The Conversation - Emerging technologies could enable interstellar travel in the coming decades.
The Conversation - Miniaturized spacecraft are being considered for interstellar voyages due to their lower cost and easier propulsion.
The Conversation - Breakthrough Starshot is a philanthropically funded venture investigating technologies for interstellar journeys using small probes.
The Conversation - Light sails are identified as a suitable form of propulsion for interstellar missions.
WHERE:
Phys.org - LHS 1140b is located approximately 48 light-years from Earth.
WHEN:
The Conversation - Future interstellar missions are anticipated to occur in the decades ahead.
WHY:
The Conversation - The interest in LHS 1140b stems from its potential to support life due to its location in the habitable zone.
HOW:
The Conversation - Light sails can be propelled by directed energy from lasers, which exert pressure on reflective membranes.
The Conversation - Accelerating a light sail to relativistic speeds would require a laser array with an effective power of tens of gigawatts.
The Conversation - Solar sails can utilize sunlight for propulsion, allowing for high-energy, long-duration missions without carrying propellant.

Astronomers are increasingly focused on the study of exoplanets, with a recent breakthrough confirming an atmosphere around the rocky exoplanet LHS 1140b, which is located about 48 light-years from Earth and sits within the habitable zone of its parent star. Researchers have found that helium is escaping from the upper atmosphere of LHS 1140b, suggesting that heavier compounds like water may exist deeper within its atmosphere, raising hopes for its potential to support life. Meanwhile, advancements in technology are paving the way for future interstellar missions, with initiatives like Breakthrough Starshot exploring the use of miniaturized spacecraft and light sails propelled by directed energy for these ambitious journeys.
