Far beyond the reach of any spacecraft, a distant world glows with heat so intense that rock itself turns to vapor. In that ...

The JWST discovers an impossible anomaly on TOI-5205 b and challenges everything we thought we knew about giant planets.

Exoplanet TOI-5205 b is weird for a bunch of different reasons, and now we can add its low metallicity to that list.

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...

Since then, astronomers around the world have been studying the planet’s composition through a range of techniques including ...

Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet surveys suggest that just four layouts may dominate the universe. Drawing on ...

Planets are born from the rotating disk of gas and dust that surrounds a star in its youth. While it is commonly accepted ...

Talk about a hot mess. Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees Fahrenheit — hot enough to melt rock into a churning ocean of magma and ...

The closest planet to our sun, Mercury, experiences extreme temperature variations. Since the planet has no atmosphere to ...
