A growing fleet of satellites is monitoring man-made greenhouse gas emissions from space, spurred by the need to track down major sources of climate changing gases such as methane and carbon dioxide. […]

"Super-Earths" and Neptune-sized planets could be forming around young stars in much greater numbers than scientists thought, new research by an international team of astronomers suggests. […]

A new study led by scientists from the Instituto de Astrofísica de Canarias (IAC) reveals that the giant exoplanet WASP-69b carries a comet-like tail made up of helium particles escaping from its gravitational field and propelled by the ultraviolet radiation of its star. The results of this work are published today in the journal Science. […]

An international group of scientists has developed a new method for analyzing the sun's energy outbursts, which can help better understand and predict extreme space weather phenomena that directly affect the operation of engineering systems in space and on Earth. The results of their study were published in the Astrophysical Journal. […]

The SPECULOOS Southern Observatory (SSO) has been successfully installed at the Paranal Observatory and has obtained its first engineering and calibration images—a process known as first light. After finishing this commissioning phase, this new array of planet-hunting telescopes will begin scientific operations, starting in earnest in January 2019. […]
