Despite the aggressive marketing efforts by Disney and NASA to promote space travel, public interest remains low as of August 4, 2025. This highlights a significant disconnect between interstellar ambitions and real-world buy-in.

From Christopher Nolan's Interstellar to the iconic Back to the Future series, here are the best time travel movies.

AUSTIN (KXAN) — Exploring beyond our solar system could have lasting impacts here on Earth, and scientists, creatives and industry experts gather at the University of Texas at Austin this week to discuss the possibilities. The 9th Interstellar Symposium ...

Scientists have been searching for radio signals from hypothetical alien civilizations using radio telescopes for decades.

Another interesting consequence of relativity is that as time stretches out at high speeds, distances diminish. It’s hard to wrap our heads around but it’s true. If our alien civilization experiences time dilation by a factor of 100, then everything in the cosmos would also appear (and actually be) 100 times closer.

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks. When it comes to space travel, Albert Einstein's theory of relativity is a major inconvenience. With the laws of physics (currently) prohibiting ...

Anyone who studies planetary formation would relish the opportunity to get a close-up look at an interstellar object. Sending a mission to one would undoubtedly yield a scientific payoff. There’s a good chance that many of these interlopers have been around longer than our own 4.5 billion-year-old Solar System.
