Alpha Centauri May Have Sent Millions of Asteroids into the Solar System
A study proposes that Alpha Centauri could be contributing a significant number of asteroids to the solar system. Simulations indicate that around 50 objects from the neighboring star system may enter the Oort Cloud annually. While most pass through due to their high velocity, a few could travel inward. The frequency of such occurrences is expected...

NASA Supercomputer Finds Spiral Structure in the Oort Cloud’s Inner Region
A NASA supercomputer model suggests that the Oort Cloud’s inner structure forms a spiral, influenced by galactic tides. The Oort Cloud, a distant icy shell surrounding the solar system, has remained unobservable due to its vast distance. Researchers believe this finding could redefine understanding of how comets originate and interact with cosmic...

Over 1 Million Interstellar Objects Could Be Hidden in Our Solar System
A new study reveals that more than 1 million interstellar objects, each larger than the Statue of Liberty, may be residing in the Oort Cloud. These objects, believed to have originated from the Alpha Centauri system, were captured by the Sun’s gravity and are now part of our solar system. Unlike fast-moving interstellar visitors, these objects re...

Comet C/2024 G3 May Be Breaking Apart After Close Solar Encounter
New observations suggest that Comet C/2024 G3 (ATLAS) might be disintegrating after its close perihelion on January 15, 2025. Images reveal dimming of the comet’s coma and a bright streamer in its tail, indicating possible thermal stress from solar radiation. Experts speculate that structural cracks could be causing gas and dust to escape from th...

Asteroid That Triggered Dinosaur Extinction Was a Carbon-Rich C-Type Space Rock, Study Finds
Recent research has provided new insights into the asteroid that struck Earth 66 million years ago, causing a mass extinction event that led to the end of the dinosaurs. Scientists have now identified this impactor as a carbon-rich "C-type" asteroid, a type of space rock that likely originated in the asteroid belt between Mars and Jupiter.

Comet Tsuchinshan-ATLAS Heads Towards Earth, Will Be Visible With Naked Eye
A3 will make its closest approach to the Sun on October 10, 2024, and will be easily visible in northern hemisphere. In the southern hemisphere, it will be visible just after sunset.

Giant Comet Headed Towards Solar System, One of the Largest Ever Seen
A giant comet is heading toward the solar system. The comet, named Bernardinelli-Bernstein (BB), was discovered earlier this year and will reach its closest approach to the Sun in 10 years from now, around 2031.
