Researchers from the University of Oxford have uncovered evidence that Mars once hosted enormous, Earth-like magmatic systems deep beneath its surface—despite the planet lacking the plate tectonics long thought necessary ...
The Gaia mission has allowed researchers to understand the motions of stars like never before, even revealing possible interactions between our solar system and nearby stars. Planetary Science Institute Senior Scientist Nathan ...
New research led by Curtin University and QUT (Queensland University of Technology) has revealed that repeated asteroid impacts may have been the dominant force shaping early Earth, delivering vast amounts of heat into the ...
An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration ...
Life on Earth took a long evolutionary journey that eventually created us, the purportedly intelligent species that dominates the planet. But there was no grand plan or design, only happenstance, nature and luck. Life on ...
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's ...
On Earth, garnet is best known as the fiery red January birthstone—popular in jewelry since the Bronze Age and valued highly by ancient Egyptians.
