Astronomers have directly spotted a rare young planet, WISPIT 2b, still forming within the gap of a dusty ringed disk around a star like our sun—something long theorized but never observed until now.

Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth's orbit came from. The origin of the differing tilts in the orbits of the ...

Scientists believe they have discovered evidence of a hidden planet existing beyond Neptune, which they have named 'Planet Y'. Recently, a study analyzing the orbits of Kuiper Belt objects indicated ...

In the vast solar system, if one were to select a 'behind-the-scenes hero' whose impact on Earth is profound yet often overlooked, Jupiter would undoubtedly be the strongest candidate. This giant ...
