Looking at the night sky can be a truly amazing spectacle, but identifying what we're seeing isn't always so easy.

Space weather forecasts have become increasingly important over the years, and NASA has now decided to use AI to improve its solar storm predictions.

While scientists thought our star was going to enter an especially quiet phase, solar activity, on the contrary, has been steadily increasing for about 15 years.

Astronomers have discovered 2025 PN7, a "quasi-satellite" orbiting Earth. While not a true moon, it reveals the fascinating dynamics of our cosmic neighborhood.

Exoplanets are explored as a prospect for life outside our Solar System. But when were the first exoplanets discovered and how?

What began as a friendly joke on the Gemini III mission ended in political debate, media criticism, and a change in NASA's safety protocols.

Contrary to what we're taught in school, autumn almost never falls on the 21st of September on the calendar. While this year it will be the 22nd, at a specific time, more unlikely dates sometimes prevail: here's why!

The third interstellar object detected, comet 3I/ATLAS, is hurtling through the solar system. Although its origin remains a mystery, data from the Gaia mission allow us to reconstruct its path and possible stellar encounters.

In early July, several astronomers detected successive, particularly virulent gamma-ray bursts. This phenomenon surprised scientists.

Black holes are regions of space-time where gravity is so intense that nothing escapes. From their anatomy to their cosmic impact, we explore how they form, classify, and detect.

Chrysalis is a project that defies human imagination: a 58 km space habitat, designed for entire generations, with the goal of reaching the nearest star system.

The Moon doesn't shine on its own: what we see are reflections of the Sun on its surface. In this article, we explain, in a clear and simple way, how the eight lunar phases are formed and why they repeat in a cycle.
