More than a decade ago, a Japanese construction company unveiled a plan to build a massive belt of solar panels around the Moon’s equator. The concept, called the Luna Ring, would stretch for 6,800 miles and generate uninterrupted solar power without any of the weather or darkness problems that plague Earth based arrays.

Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the inner solar system, with outer solar system contributions limited to just a few percent of the planet’s total mass.

A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed almost entirely from nearby material rather than distant sources. Planetary scientists have long debated the origin of the material that formed Earth.

The Artemis II crew flew farther from Earth than any humans in history as they passed over the far side of the moon on Monday night.

The world has tracked the journey of NASA’s Artemis II mission for five days. The four astronauts have launched into space, tested life support and other important systems of their Orion spacecraft, tangled with the vehicle’s toilet,

Last month, Earth was treated to a massive aurora borealis that reached as far south as Texas. The event was attributed to a solar storm that lasted nearly a full day and will likely contend for the strongest of 2026. Such solar storms are usually fun for ...

A new NASA spacecraft has started tracking the particle streams that can make a massive solar flare dangerous while mapping the Sun’s shield. That pairing connects short-term storm warnings near Earth with the far boundary that helps block harsher radiation from deep space.

Every day on Earth, you experience weather. You feel the wind blowing and see clouds move across the sky. Sometimes there are storms where the wind gets really strong, it might rain, or there might be thunder and lightning. Did you know that there’s ...

EU researchers are developing powerful new telescopes to help uncover Earth-like planets around distant stars and advance the search for extraterrestrial life. Solar storms captured the imagination of much of the American public earlier this year when ...
