Texas A&M researchers demonstrated laser-driven metajets—ultrathin, patterned devices—that can be steered in three dimensions by transferring photon momentum, with potential to scale to larger craft and, given enough laser power, enable a ~20-year voyage to Alpha Centauri; experiments were conducted in a fluid environment to observe controllable motion and microgravity tests are planned for space readiness.
Texas A&M researchers report a lab demonstration of micron-scale metajets with metasurfaces that can be steered in three dimensions by laser light; they say the concept could be scaled to propel larger spacecraft, potentially enabling a 20-year journey to Alpha Centauri, though real-world feasibility and space testing remain to be proven.
Texas A&M researchers demonstrated micron-scale metajets—metasurface-based devices that transfer momentum from light to lift and steer objects in 3D without contact—marking a scalable path for light-propulsion and potential interstellar missions to Alpha Centauri, contingent on sufficient optical power and funding; space-testing is the next step after fluid experiments that offset gravity.
The Chrysalis concept proposes a 36-mile rotating habitat for a one-way, 400-year journey to Alpha Centauri, designed to sustain a self-sufficient society with layered habitats, artificial gravity, and onboard manufacturing, aiming to enable humanity's first multi-generational interstellar voyage.
A Live Science poll reveals that 45% of over 3,300 respondents would consider a 400-year one-way trip to Alpha Centauri aboard a multigenerational spaceship, with opinions varying based on comfort, technology, and Earth's future conditions.
The James Webb Space Telescope has made groundbreaking discoveries including a potential Saturn-sized exoplanet orbiting Alpha Centauri A and a unique haze-driven climate system on Pluto, offering new insights into planetary atmospheres and habitability.
Scientists using JWST have potentially identified a gas giant exoplanet, Alpha Centauri Ab, in the habitable zone of Alpha Centauri A, the Sun's closest solar twin, raising exciting possibilities for life and challenging existing planet formation theories, though further confirmation is needed.
Researchers speculate that a newly discovered gas giant orbiting Alpha Centauri A, dubbed S1, could have a habitable moon similar to Pandora from the 'Avatar' movies, though its existence and potential habitability remain unconfirmed and require further observation.
A hypothetical 400-year journey to Alpha Centauri aboard a multigenerational spacecraft called Chrysalis has won a design competition, raising the question of whether people would be willing to undertake such a long, one-way space voyage.
Chrysalis is a conceptual design for a massive generational spaceship intended to transport thousands of humans to Alpha Centauri over a 400-year journey, featuring rotating habitats for artificial gravity, built at Lagrange points, and designed to sustain society across generations in deep space.
The James Webb Space Telescope has potentially discovered a new exoplanet orbiting Alpha Centauri A, just four light-years from Earth, sparking excitement for its advanced detection capabilities and implications for planetary science, although confirmation awaits future observations.
This week in science, a design for a 400-year trip to Alpha Centauri was proposed, AI models were found to transmit potentially malicious secret messages, life may exist on icy worlds beyond traditional habitable zones, ancient cranial modifications in Europe were discovered, and new deep-sea creatures were filmed in extreme ocean depths. Additionally, concerns about reduced funding for mRNA vaccines and other scientific discoveries were highlighted.
NASA's JWST may have detected a Saturn-sized planet near Alpha Centauri A, the closest sun-like star system, but the planet has only been observed once and might be temporarily hidden due to its orbit. Further observations are needed to confirm its existence, which could be the most significant JWST discovery to date if verified.
NASA's JWST may have detected a Saturn-sized planet near Alpha Centauri A, the closest sun-like star, but the planet has only been observed once and remains unconfirmed. If confirmed, it would be the closest directly imaged exoplanet in the habitable zone, though its size suggests it may not support life. Follow-up observations are planned to verify the discovery.
Astronomers using NASA's James Webb Space Telescope have found strong evidence of a Jupiter-sized gas planet orbiting Alpha Centauri A within its habitable zone, marking the closest potential exoplanet discovery around a sunlike star, though further confirmation is needed.
