When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...

Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known ...

Canada has proposed the POET mission to find Earth-sized exoplanets orbiting ultracool dwarf stars, potentially accelerating the search for habitable worlds. Building on previous microsatellite ...

Space telescopes are revolutionizing exoplanet discovery, allowing astronomers to detect Earth-like worlds orbiting distant stars. By observing subtle dimming of starlight, measuring gravitational ...

Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David ...

The James Webb Space Telescope (JWST) has opened a new chapter in planetary science, giving astronomers the ability to observe JWST exoplanets with a level of detail never before possible. Launched as ...

Scientists may need to broaden their horizons in their search for alien life. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists argue ...

Scientists have uncovered a surprising way to study the harsh space weather around young M dwarf stars. Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ ...
