Scientists are sucking carbon dioxide from the air with giant fans and preparing to release chemicals from a balloon to dim the sun's rays as part of a climate engineering push to cool the planet.

Seven small planets whose surfaces could harbour liquid water have been spotted around a nearby dwarf star. If such a configuration is common in planetary systems, our Galaxy could be teeming with Earth-like planets.

Agricultural systems for space have been discussed since the works of Tsiolkovsky in the early 20th century. Central to the concept is the use of photosynthetic organisms and light to generate oxygen and food. Research in the area started in 1950s and 60s through the works of Jack Myers and others, who studied algae for O2 production and CO2 removal for the US Air Force and the National Aeronautics and Space Administration (NASA).

Scientist have developed a set of five instruments that can potentially advance NASAs understanding of wind and weather conditions on the surface of Mars that can help ascertain the planet's habita

European astronomers on Wednesday announced their discovery of a small rocky planet potentially hospitable to life circling the star closest to our own solar system—our nearest neighbor in a galaxy

Two potentially habitable rocky planets have been discovered with Nasa's Kepler telescope during a 'round-up' of exoplanets in which more than 100 new worlds were found.

An international team of astronomers has announced the discovery of a new dwarf planet in our Solar System, finding a distant object beyond Neptune that circles the Sun in a spectacularly wide orbi

Liquid water is a requirement for life on Earth.

The Juno satellite, which left Earth five years ago, had to fire a rocket engine to slow its approach to the planet and get caught by its gravity.

Mars used to have far more oxygen than it does now, scientists have said, potentially making it far more Earth-like (and possibly habitable) than previously believed.
