A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...

It's been nearly a month since the second interstellar object, C/2019 Q4 (Borisov), was detected. And this newly identified object could potentially be studied, according to a new study. The research, ...

A new study shows that a solar sail may face drag force from the very light that powers it.

A new study suggests laser-driven interstellar lightsails may face a hidden efficiency problem as the very light pushing them starts behaving less helpfully.

Interstellar travel could be possible, scientists say, but not in the way you might think. For decades, science fiction stories have proposed the idea of traveling outside of our known galaxy. This ...

A new study notes that interstellar comet 2I/Borisov did break up after it came close to the sun, but seems likely to survive and continue its journey through the Solar System. The research, which can ...

Researchers at Cornell University have assembled a shortlist of rocky exoplanets sitting inside their stars’ habitable zones, ranking them as plausible destinations for an interstellar probe that ...

Ever since interstellar object 3I/ATLAS streaked into our solar system, astronomers have been scrambling to understand how this likely comet got here—and more importantly, perhaps, where it came from.

One of the film’s most memorable scenes shows Cooper sending messages to his daughter from inside a black hole. While the sequence was designed as science fiction, new research suggests the underlying ...
