New calculations reported by Live Science indicate Jupiter was once much larger and is still contracting as it cools, offering constraints on early solar system conditions.

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 ...

A groundbreaking study has unveiled a startling portrait of Jupiter‘s early days, revealing the gas giant was once nearly twice its current size and wielded a magnetic field about 50 times stronger ...

Scientists have measured that Jupiter releases more internal heat than it absorbs from the Sun, based on observations of its structure, rotation, and atmospheric behavior.

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 ...

Meanwhile, Harvard astrophysicist Avi Loeb, who flagged at least 16 anomalies on 3I/ATLAS has reiterated intensive monitoring ...
