Scientists may have found the first planet ever detected around our closest “solar twin,” a star called Alpha Centauri A, the same real-life star that was home to the fictional moon Pandora in James ...

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable orbit around Alpha Centauri A, the nearest sunlike star to our solar system ...

The first-ever images of the sun’s south pole reveal a messy jumble of magnetic activity in a never-before-seen region of our nearest star. The images, taken by the Solar Orbiter spacecraft and ...

A spacecraft developed by European scientists and companies has captured unprecedented new views of the Sun’s south pole. Built by Airbus in the UK, Solar Orbiter was developed as part of a joint ...

New research from the University of St Andrews has proposed that particles in solar flares are 6.5 times hotter than previously thought. The research provides an unexpected solution to a 50-year-old ...

The sun will never set on NASA's Solar Dynamics Observatory, which will aim its cameras at our nearest star from an orbit matching the Earth's rotation after its scheduled launch Tuesday. That will ...
