The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

The study, which observed a periodic wobble in the anti-tail jet of 3I/ATLAS during July and August 2025, indicates that the ...

A novel unified hydrodynamic model proposes a single mechanism to explain the contrasting equatorial jet stream directions on gas giants (eastward on Jupiter/Saturn) and ice giants (westward on Uranus ...

Astronomers studying a disk of material circling a still-forming star inside our Galaxy have found a tantalizing result — the inner part of the disk is orbiting the protostar in the opposite direction ...

While Earth spins in the same direction as the sun, that's not the case for every planet in the solar system. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

Context. As a star evolves, the planet orbits change with time due to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion and evaporation on/by the planet.

For billions of years, the Moon has been Earth’s steadfast companion, influencing tides, stabilising our planet’s tilt, and shaping the evolution of life. Yet precise laser measurements reveal an ...

A planet's year length depends on its distance from the Sun. Planets closer to the Sun have shorter years. A planet's rotation speed is unrelated to its year length. Planets' orbital speeds vary ...

Uranus is the only planet in our solar system that rotates sideways. It has an axial tilt of about 98 degrees, which means it appears to roll around the Sun instead of spinning upright like Earth or ...
