Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

A solar eclipse is a rare, visually striking phenomenon. The Moon passes between Earth and the Sun, temporarily hiding our star – a geometrical alignment spanning millions of miles. A partial solar ...

As a NASA spacecraft whizzed away from Earth at 40,265 mph, it took a brief moment to look over its robotic shoulder at how far it's traveled. Psyche, a mission and orbiter named after its space ...

At the ripe age of five, it is clear that the United States Space Force, while dominated by old thinking, still doesn’t know what it wants to be when it grows up, and is split among multiple different ...

The Solar System is much more than a collection of planets, moons, comets, and asteroids. It is our home in the cosmos. The Solar System's only star, which we call the Sun, plays a role in nearly ...

Spiral Galaxy from Kirkland et al. CREDIT Chris Kirkland and colleagues. A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust ...

Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for ...

The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its ...

Earth’s magnetic shield may not have the safety limit scientists once thought it did. New research suggests that the most powerful solar storms could disturb the planet’s upper atmosphere up to twice ...

A long-ago reshuffling of the giant planets in our solar system may have been instrumental in giving Earth its moon. For decades, planetary scientists have hypothesized that Jupiter, Saturn, Uranus ...

And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.
