Hubble Unveils the Largest and Most Chaotic Planet Nurseries

Astronomers have captured the first visible-light image of 'Dracula’s Chivito,' the largest and most chaotic planet-forming disk ever observed, located about 1,000 light-years away. This massive, asymmetric disk exhibits unusual features like extended filaments on one side, challenging previous assumptions about the serenity of planet nurseries. It serves as a scaled-up model of early solar system conditions, offering new insights into the complex processes of planet formation.

Hubble Captures First Direct Images of Cosmic Collisions in Nearby Star System

Astronomers captured the first direct images of collisions between large objects in a nearby star system, Fomalhaut, providing insights into planet formation and the behavior of planetesimals, with observations suggesting these icy bodies are similar to solar system comets. The study highlights the importance of understanding dust clouds and collisions in young planetary systems to distinguish them from planets.

Hidden Mantle Structures May Hold Keys to Earth's Origins

A new study suggests that massive structures in Earth's mantle, called LLSVPs and ULVZs, are remnants of early Earth’s chaotic formation, influenced by material leaking from the core, which helps explain Earth's habitability and surface activity.

Mini-Neptunes May Have Solid Surfaces, Not Lava Worlds

A new study suggests that many mini-Neptunes, previously thought to be covered in magma oceans, may actually have solid surfaces due to high atmospheric pressure compressing their rocky cores, challenging previous assumptions about these common exoplanets.

Ancient 'Heavy Water' Found in Planetary System, Revealing New World Formation

Astronomers have detected doubly-deuterated water (heavy water) in a young star's planet-forming disk, indicating that this water is older than the star itself and likely inherited from interstellar clouds, which has implications for the origins of water on planets including Earth.

Scientists Discover How Exoplanets Generate Water from Rocky Cores and Hydrogen Atmospheres

Experimental evidence shows that high-pressure magma–hydrogen reactions can produce significant amounts of water within hydrogen-rich sub-Neptune planets, suggesting these planets could become water-rich through internal processes rather than solely through formation outside the snow line, challenging traditional models of planet formation.
