Earth’s rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet’s molten youth using advanced quantum mechanical simulations, revealing nitrogen’s secret: under extreme pressure, it chose to hide in the iron core 100 times more than the mantle. This solved why Earth’s volatile ratios involving nitrogen look odd. The findings suggest the necessary ingredients for developing a habitable world may have been settled in the early Earth.

A team at Nagoya University in Japan has revealed new insights into the motion of massive stars in the Small Magellanic Cloud (SMC), a small galaxy neighboring the Milky Way. Their findings suggest that the gravitational pull of the Large Magellanic Cloud (LMC), the SMC’s larger companion, may be tearing the smaller one apart. This discovery reveals a new pattern in the motion of these stars that could transform our understanding of galaxy evolution and interactions.

Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence is confirmed it would "effectively break current models of galaxy numbers and evolution". The possible galaxies may also provide the missing piece of the puzzle for the energy generation in the universe in infrared light. That's because their combined light would be enough to top-up the energy budget of the universe to the maximum we observe, effectively accounting for all remaining energy emission at these long wavelengths.

Before humans can colonize the moon or Mars, scientists and engineers must first develop techniques for building permanent structures and pressurized habitats in harsh, thin-atmosphere and low-gravity environments.

Dr. Wei Li, an assistant professor of mechanical engineering in the Erik Jonsson School of Engineering and Computer Science at The University of Texas at Dallas, is developing a virtual lunar welding platform to troubleshoot assembling large structures in such conditions.

Chinese scientists have discovered that the Moon’s mantle contains less water on the lunar farside than on the nearside, based on analysis of basalts collected by the Chang'e-6 (CE6) lunar mission.
