The newly discovered world, which is 41 light-years away, is almost exactly the same size as the Earth.
The hunt for life outside of our solar system essentially boils down to finding planets that could potentially support it, which is all the more reason why this debut discovery by the James Webb Space Telescope - which is likely to lead to a plethora of other similar discoveries - is so significant.
Situated 41 light-years away in the constellation Octans, the planet - named LHS 475 b - is very similar in size to our own world and thanks to the impressive capabilities of the James Webb, we already know a lot more about it than we otherwise would.
While there is still much work to be done in analyzing this new world, scientists already know that it does not have a choking thick atmosphere like Titan - which is a good start.
"These first observational results from an Earth-sized, rocky planet open the door to many future possibilities for studying rocky planet atmospheres with Webb," said NASA's Mark Clampin.
"Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside the Solar System, and the mission is only just getting started."
