Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial planets. For years, scientists speculated about how the rocky planets—Earth, ...

Discover how scientists have used iron isotopes to determine the likely origin of the Mars-sized planet named Theia.

After the Hubble Space Telescope studied the oldest-known exoplanet in the galaxy, scientists used the James Webb Space Telescope to learn how planets were able to form in the early universe. Credit: ...

The textbook picture of how planets form—serene, flat disks of cosmic dust—has just received a significant cosmic twist. Subscribe to our newsletter for the latest sci-tech news updates. New research, ...

NASA says it was able to use the James Webb telescope to capture images of planet-forming disks around ancient stars that challenge theoretical models of how planets can form. The images support ...

Are planets in the solar system that are closer to the Sun older than the ones further away? – Gavriel, age 10, Paducah, Kentucky A cloud of collapsing gas created our Sun, the first thing to form in ...

In the swirling clouds of gas and dust that surround newborn stars, planets begin to form. These planet-forming disks are rich with clues about how worlds like Earth come to be. Until now, scientists ...

Astronomers have discovered an extrasolar planet with the largest core of any known planet. The discovery is especially exciting to planet formation theorists, because it provides extremely strong ...

Researchers at UC Santa Barbara, The University of Texas at Austin, Yale University and National Taiwan Normal University have found that a fair number of sun-like stars emerge with their rotational ...

A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. A fresh look at past data reveals that ...

A machine-learning algorithm trained on synthetic planetary systems has been let loose — and in the process has identified nearly four dozen real stars that have a high probability of hosting a rocky ...
