A Hidden Planet: The Missing Piece? To solve these puzzles, researchers have proposed the existence of an undiscovered Earth-like planet in the Kuiper Belt. In a recent study, Dr. Patryk Sofia Lykawka ...

Astronomers have uncovered a massive hidden planet and a rare “failed star” by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope ...

There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity. Our ...

Astronomers have long struggled to find young planets hidden inside the thick clouds of gas and dust that swirl around new stars. These swirling clouds—called protoplanetary discs—are the birthplaces ...

Spectacular clouds swirl across the surface of Jupiter. These clouds contain water, just like Earth's, but are much denser on the gas giant—so thick that no spacecraft has been able to measure exactly ...

Astronomers used the James Webb Space Telescope to observe the first asteroid belt seen outside of our solar system and unveiled some cosmic surprises along the way. The space observatory focused on ...

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 ...
