An illustration of a full moon in the night sky. The decision is in, then. After all, the Moon is not composed of green cheese. According to a detailed analysis released in May 2023, the Moon's inner core is a solid ball with a density akin to iron. Resolving this long-running controversy – is it solid...

Between late April and June 2024, the largest group of 13-year cicadas, known as Brood XIX, will emerge alongside a midwestern group of 17-year cicadas, Brood XIII. This phenomenon will impact 17 states, stretching from Maryland to Iowa and extending southward into...
The algae Braarudosphaera bigelowii has been found to have absorbed a cyanobacteria called UCYN-A, which may be a huge step forward for evolutionTyler Coale Scientists have witnessed a once-in-a-billion-year evolutionary event where two lifeforms merge, creating an organism with enhanced abilities. The last occurrence led to the emergence of plants on Earth. Known as primary endosymbiosis, this phenomenon...
Archival Chandra image of ACT-CL J0329. Credit: Sikhosana et al., 2024. A global team of astronomers conducted radio observations of the large galaxy cluster ACT-CL J0329.2-2330, uncovering a new radio halo within the cluster. The discovery was detailed in a research paper published on April 5 on the pre-print server arXiv. In fact, radio halos are...
After more than 20 years of planning, the LSST Camera module is now ready to be shipped to Chile for installation on the Simonyi Survey Telescope at the Vera C. Rubin ObservatoryJacqueline Ramseyer Orrell/SLAC National Accelerator Laboratory The SLAC National Accelerator Laboratory has unveiled the completion of the LSST Camera, boasting a remarkable 3,200-megapixel capacity....
Credit: Pixabay The landmark Paris climate accord sparked a rallying cry among developing nations: "1.5 to survive." This signifies the global goal of limiting temperature rise to 1.5 degrees Celsius (2.8 Fahrenheit) above preindustrial levels. However, it's anticipated that this threshold will be exceeded within the next decade, with global warming showing minimal signs of...

However, a newly developed map pinpoints optimal areas for reforestation, which can help in cooling the planet. Trees play a crucial role in absorbing carbon dioxide, and efforts to restore degraded woodlands or expand forested areas are important strategies in...
Russia and China aim to deploy a lunar nuclear reactor by 2035. Credit: gizmodo. In 2021, the Chinese and Russian space agencies forged a collaborative agreement to establish a research facility on the Moon. Recently, they unveiled plans to construct an automated nuclear reactor on the lunar surface, intended to energize the International Lunar Research...
a) Schematic: Metal foil inserted for internal heating and fast heat transfer to electrodes and electrolyte. Self-heating activated by switching off the connection between activation terminal and negative terminal. b) Evolution of cell voltage and temperature during activation at Vact = 0.4 V (inset) and subsequent 1C discharge at −20 °C. Battery temperature increases from −20 °C to 0 °C...
Astronomers have modeled the orbits of 1.3 million asteroids to check if any could bounce Apophis into an Earthbound pathDepositphotos In 2029, a sizable asteroid will pass by Earth at such proximity that it will be observable without telescopic aid. Fortunately, calculations of its trajectory suggest that there's no risk of impact in the next...
