LONDON — 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 ...

This artist’s animation shows Cha 1107-7626. Located about 620 light-years away, this rogue planet is about 5-10 times more massive than Jupiter and doesn’t orbit a star. The planet is eating up ...

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 ...

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 ...

More than 2 billion kilometers farther from the sun than Pluto, a frigid world named Makemake sports the most distant gas ever seen in our solar system, new observations reveal. “By surprise, we found ...

Astronomers have been fascinated after spotting an object earlier this year that came from interstellar space as is now hurtling through our inner solar system. Regardless, it’s an interesting visitor ...

The global water cycle has become “increasingly erratic and extreme” with wild swings between droughts and floods, spelling big trouble for economies and societies, according to a report published ...
