A Southwest Research Institute study reveals that chasing interstellar comets like 3I/ATLAS is achievable with current rockets and instruments. Such missions could collect data on comet nuclei and comae, providing clues to the formation of other star systems. International collaborations make these rare, high-value missions increasingly realistic.

Astronomers have identified a 50-million-light-year-long cosmic filament in which 14 gas-rich galaxies all rotate in sync with the structure itself. The filament, mapped about 140 million light-years away, appears young, cold and shaped by slow cosmic flows. Galaxies on opposite ends move in opposite directions, suggesting the entire filament is spinning.

Astronomers studying the dwarf-star system TOI-3884b have uncovered a striking anomaly: the planet’s orbit is sharply misaligned with its star’s rotation. Using multicolour transit observations, researchers detected repeated starspot-crossing events that revealed the planet passes over cooler regions on the stellar surface. Follow-up monitoring showed the star rot…
