A rogue planet is a planetary-mass object that does not orbit a star but instead floats freely in space. Unlike regular planets, which orbit stars, rogue planets are isolated and can still grow by accreting gas and dust from their surroundings, as observed in the case of Cha 1107-7626.

The rogue planet Cha 1107-7626 is surrounded by a disk of gas and dust from which it accretes material. This accretion process, similar to that seen in young stars, allows the planet to grow even without a parent star. Strong magnetic fields may trigger intense growth spurts, causing the planet to consume up to six billion tons of matter per second.

John Ternus is Apple's Senior Vice President of Hardware Engineering, responsible for leading the development of key products like iPhones, iPads, Macs, and AirPods. He has been a key figure in Apple's transition to Apple silicon for Macs and is considered a potential successor to Tim Cook as CEO.

John Ternus is being highlighted due to his strong track record in hardware engineering and his potential to succeed Tim Cook as CEO. His ability to bridge hardware and software teams and his managerial skills have earned him respect within Apple, making him a likely candidate for the top role.

An all-time high (ATH) for Bitcoin refers to the highest price that Bitcoin has ever traded at in its history. It marks a significant milestone indicating peak demand and market confidence. ATHs often attract increased media attention and investor interest, serving as a benchmark for future price trends and market performance.

Bitcoin's surge to $125,750 was driven by macroeconomic uncertainty, seasonal trends such as historically strong performance in October ('Uptober'), increased institutional interest, and bullish market indicators. Additionally, renewed inflows into Bitcoin exchange-traded funds and a broader risk rally amid events like the U.S. government shutdown supported the price increase.

Space heaters draw high currents, often around 1,500 watts or more, which can cause low-quality or small-gauge extension cords to overheat and melt their insulation, potentially leading to fires. Therefore, space heaters should always be plugged directly into wall outlets to ensure safety.

When buying a space heater, look for models that have a tip-over safety switch that automatically shuts off the heater if it tips over, a thermostat to regulate temperature, a long power cord to keep the heater away from combustibles, a sturdy handle for safe movement, and certification marks such as Underwriter’s Laboratories (UL) indicating the heater has been tested for safety.

The iPad Air (2025) features the more powerful M3 chipset, available in 11-inch and 13-inch sizes, supports Apple Intelligence features, Stage Manager, and has better display and accessory support. It is suited for professionals, creatives, and students needing more power. The base 11th Gen iPad uses the A16 chip, has a 10.9-inch LCD display, supports only the first-generation Apple Pencil, and lacks advanced features like Stage Manager and Thunderbolt. It is ideal for casual users, students, and families due to its affordability and sufficient performance for everyday tasks.

Yes, the iPad Air (2025) is considered the best iPad for students in 2025 because it balances power, features, and price effectively. It offers the M3 chip for strong performance, supports advanced multitasking features, and comes in two sizes. While it is more expensive than the base iPad, it is significantly more affordable than the iPad Pro models, making it a great option for students and professionals who need more than basic functionality without the premium cost.

The 'cosmic fog' refers to a surprisingly dense and slow wind of hot matter blowing from the accretion disk around the neutron star GX13+1. This wind is composed of material being pushed away from the neutron star's surface as it accretes matter from a companion star. Unlike faster winds seen near supermassive black holes, this wind travels at about 1 million km/h, much slower than expected, revealing new insights into how such cosmic winds form and behave.

Temperature plays a key role in driving the behavior of cosmic winds because it affects the density and speed of the outflowing material. XRISM's observations showed that the wind from neutron star GX13+1 is thick and slow, indicating that temperature differences lead to distinct wind characteristics compared to those near supermassive black holes, where winds are faster and less dense. This finding helps scientists understand the physical processes governing how matter is expelled from accretion disks in different cosmic environments.

The Ramón Sánchez-Pizjuán Stadium is the home stadium of Sevilla FC, located in Seville, Spain. It has a seating capacity of approximately 42,700 to 45,500 spectators, making it one of the largest stadiums in Spain and Andalusia. The stadium is historically significant, having hosted major events such as the 1982 World Cup semi-final and the 1986 European Cup Final. Its atmosphere and size make it a challenging venue for visiting teams like Barcelona, adding importance to the match in the context of La Liga competition.

The match is pivotal because Barcelona faces a challenging test of their title credentials by playing away at Sevilla's home ground, the Ramón Sánchez-Pizjuán Stadium. Success in this fixture is crucial for Barcelona to maintain or strengthen their position in the La Liga title race, as Sevilla is a strong opponent and the stadium environment is known for being demanding for visiting teams.

The far side of the Moon has a thicker crust, more mountains and craters, and fewer volcanic lava plains compared to the near side. This difference extends beneath the surface, with the far side's mantle showing temperatures about 100 °C lower. This thermal asymmetry may be caused by an uneven distribution of heat-producing elements like uranium, thorium, and potassium in the Moon's interior, which affects radioactive decay and heat generation.

Scientists analyzed rock samples returned by China's Chang’e 6 mission from the Moon's far side and compared them with samples from the near side collected by NASA's Apollo missions. By studying the mineral composition and using computer simulations, they estimated the crystallization temperature of the far side lava to be about 1,100 °C, roughly 100 °C cooler than near side samples. This method provided the first direct evidence of a temperature difference in the Moon's mantle.
