Avi Loeb looks at SpaceX's ambitions, the exploration of habitable exoplanets like TRAPPIST-1d, and the broader implications for human space travel and settlement.
A new study says that telescopes could more easily detect exoplanets with higher levels of oxygen, akin to the Phanerozoic Eon when dinosaurs roamed the Earth.
For the first time ever, researchers using the James Webb Space Telescope have successfully measured the light coming from a sub-Neptune-sized exoplanet that orbits a star only 40 light years away.
An earth-sized exoplanet that is orbiting within its star's habitable zone has been spotted a mere 31 light years away from Earth, offering astronomers and astrobiologists a tantalizingly close new target in the search for extraterrestrial life.
A new study claims solar flares may actually make the planets in Trappist-1's habitability zone even more habitable than first thought. Teams using the James Webb Space Telescope are planning to search those same planets for chemical traces of extraterrestrial life, called 'biosignatures,' in their atmospheres.
