Astronomers have made a groundbreaking discovery that challenges our understanding of gas giant formation within our solar ...

That is the provocative question at the heart of the latest developments surrounding the interstellar comet 3I/ATLAS, as new NASA data sharpen the picture of its composition while an unusual orbital ...

The internal structure of gas giant planets may be more complex than the commonly assumed core-envelope structure with an adiabatic temperature profile. Different primordial internal structures as ...

How do exoplanets evolve throughout their lifetimes, specifically those known as “hot Jupiters”, which have been found to orbit extremely close to their parent stars? This is what a recent study ...

Jupiter’s early growth carved rings in the solar system, delayed meteorite formation, and kept planets like Earth in stable ...

"Tidal heating plays an important role in the heating and orbital evolution of celestial bodies," said Alex Hayes, professor of astronomy. "It provides the warmth necessary to form and sustain ...

Europa may have a metamorphic origin for the ocean. While some scientists speculated this, a research team shows that if Europa indeed formed from hydrated rocks (i.e., rocks have hydrogen and oxygen) ...

The talk of the day in the world of telescopes in the James Webb. Later in December, an Ariane 5 rocket will launch the fancy hardware into orbit, opening the doors for a new age in space exploration.

Jupiter's moon, Europa, is slightly smaller than Earth’s moon and is one of the most promising places to search for alien life. Amid the Jovian system, Europa is of particular interest to scientists ...
