Ancient landscape formed by rivers revealed deep under Antarctic ice

Antarctica has not always been a desolate land of ice and snow. Earth's southernmost continent once was home to rivers and forests teeming with life. Using satellite observations and ice-penetrating radar, scientists are now getting a glimpse of Antarctica's lost world. Researchers said on Tuesday they have detected buried under the continent's ice sheet a vast ancient landscape, replete with valleys and ridges, apparently shaped by rivers before being engulfed by glaciation long ago.

China's youngest-ever crew of astronauts heads to space station

The youngest-ever crew of Chinese astronauts departed for China's space station on Thursday, paving the way for a new generation of "taikonauts" to advance the country's space ambitions in the future. The spacecraft Shenzhou-17, or "Divine Vessel", and its three passengers lifted off atop a Long March-2F rocket from the Jiuquan Satellite Launch Centre in northwest China.

Scientists identify molten layer deep within interior of Mars

Seismic waves generated by a meteorite impact on the other side of Mars from where NASA's InSight lander sits have provided new clues about the Red Planet's deep interior, prompting scientists to reappraise the anatomy of Earth's planetary neighbor. The new seismic data indicates the presence of a hitherto unknown layer of molten rock surrounding a liquid metallic core - the planet's innermost component - that is smaller and denser than previously estimated, researchers said on Wednesday.

Scientists unveil recreation of sacrificed Inca maiden in Peru

The reconstructed head and torso of a young girl likely sacrificed to appease Incan gods was unveiled in Peru on Tuesday, with three-dimensional scans of her mummy helping produce the lifelike recreation more than 500 years after her death. Scientists from both Peru and Poland used digital scans of her mostly well-preserved mummy, which was found in 1995 inside an Inca-era funerary bundle near the summit of the Ampato volcano outside Arequipa, in Peru's south.

Factbox-Partner nations on China's lunar research station programme

Belarus this week joined China's International Lunar Research Station (ILRS) programme, the third country to sign up this month for a plan to eventually set up a permanently inhabited outpost on the moon's south pole. Earlier in October, Pakistan and Azerbaijan joined the ILRS, a project jointly initiated by China and Russia in 2021 and widely seen as a rival to the U.S.-led Artemis programme.
