Mysterious space objects like ‘Oumuamua will visit our solar system again. Scientists may intercept the next one with a robotic probe.

A mysterious object called ‘Oumuamua, the first interstellar visitor ever detected, flew through the solar system in 2017. Most astronomers think it’s a comet, though ‘Oumuamua’s identity may never be fully settled. However, interstellar objects might visibly pass by once every 5 years. By the mid-2020s, powerful new telescopes may […]

A startup is developing a 100-gigawatt laser to propel a probe to another star system. That may be powerful enough to ‘ignite an entire city.’

Breakthrough Starshot wants to use powerful lasers to propel tiny robotic probes to Alpha Centauri, a nearby star system that may contain habitable planets. Yuri Milner, a Russian-American billionaire, and other Silicon Valley investors are funding the project. Starshot calls for a 100-gigawatt laser that could shoot into space and […]
