A team of astronomers have discovered evidence for yet another exoplanet orbiting Proxima Centauri, our closest neighboring star.

A nearby exoplanet orbiting within the habitable zone of a star just 4.2 light-years from Earth may be home to a vast ocean, boosting its chances of supporting life. Since its discovery, questions about the conditions at the surface of Proxima b have been swirling; the planet's mass is just about 1.3 times that of Earth's, and the red dwarf star it circles is similar in age to our sun.

A group of astronomers has discovered one of the biggest planets ever found orbiting a massive and extremely hot two-star system, despite previously believing that such an environment was too inhospitable for a planet to form in. The planet was discovered by Markus Janson, a professor of astronomy at Stockholm University, and colleagues, according to research published Wednesday in the science journal Nature.

Scientists have discovered a pair of temperate, Earth-sized exoplanet candidates around a nearby star, according to a new paper. What makes this planetary system stand out from all the others discovered in recent years is just how similar one of its planets may be to Earth.
