Scientists have likely detected a so-called marsquake — an earthquake on Mars — for the first time, The National Aeronautics and Space Administration (NASA) announced on Tuesday.


On April 6, NASA's InSight lander picked up a gentle rumble on the red planet, measuring a faint signal.

The rumble sounded like soft wind, but scientists believe it came from seismic activity within the planet.

The Paris Institute of Earth Physics' Philippe Lognonne, who leads the experiment, said it was long-awaited proof that Mars is seismically active.

"We've been waiting months for a signal like this," Lognonne said in a statement.

Mars is much less geologically active than Earth and lacks the tectonic plates that cause most earthquakes.

InSight's lead scientist, Bruce Banerdt of NASA's Jet Propulsion Laboratory in Pasadena, California, said the result was the continuation of work started by the Apollo moonwalkers nearly a half-century ago, who placed seismometers that measured thousands of moonquakes.

For Mars, "we've been collecting background noise up until now, but this first event officially kicks off a new field: Martian seismology!" Banerdt said in a statement.

The field of Martian seismology could shed light on how rocky planets formed.

The tremors were picked up by sensors in the Martian lander, in one of the more successful experiments being carried out. The lander is the first spacecraft designed specifically to study the deep interior of a distant world.

The temperature of the Arctic matters to the entire world: it helps to keep the global climate fairly cool. Scientists now say that by 2035 there could be an end to Arctic sea ice.

My name is Arkilaus Kladit. I'm from the Knasaimos-Tehit tribe in South Sorong Regency, West Papua Province, Indonesia. For decades my tribe has been fighting to protect our forests from outsiders who want to log it or clear it for palm oil. For my people, the forest is our mother and our best friend. Everything we need to survive comes from the forest: food, medicines, building materials, and there are many sacred sites in the forest.

Overthinkers are people who are buried in their own obsessive thoughts. Imagine being in a large maze where each turn leads into an even deeper and knottier tangle of catastrophic, distressing events — that is what it feels like to them when they think about the issues that confront them.
