A new surface atlas of Phobos will help MMX mission collect its samples

Thanks to JAXA, the Japan Aerospace Exploration Agency, and its sample-return capabilities, we're on the cusp of receiving our first sample from the Martian system—not from Mars itself, but from its largest moon, Phobos. ...

How atmospheric events at the top of the world could have triggered two devastating California floods

In early 2017 and 2023, California experienced two catastrophic and record-breaking floods that caused billions of dollars in damage, triggered mudslides and forced thousands of people to evacuate. Why this happened left ...

'Fingerprints' inside the sun could reveal if it once swallowed a planet

It is thought the sun may have engulfed a super-Earth-sized planet early in its history. Now, a new study has gone a step further, suggesting that such an event may have left behind detectable clues inside the sun that could ...

Mercury is shrinking more than we thought

Mercury's surface is riddled with wrinkles, evidence of a once-larger planet that has shrunk over time. A new study finds that Mercury may have contracted 10% to 30% more than previously thought—a loss of nearly 12 miles ...

Beryllium signal identifies stars that have swallowed rocky planets

An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in ...

The Anthropocene was rejected as a geological epoch—but the idea is still changing how we see the world

The Anthropocene became part of the zeitgeist after Nobel laureate Paul Crutzen launched the idea in 2000. This is the notion that a crescendo of human impacts has recently propelled Earth out of the relatively stable climatic ...

A new mission could rendezvous with Halley's Comet in 2061

Halley's Comet captures the imagination in a way that few other astronomical objects do. When it last made its approach toward the sun (admittedly when this author, who is now middle-aged, was 1 year old in 1986), humanity ...

Early Earth's auroral belts may have formed a natural ion-beam reactor for prebiotic chemistry

We usually think of auroras as beautiful lights in the night sky. I see them as visible traces of a connection between the sun, Earth's magnetic field and the atmosphere. This led me to an origin-of-life question: Could the ...
