A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how ...

An international team has confirmed the discovery of a super-Earth orbiting in the habitable zone of a nearby sun-like star.

Scientists believe the exoplanet HD 20794 d, six times the mass of Earth, could harbour liquid water on its surface.

It was, of course, a great joy for me when we could confirm the planet’s existence,” said Dr. Cretignier. “It was also a ...

Scientists work to define a “habitable zone,” which means that if it’s too close to a star, the water heats and evaporates, and too far, it freezes. Also, the atmospheric conditions need to be just ...

Because this planet is relatively close to Earth and orbits a bright star, it is a perfect target for future telescopes.

HD 20794 d is expected to be a focal point for upcoming projects like the Extremely Large Telescope, the Habitable Worlds Observatory, and the Large Interferometer For Exoplanets (LIFE). These ...
