Explore the fascinating worlds of Planetary Science and Geophysics, uncovering mysteries of the cosmos and Earth's processes.

For millions of years, a fragment of ice and dust drifted between the stars—like a sealed bottle cast into the cosmic ocean. This summer, that bottle finally washed ashore in our solar system and was ...

The Hubble Space Telescope captured a detailed image of NGC 6000, a barred spiral galaxy. It displays a yellow core of old stars and blue arms with yo ...

3I/ATLAS, an interstellar object currently zipping through the solar system, is capturing the attention of astronomers, the public and even most of our deep space assets. Its hyperbolic orbit tells us ...

We all need some space sometimes—but it's harder to find than you might think. How far into our universe do we have to go to reach somewhere truly empty?

In a new study published on arXiv, a team determined that the interstellar comet could be older than the solar system's Sun. Researchers believe that the comet originated in the Milky Way Galaxy, but ...

Asteroid ‘Families’ Reveal Hidden Histories and Impact Risks across the Solar System ...

Lying between Mars and Jupiter is a massive ring of rock debris—the asteroid belt. Now thin, it’s fading away gradually. In a new study, planetary scientist Julio A. Fernández of Uruguay’s Universidad ...

Exoplanet hunters Christopher Watson and Annelies Mortier explain the long search for a 'twin Earth' capable of sustaining life.

Dark comets are a unique type of cosmic object. While they may look like asteroids, they are actually comets with unusual shapes and distinct characteristics.

Hubble’s latest image captures the dazzling spiral galaxy NGC 6000, lying 102 million light-years away in Scorpius. Its golden core and bright blue arms reveal a striking contrast between old, cool ...

New research suggests that planets outside our solar system contain far less surface water than scientists once believed. Contrary to earlier theories that these exoplanets might be covered by deep ...
