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.
There may be a new way to tell the age of stars. As stars grow older, they slow down in terms of their spin. Now, astronomers are taking advantage of this fact to tackle stellar ages.
Scientists have found out that oceans on super-Earths, once established, can actually last for billions of years, which may explain a bit more about our own planet.
Although the Kepler spacecraft's primary mission came to an end when the second of four reaction wheels used to stabilize the spacecraft failed, scientists have come up with an ingenious strategy to control Kepler and use it in a new mission.
Astronomers may soon discover rocky planets that have been stretched out by the gravity of the stars that they orbit. The new findings could reveal a bit more about these alien planets.
