While most scientists believe it’s a natural comet, one Harvard astronomer has suggested its unusual features could hint at ...

Other than being a ‘Trojan Horse’ alien spaceship set to release probes to study our planet, or crashing into Earth, neither ...

Last month, Google quietly killed off Google Sky Maps. But there’s still another way to virtually explore most of the solar system a la Google Maps: it’s called Google Maps in Space. Google Maps in ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

Astronomers found that interstellar object 3I/ATLAS shows an "extreme abundance ratio" of nickel and iron in its gas plume. Astronomers are still poring over data to get a better sense of 3I/ATLAS, ...

A new analysis estimates that the asteroid belt is steadily losing mass each year, and may not be as permanent a feature of the solar system as we thought. A team of astronomers led by Julio Fernández ...

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...

While many dream of bases on Mars and cities above Venus, the reality of colonizing the Solar System is far more difficult and may be impossible with today’s technology. NATO scrambles fighter jets as ...

3I/ATLAS likely weighs more than 33 billion tons. The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say. A ...

A mysterious object hurtling through space has been identified as a rare “interstellar object,” only the third of its kind ever seen. In July, NASA reported its ATLAS (Asteroid Terrestrial-impact Last ...

The number of confirmed planets outside of our solar system—known as exoplanets—has risen to 6,000, NASA has said. There is huge variety across these distant worlds, the space agency says, with ...
