Astronomers have obtained the sharpest images ever taken of a bright, long-studied asteroid in the main belt and found ...

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 ...

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 ...

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 ...

Far beyond the planets, past even the most distant dwarf worlds, lies a vast shell of icy debris that marks the true outer ...

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 ...

From meteorites that impact Earth, to a moon that orbits backwards, to an imposter lurking in the asteroid belt, a variety of strange, wandering worlds are rewriting what we know – and even how we ...

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 ...

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 search for life beyond Earth has marked a new discovery — evidence of an atmosphere on an Earth-like planet beyond our Solar System with modelling suggesting it may be a water world.

Approximately 4.5 billion years ago, a cold cloud of gas and dust buried deep in one of the Milky Way galaxy’s spiral arms started to collapse. From there, gravity worked its magic. The cloud began to ...
