A new isotopic study reveals that Theia—the Mars-sized body that struck Earth 4.5 billion years ago to form the Moon—likely originated in the inner Solar System, close to Earth’s birthplace. By comparing heavy-element isotope ratios in lunar rocks, Earth samples, and meteorites, researchers found identical signatures, showing both worlds formed from the same inn…

NASA’s Fermi Gamma-ray Space Telescope has detected a faint halo of high-energy gamma rays around the Milky Way’s centre—matching predictions for dark-matter annihilation. The finding, reported by Professor Tomonori Totani, could represent the first direct glimpse of dark matter, but scientists caution that alternative explanations remain and independent confirm…

Researchers at the University of Chicago have created new materials that make OLED displays fully stretchable. Their key advance is an aluminium electrode embedded in a gallium–indium alloy, allowing it to “crackle” and self-heal under strain as liquid metal fills emerging gaps. Alongside this, a newly designed stretchy conductive polymer maintains electrical pe…

A new study has identified the primary force behind Venus’s extreme superrotating atmosphere: a once-per-day thermal tide driven by solar heating. Using data from Venus Express and Akatsuki along with circulation models, researchers show that this daily tide transports most of the momentum that accelerates cloud-top winds to speeds over 100 metres per second. The re…
