"The Violent Origins of Pluto's Heart: Astrophysicists Uncover Cosmic Collision"

An international team of astrophysicists has solved the mystery of Pluto's heart-shaped feature, attributing it to a giant and slow oblique-angle impact with a planetary body over 400 miles in diameter. The impact formed Sputnik Planitia, a region predominantly filled with nitrogen ice, and the study suggests that Pluto's inner structure is different from previous assumptions, indicating no subsurface ocean. The findings shed new light on Pluto's early history and offer a novel origin hypothesis for its unique surface feature.

"Unraveling the Enigma of Pluto's Heart-Shaped Surface Feature"

An international team of astrophysicists has solved the mystery of the heart-shaped feature on Pluto's surface, attributing it to a giant and slow oblique-angle impact. Using numerical simulations, the team determined that a collision with a planetary body about 700 km in diameter formed the feature, known as Sputnik Planitia. The study also suggests that Pluto's internal structure is different from previous assumptions, indicating no subsurface ocean. This research sheds new light on the origins of Pluto and its unique surface features.

Unraveling the Mysteries of Gravitational Wave Collapse

A recent study by an international research collaboration has resolved long-standing puzzles in the gravitational collapse of gravitational waves. The study found agreement among three independently conducted numerical simulations, shedding light on critical phenomena and the properties of general relativity. The researchers discovered that the collapse of gravitational waves does not exhibit universality, but approximate self-similarity. The findings could lead to further studies and a better understanding of the nature of critical collapse and the formation of black holes.

The Emergence of Order in Flexible Beam Clusters.

A study on the behavior of compressed elastic beams shows that the emergence of order is determined by geometry, not complex forces. The researchers fixed flexible plastic beams vertically between two horizontal plates and squeezed them together, causing the beams to bend and come into contact with one another. The order increased with compression and depended mainly on the ratio of the uncompressed beam height to the compressed beam height. The researchers also observed a set of phenomena that seemed to govern the emergence of order, including "clump-hole annihilation." The results could be useful for designing flexible materials and understanding interactions among flexible structures in nature.
