Massive stars, those weighing between 10 and 100 times the mass of our Sun, are the universe's heavyweights, playing pivotal roles in shaping galaxies and influencing cosmic evolution.

After more than 50 years, a Soviet satellite is about to re-enter Earth's atmosphere. The impact is expected in the coming days, between this Friday and Sunday, at a still unknown point on our planet.
Regardless of their size, composition, or position in the Universe, all planets adopt a spherical shape, a phenomenon that can be explained "simply" by physics.
Soviet-era spacecraft Kosmos 482 is expected to make an uncontrolled reentry after 50 years in orbit, with its exact landing time and location still unknown.
In Hawaii, twice a year, the sun aligns perfectly with the vertical line. At that precise moment, objects cast no shadows.
New observations from the James Webb Space Telescope have shed light on the darkness of the early Universe, showing how the first stars and galaxies emerged from the Dark Ages.
We discover the chaotic atmosphere of the gas giant Jupiter, the most extreme planet in our solar system with giant lightning strikes and balls of ice and ammonia called mushballs.
The Martian canyons and valleys, so similar to those on Earth, were formed by the erosion of rivers fed by rain and snow, rather than by the melting of the polar ice caps, a recent study reveals.
Designed for a mission of just two years, the Curiosity rover has already exceeded all expectations with more than a decade on Mars. We review the small robot's five most impressive discoveries on Martian soil.
Although the existence of planets orbiting orthogonally to two stars had already been theorized, it is only recently that such a planet has actually been observed for the first time.
The Giant Magellan Telescope will be a true giant in the telescope family. With its seven mirrors, each 8.4 m in diameter, it will be, along with the Extremely Large Telescope, the largest ever built.
Astronomers have discovered that super-Earths orbit not only close to their stars, but also at great distances, expanding our expectations about habitable worlds beyond the solar system.
