The puzzling behavior of Titan’s atmosphere has been revealed by researchers at the University of Bristol for the first time. By analyzing data from the Cassini-Huygens mission, a joint venture between NASA, the European Space Agency (ESA), and the Italian Space Agency, the team have shown that the thick, hazy atmosphere of Saturn’s largest moon doesn’t spin in line with its surface, but instead wobbles like a gyroscope, shifting with the seasons.
A research team led by Prof. Wang Huiyuan from the University of Science and Technology of China (USTC) has made a groundbreaking discovery, identifying for the first time an exceptionally strong clustering pattern in diffuse dwarf galaxies. Their study, published in Nature, poses new challenges to the prevailing galaxy formation models within the Λ-Cold Dark Matter (ΛCDM) framework.
“[Deputy Nathaniel Ansay] never met a stranger and always had a huge smile on his face,” said Florence County Sheriff T.J. Joye. “He told me often how much he loved being a deputy”
The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it’s sensed light from a galaxy only 280 million years after the Big Bang, the most distant galaxy ever detected.
When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting states of matter, such as fractional quantum Hall liquids. These are exotic states of matter characterized by fractionalized excitations and the emergence of interesting topological phenomena.
The victims were leaving an event at the Capital Jewish Museum when the suspect approached the group and opened fire, Metropolitan Police Chief Pamela Smith said
An international team of astronomers reports the discovery of a new giant exoplanet around an M-dwarf star (GEMS). The newfound GEMS, designated TOI-5573 b, is comparable in size to Saturn and its mass is estimated to be 0.35 Jupiter masses. The findings were detailed in a research paper published May 13 on the arXiv preprint server.
Thomas Mascia claimed he was shot in the leg by a driver; instead, prosecutors say, he staged the scene of the incident by scattering shell casings, then shot himself at a park
Plasma—the electrically charged fourth state of matter—is at the heart of many important industrial processes, including those used to make computer chips and coat materials.
Members of the space exploration community are always coming up with novel ideas to solve problems that they view as holding back humanity’s expansion into the cosmos. One such problem that has become more noticeable of late, due to the failure of several powered lunar landers, is the difficulty of landing on the moon.
A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that characterizes the travel of these waves through magma, revealing how the relative proportions of crystals and bubbles influence wave velocity and waveform properties.
As the number of space travelers is increasing through commercial missions, it becomes more important to understand how space affects the human body.
The latest selfie by NASA’s Perseverance rover at Mars has captured an unexpected guest: a Martian dust devil.
Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of a comb. They serve as precise rulers for measuring time and frequency, and have become essential tools in applications such as lidar, high-speed optical communications, and space navigation. Traditional frequency combs rely on large, lab-based lasers. However, recent advancements have led to the development of chip-scale soliton microcombs, which generate ultrashort pulses of light within microresonators.
Southwest Research Institute scientists have discovered how solar activity affects the velocity distribution and evolution of helium pickup ions.
