Earth-size planet found orbiting nearby star that will outlive the sun by 100 billion years
Astronomers have discovered an Earth-size exoplanet orbiting a nearby red dwarf star located around 55 light-years from Earth. Designated SPECULOOS-3 b, the planet is a rocky world that completes an orbit every 17 hours, indicating it is tidally locked to its star like the Moon is to Earth. The planet is too close to its […]
NASA-funded pulsed plasma rocket concept aims to send astronauts to Mars in 2 months
NASA is funding development of a new rocket called the Pulsed Plasma Rocket (PPR) that could drastically reduce travel time to Mars. The PPR uses nuclear power to generate high-impulse plasma thrust. This would make it far more efficient than current chemical rockets. Developers claim the PPR could cut a round-trip journey between Earth and […]
