Plasma falls on the Sun. Plasma falls have been seen on the sun many times before, yet researchers still don't fully understand them. One big mystery is how fast they fall. The sun's gravity is powerful, but not powerful enough to pull the plasma down so quickly through the thicket of solar magnetic fields. Nuclear engineers would like to figure out how this happens, because it also happens on a smaller scale in fusion reactors, frustrating their efforts to sustain an energy-producing reaction.

The three-body problem is a classic and notoriously difficult question in physics and mathematics. It asks: How do three objects, such as stars, planets, or moons, move under the influence of each other’s gravity? Unlike the simpler two-body problem, which has precise and predictable analytical solutions (like the Earth orbiting the Sun in an ellipse), the three-body problem quickly becomes chaotic and unpredictable. This complexity arises because each object's motion constantly affects, and is affected by, the other two. These gravitational interactions form a tangled and unstable system. In fact, there's no general formula that can solve all three-body scenarios exactly. This was first demonstrated in the 19th century by Henri Poincaré, whose work laid the foundations for chaos theory. While exact solutions remain elusive, scientists have discovered certain special cases where the motion is stable or periodic. One well-known example is the Lagrange points, where three bodies can maintain a stable triangular configuration. However, such neat solutions are rare. Today, thanks to powerful computers, researchers can simulate three-body systems with remarkable accuracy, helping us study triple-star systems, exoplanets, and asteroid dynamics. Yet even small changes in the starting conditions can lead to dramatically different outcomes, highlighting the sensitive dependence on initial conditions that defines chaotic systems. The three-body problem is actually a specific case of the broader n-body problem, where n can be any number of interacting bodies. As n increases, the complexity and unpredictability rise even further. The three-body problem serves as a vivid example of how simple laws of nature, like Newton’s law of gravity, can produce behavior that is intricate, unexpected, and profoundly difficult to predict.

NASA’s Voyager spacecraft revealed a remarkable discovery at the edge of our solar system: a vast region of superheated plasma, reaching temperatures between 30,000 and 50,000 Kelvin. This area, encountered by both Voyager 1 and Voyager 2 as they crossed the heliopause, the boundary where the solar wind is stopped by the pressure of interstellar space, is sometimes referred to as a “wall of fire.” Despite these extreme temperatures, the region poses no danger to the spacecraft because of its incredibly low particle density; the high temperatures reflect particle speed, not heat felt as we experience it. Scientists believe this heat is caused by plasma compression and magnetic reconnection, where magnetic fields release large amounts of energy. Voyager’s findings revealed that the boundary of the heliosphere is far more complex and energetic than previously thought. Even decades after their launch, the Voyager probes continue to offer groundbreaking insights into the dynamic and mysterious frontier between our solar system and interstellar space.

A new theory suggests that time might be an illusion created by quantum entanglement. According to this theory, changes over time are perceived only because objects are entangled with clocks, making the universe appear static to an external observer.

These two bright objects are Earth and the Moon, as observed from the orbit of Mercury. The image was acquired by NASA's MESSENGER (Mercury Surface, Space Environment, Geochemistry, and Ranging) spacecraft on May 6, 2010. At the moment this image was captured, the MESSENGER spacecraft was ~ 180 million km from Earth. This distance is notably greater than the typical separation between Earth and Mercury, attributable to the varying orbital positions of the two planets around the Sun at the time of the image acquisition. The MESSENGER team was searching for small rocky objects called vulcanoids, believed to be orbiting between Mercury and the Sun. Happily the spacecraft also recorded this remarkable view. From the perspective of the MESSENGER spacecraft, Earth and the Moon were located near the boundary of the constellations Libra and Scorpius. ©️ @JHUAPL / @carnegiescience
