Once they reach the convective zone, however, transport becomes much faster.

What are stars like on the inside? The answer depends on their mass and, if we want to go into detail, it becomes a truly complex topic.

Solar-type stars have a layered internal structure, as shown in this nice educational video.

To be clear, the journey of energy inside the Sun is neither simple nor fast: in the radiative zone, photons produced in the core are absorbed and re-emitted trillions of times, losing energy at each interaction and taking tens of thousands to millions of years to pass through it

🌟 The Sky Above Palermo... and Beyond! 🌟

C/2025 K1 ATLAS.

3I K1 ATLAS continues to draw attention. The latest official images from ESA were released yesterday and were captured from Mars, thanks to observations by ExoMars

[Mariospiegacose @mguarce]

The fragmentation is evident in the image shown here, which was taken on November 16th, while K1 ATLAS was crossing the region of the sky between Ursa Major and Leo Minor. At that time, it was at a distance of about 0.47 AU from Earth.

Do you also think that the moons of the Solar System are as interesting as the planets?

Among icy worlds, volcanic bodies, and arid landscapes dotted with craters, the moons of the Solar System form a family of spectacular diversity. Titan, Saturn’s moon slightly larger than Mercury, is truly a chapter of its own.

The observations of these clouds confirm theoretical predictions that they tend to form in the northern hemisphere during the summer season, when the surface receives greater heating from the Sun.
