This article from Die Welt, published on July 18, 2026, explores the hypothetical scenario of the moon suddenly disappearing, using NASA and DLR expert insights. It explains that the moon stabilizes Earth's axial tilt at 23.5 degrees, which creates seasons; without it, the axis could fluctuate wildly, leading to extreme seasons or ice ages. Tides would weaken dramatically as the moon is the primary driver, disrupting coastal ecosystems and ocean currents that distribute heat globally. The moon's gravity has also slowed Earth's rotation over billions of years to 24-hour days; if it vanished, this braking would stop, though the sun would eventually slow Earth further over billions of years. Immediate effects would include darker nights and weaker tides, while long-term changes to climate and day length would unfold over millennia.

A new study presented at the European Geosciences Union 2026 General Assembly in Vienna reveals that enigmatic crown-like surface formations on Venus, known as coronae, are crucial for understanding the planet's deep interior. Lead researcher Anna Gulcher from the University of Freiburg utilized decades-old radar data from NASA's Magellan spacecraft to create advanced 3D models of these structures. The research indicates that coronae are not formed by a single mechanism but reflect a spectrum of dynamic processes, likely driven by mantle convection and hot material plumes rising from the planet's interior. The study identified potential warm mantle upwellings beneath 52 of the 741 cataloged coronae, suggesting that tectonic activity on Venus may be more widespread than previously detected by gravity data alone. These findings help decipher Venus's geodynamic regime and offer insights into whether similar processes occurred on early Earth. Unlike Earth, where water facilitates plate tectonics and carbon recycling, Venus's dry environment likely limited such activities. This research underscores the importance of upcoming missions to gather in situ data to further solve the conundrums of Venus's geological history and its divergence from Earth's evolutionary path.

A new study published in the journal Icarus challenges the hypothesis that Earth's co-orbital asteroids, such as Kamo'oalewa, are fragments blasted from the Moon. While spectral analysis previously suggested these objects matched lunar silicates, researchers Elisa Alessi and Robert Jedicke used supercomputer simulations to model the orbital dynamics of debris ejected from the lunar surface. Their findings indicate that the energy required to launch a rock into a stable co-orbital path is immense, making a lunar origin statistically unlikely, with a probability of only 4.3% for objects larger than 10 meters. In contrast, simulations using the NEOMOD3 model suggest the main asteroid belt is a far more probable source, potentially supplying around 1,600 such co-orbitals. The debate may soon be resolved by China's Tianwen-2 mission, which launched in May 2025 and is currently approaching Kamo'oalewa to collect surface samples. If the samples prove to be lunar material, it would necessitate a significant revision of current understanding regarding lunar impact mechanics and crater-scaling laws.

Scientists have discovered traces of stardust trapped in Antarctic ice, dating between 40,000 and 81,000 years old. The findings, published in Physical Review Letters, identify the presence of iron-60, a rare isotope formed exclusively during supernova explosions. Because this isotope has a relatively short half-life of 2.6 million years, its presence confirms an extraterrestrial origin rather than terrestrial formation. The research team, led by astrophysicist Dominik Koll from the Helmholtz Center Dresden-Rossendorf, analyzed 295 kilograms of ice samples collected under the European Antarctic Ice Core Project (EPICA). These ice cores serve as vertical time capsules, recording Earth's passage through the Local Interstellar Cloud. The data indicates that the Solar System has been moving through this region of gas, dust, and plasma for at least 80,000 years. Furthermore, the study reveals that the interstellar cloud was less dense in the past compared to recent decades, as evidenced by lower iron-60 concentrations in older ice layers.
