Climate change pushes Earth's systems to breaking points. Urgent action is needed to avoid cascading environmental and societal disasters.

New study challenges theory of life's extraterrestrial origin, pointing to volcanic lightning as the catalyst for life on Earth.

Explore the discovery of TOI-715b, a Super-Earth in the habitable zone, orbiting an M-dwarf star, unravelling secrets of exoplanets and potential life beyond

: Dive into the cosmic intrigue as an unprecedented dark hole on the sun sends powerful solar winds toward Earth. Explore the mysteries of coronal holes, the unexpected solar activity, and the enigma of this celestial drama challenging our understanding of the solar cycle.

Recent studies suggest that Earth's current oxygen-rich atmosphere, which has been a stable condition for millions of years, is not a permanent state. Instead, it is predicted to transition back to a methane-dominated atmosphere similar to its composition billions of years ago. While this atmospheric shift is not expected for another billion years, scientists anticipate a rapid and significant transformation once it commences.

A few decades ago, seismologists exploring the deep recesses of our planet stumbled upon a puzzling phenomenon—a slender layer just a few hundred kilometers thick, known as the E prime layer. For years, its origin remained shrouded in mystery. However, a recent breakthrough by an international team, including researchers from Arizona State University, has brought clarity to this long-standing puzzle.

A major transformation of global energy system is crucial to ensuring a safer and livable future. This transformation combines local and regional transitions from fossil fuels to renewable energy sources, widespread electrification, improvements in energy efficiency, and deployment in line with sustainable development, reveals the report Building a Nature-Positive Energy Transformation from the World Wildlife Fund (WWF) and the Boston Consulting Group (BCG).

Gas giant planets the size of Jupiter or larger can wreak havoc in young planetary systems, often pushing smaller, Earth-sized planets out of their original orbits, according to a recent study. These colossal gas giants, like Jupiter, are on a scale that's challenging to comprehend, with the volume of Jupiter accommodating as many as 1,300 Earths. This study uncovers how these giant planets act as agents of chaos, jeopardizing the prospects of life on their Earth-like neighbours.

In the Eastern Sierra Nevada mountains of California, a dormant supervolcano known as the Long Valley Caldera has been dormant for an astonishing 760,000 years. However, recent signs of unrest are raising questions about its potential to unleash a catastrophic event.

Human activities make the Earth's air, soil and freshwater saltier and this continued salt accumulation poses an "existential threat" to the environment if current patterns persist, said a recent scientific review.
