Study Traces Moon-Forming Impact to an Inner Solar System Neighbour Named Theia
A new isotopic study reveals that Theia—the Mars-sized body that struck Earth 4.5 billion years ago to form the Moon—likely originated in the inner Solar System, close to Earth’s birthplace. By comparing heavy-element isotope ratios in lunar rocks, Earth samples, and meteorites, researchers found identical signatures, showing both worlds form...

Astronomers Detect Hints Of Hidden Earth-Sized Planet Beyond Neptune
Astronomers propose the existence of ‘Planet Y’, a hidden Earth-size planet that may orbit closer than the theorized ‘Planet Nine’. Based on Kuiper Belt object patterns, the study suggests a rocky world influencing orbital tilts. Experts remain divided, but upcoming sky surveys could soon confirm or rule out its existence.

Opinion | When the Dragon Tightens Its Talons: China's New Techno-Mineral Manoeuvre
China's reigning position in the rare earth supply chain, nay, the critical minerals chain, is of alarming concern for all, including major western powers like the USA and developing economies like India.

Not Like Venus Or Mars, Distant Exoplanet May Have Atmosphere Like Earth's
A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST) suggest. It is part of a group of planets orbiting a star called TRAPPIST-1, about 40 light-years away from Earth.

NASA Missions Uncover a Diverse Galaxy of Super-Earths, Raising New Questions About Planetary Evolution
Super-Earths are among the most common planets in the galaxy, yet none exist in our solar system. Larger than Earth but smaller than Neptune, they range from ocean-covered worlds to scorched, atmosphere-less rocks. Some orbit within habitable zones, making them prime candidates for life. NASA’s Kepler and TESS missions, along with upcoming telesc...

Meteorite From Outer Solar System Challenges Planet Formation Timeline in Early Solar System
A meteorite from the outer solar system may upend long-held beliefs about planetary formation. New research shows rocky planets like Earth may have formed at the same time as those beyond Jupiter. The findings challenge previous models and suggest a more synchronised origin for rocky worlds across the solar system, with major implications for plane...

Rise In Greenhouse Gas Release Causing More Extreme Weather, Scientists Warn
Humans are on track to release so much greenhouse gas in less than three years that a key threshold for limiting global warming will be nearly unavoidable, according to a study to be released Thursday.

Oceans Were Once Green, Could Change Colour Again: Study
Nearly three fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth's oceans were once green, in a study published in Nature.
