquitous throughout the Milky Way. Recent microlensing surveys have discovered several
