Could this asteroid be a piece of the Moon? A Chinese spacecraft is about to find out

The Moon is not the only natural object travelling through space alongside Earth. Several small asteroids travel around the Sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete a full orbit. Today, we know of eight such “quasi-moons” or…

James Webb telescope may have discovered a mysterious, never-before-seen substance on Pluto and Titan

A new study has identified a very specific wavelength of light missing from both Pluto and Saturn's largest moon, Titan. The surprising signal suggests that these worlds harbor an unknown molecule that has not yet been seen anywhere in the solar system or beyond.

3I/ATLAS mystery deepens: Discovered on July 1 last year, study suggest the cosmic visitor may be older than the Sun, Earth or any other object in our solar system

An Oxford PhD student, Matthew Hopkins, analyzed 3I/ATLAS, an interstellar object possibly older than our Sun. This visitor, the third confirmed, may originate from a star system formed around 7 billion years ago, originating from the galaxy's thick disc. Its chemical composition offers a unique glimpse into the early universe,…

Forget gold rush, diamonds rain on this planet, and it's located in our solar system

Deep within Uranus and Neptune, immense pressure and heat are transforming carbon into diamonds that rain down through the planets' interiors. Scientists at SLAC National Accelerator Laboratory recreated these conditions, confirming the rapid formation of nanodiamonds. This phenomenon could create vast diamond layers, influencing planetary heat escape and magnetic fields,…

These nearly invisible crystals could rewrite what we know about the early Solar System

Moon impact 3.5 billion years ago reveals hidden Solar System history through tiny mineral grains. The discovery shows asteroid bombardment continued long after the Late Heavy Bombardment period. Researchers found baddeleyite crystals inside lunar meteorite NWA 12593, dated nearly 3.486 billion years old. The evidence connects impacts on the Moon,…
