Scientists Trace Rare Cosmic Outburst to a Massive Planetary Collision Around Gaia20ehk
Astronomers have reported evidence of two planets colliding around a distant Sun-like star, Gaia20ehk, located about 11,000 light-years away. The star's light output remained steady until 2016, when it exhibited three minor dimming events; by 2021, the light curve reportedly "went completely bonkers." Follow-up infrared observations revealed a burs...

Dramatic Planet Collision In Distant Galaxy May Explain How Earth's Moon Was Formed 4.5 Billion Years Ago
Scientists observe a dramatic collision between two planets, offering insights into the formation of Earth's Moon 4.5 billion years ago.

New ALMA Images Reveal Complex Rings Left Behind by Planet Formation
Astronomers used ALMA to capture unprecedented images of young exoplanetary systems. The ARKS survey mapped 24 debris disks, revealing rings, gaps and collisions that trace planetary evolution. These snapshots expose chaotic transitional stages, helping scientists understand how newborn planets mature into stable systems like our own Solar System t...

Hubble Observations Turn Exoplanet Into Dust; Reveal Rare Double Asteroid Impact in Nearby System
NASA’s Hubble Space Telescope has revealed that a vanished exoplanet near the star Fomalhaut was never a planet at all. Scientists discovered two rare, violent collisions between asteroid-sized bodies, producing glowing debris clouds that briefly mimicked planets. The findings offer a rare glimpse into how planetary systems evolve and how mislead...

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.

Mars' Interior Holds Evidence Of Violent Early History, NASA Scientists Confirm
NASA scientists have discovered massive fragments of ancient planetary collisions buried deep in Mars' mantle, using seismic data from the InSight lander.

Mars Dust Devils May Spark Lightning, Might Pose Risks to Rovers: Study
A new computer-modeling study reveals that dust devils on Mars—swirling columns of dust and air—may become electrically charged enough to spark lightning-like discharges. Led by researcher Varun Sheel, the study simulates how dry Martian conditions and frictional collisions between dust grains can generate strong electric fields inside these vo...

Asteroid Vesta May Be a Fragment of a Lost Planet, Say Scientists
Vesta, once believed to be a stalled protoplanet, may be a fragment of a long-lost differentiated planet. Using refined gravity data from NASA’s Dawn mission, scientists found it lacks a dense core, suggesting it was ejected during a primordial impact. This revised view may apply to other asteroids and reshape planetary formation theories.
