A certain rocky exoplanet could tell researchers how our solar system was formed. Scientists have made some new observations of a small rocky world that may increase our understanding of how planets were first created.
Astronomers have discovered a rare planet with some extreme seasons. Called Kepler-432b, the planet is one of the most dense and massive planets to be discovered thus far, and has temperatures that range from 500 degrees Celsius to a scorching 1,000 degrees.
A team of researchers and engineers have announced plans for a small satellite, named "Twinkle," that will give radical new insights into the chemistry, formation and evolution of planets orbiting stars.
Scientists have calculated that there may be hundreds of billions of Earth-like planets in our galaxy which could support life.
Two phenomena that are known to actually inhibit the habitability of planets may actually help chances for life. Scientists have found that tidal forces and vigorous stellar activity may promote life on certain planets orbiting low-mass stars.
Astronomers have spotted an ancient, sun-like star with orbiting planets in a system that dates back to the dawn of the galaxy. The system is the oldest to be discovered by far with Earth-sized planets, and proves that such planets formed throughout the history of the universe.
Scientists have discovered a star with three Earth-sized planets. Not only that, but one of the planets may just have temperatures that are moderate enough for liquid water, and possibly life, to exist.
The search for life on other planets continues. Now, scientists have discovered that exoplanets may be more likely to be hospitable to life and have liquid water than we thought.
Scientists are getting in some stunning exoplanet images and spectra from the first year of science operations with the Gemini Planet Imager (GPI). Now, researchers have shown these new images as the GPI continues its operations.
Astronomers have discovered eight new planets in the "Goldilocks" zone of their stars, orbiting at a distance where it's neither too hot nor too cold and where liquid water can exist on the planet's surface.
How to assemble Earth: Take elements, stir, and dash with water delivered by asteroids. Scientists are taking a closer look at how Earth-like planets are made in order to continue their hunt for exoplanets that have the likeliest chance at supporting life.
