Classic Moon-formation simulations typically produced a ring of debris that assembled over months or years after a Mars-sized world struck early Earth. But simulations published in September 2026 that included temperature-dependent rock strength found that, under certain conditions, a coherent Moon-sized satellite could emerge in roughly five hours.

14+ hour, 52+ min ago   (1286+ words) A September 2026 impact study found that strength retained by hot, partly solid rock can redirect Theia’s rebound and capture a coherent satellite within hours. By Terra Daily Editorial Team · Editorial process Published September 13, 2026 For decades, the standard computer version of…...

Activists question treaty power to protect high seas

7+ mon, 2+ week ago   (415+ words) The authors contend that the rapid warming of the ocean, driven by climate change, is already fuelling extreme weather and placing marine life under mounting stress. They highlight compounding pressures including acidification, pollution, plastics and industrial activities such as deep…...

Geoscientists use satellite to determine not the shape of water, but how water shapes land

7+ mon, 2+ week ago   (427+ words) Virginia Tech geoscientists are using the same satellite to ask a related question: How is water shaping the land? "We wanted to show how the satellite could be used in ways that it wasn't primarily designed for," said postdoctoral associate…...

Lunar soil study limits late meteorite role in supplying Earth oceans

7+ mon, 2+ week ago   (853+ words) Los Angeles CA (SPX) Jan 26, 2026 - A long standing idea in planetary science is that water rich meteorites arriving late in Earth history could have delivered a major share of the planet's water. A new study that mines the Moon's imp…...

Slow orbital wobble patterns drive ancient greenhouse climate swings

7+ mon, 4+ week ago   (413+ words) Because Earth's rotation axis is tilted relative to its orbital plane, regions outside the tropics experience a single annual peak in solar radiation, near the local summer solstice. By contrast, tropical latitudes see two annual maxima in solar radiation near…...

Hunga eruption reshaped stratospheric water and ozone with limited climate cooling

8+ mon, 1+ week ago   (334+ words) "This assessment shows how Hunga's water-rich plume reshaped the stratosphere in ways not seen before. It underscores the importance of sustained observations and advanced modelling, and the value of international scientific collaboration through WCRP in delivering robust climate insights," said…...

Ancient giant shark fossils reveal early mega-predator dominance in Australian seas

9+ mon, 2+ week ago   (172+ words) Modern sharks trace their origins to the Age of Dinosaurs, with the oldest known lamniform fossils dated to about 135 million years ago. These early sharks started small, around 1 meter in length, but later produced larger species including the Megalodon, which…...
