Proxima Centauri b is the closest known exoplanet that could be in the habitable zone of its star. Therefore, it has garnered a lot of attention, including several missions designed to visit it and send back information. Unfortunately, due to technological constraints and the gigantic distances involved, most of those missions only weigh a few grams and require massive solar scales or pushing lasers to get anywhere near their target. /news/2025-07-fusion-proxima-centauri-potentially-habitable.html Space Exploration Mon, 07 Jul 2025 15:02:03 EDT news671119321 As the global demand for clean and sustainable energy continues to surge, the photovoltaic sector remains at the forefront of this transition.
