Hubble Captures Rare Collision in Nearby Planetary System, Revealing Violent Planet Formation
Astronomers using NASA’s Hubble Space Telescope have witnessed rare collisions between rocky bodies in the Fomalhaut system. The glowing debris clouds created by these impacts offer a unique glimpse into how planets form and highlight challenges in identifying true exoplanets.

Hubble Spots White Dwarf Devouring Icy Pluto-Like Planet 260 Light-Years Away
Using Hubble’s ultraviolet spectrograph, scientists detected carbon, nitrogen, sulphur, and abundant oxygen falling onto a white dwarf 260 light-years away, evidence of an icy planetesimal being torn apart. The find shows volatile worlds can persist into a star’s final stages, offering a preview of the Sun’s distant fate.

Trillions of Comets Found in 74 Alien Star Systems, Unveiling Exocomets and Planetary Belts
A discovery of trillions of comets in 74 star systems has opened new doors for understanding the role of exocomets in planetary water sources. The planetesimal belts, detected using ALMA and SMA telescopes, offer crucial insights into the evolution of planetary systems and the potential for life-supporting water on distant planets. This research pa...

Earth's Formation Explained With the Help of New Theory Using Laboratory Experiments, Computer Simulations
In a recent study to understand the composition of the Earth, researchers at ETH Zurich created dynamic models and simulated the formation of planets. Researchers ran simulations and collided thousands of planetesimals with each other in the early solar system. They observed that a mixture of several different planetesimals could lead to Earth's co...

Juno's Study Provides Insight on Jupiter's Composition, Gravitational Field
A new study has researched about Jupiter's metal concentration and distribution, suggesting that the planet ate a lot of rocky planetesimals when it was young. The authors sought to use Juno's Gravity Science experiment to investigate the metals in the planet's atmosphere. Jupiter's atmosphere isn't as homogeneous as originally imagined, according ...

Early Solar System Was More Chaotic as Rocks, Boulders, and Planetesimals Constantly Collided, Says New Study
Astronomers believe asteroids have remained virtually unchanged since their genesis billions of years ago in the early solar system. A new research, which was based on fragments of asteroids that collided with Earth, provides a timeline for part of the mayhem.

Collision With Moon-Sized Body Likely Delivered Gold To Earth, Says Study
A large Moon-sized planetary body penetrated all the way down to the Earth's core during the early days of our home planet's formation, delivering in the process precious metals such as gold and platinum, suggests a new study.
