A distant gas giant the size of 10 Jupiters is now the first planet outside Earth's solar system to be mapped in three dimensions.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered that aging stars in their so-called "red giant" phase are even more destructive to their orbiting planets than previously suspected.

It’s often assumed that Earth is somehow separate from the rest of the universe. Yet changes in environments across the solar system have profoundly influenced the history of humanity. Beginning in the 14th century,

We know of three interstellar objects (ISO) that have visited our inner solar system. Oumuamua was the first one, and it came and went in 2017. 2l/Borisov, an interstellar comet, was next, appearing in 2019.

Since the dawn of civilization, humanity has wondered whether we are alone in the universe. Some people—myself included—believe that there is surely life

The first map of magnetic fields in a planetary formation disk has been created, revealing how invisible forces shape the birth of new worlds.

An asteroid named 2025 PN7 has been in quasi-orbit of Earth for approximately 60 years. It's expected to stay there for another 60 years, too.

There are no confirmed exomoons, moons orbiting distant exoplanets in other solar systems. There are a few candidates, but none have passed the threshold and been accepted as confirmed. But they must exist.

Hidden deep in ancient rocks, scientists have found the surviving traces of Earth’s first form—unchanged for 4.5 billion years.

Ancient rocks reveal a potassium-40 deficit, the first physical evidence of the proto-Earth and insights into early planetary chemistry.
