This stunning image from NASA’s Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation Cygnus, the Egg Nebula features a central star obscured by a dense cloud of dust—like a “yolk” nestled within a dark, opaque “egg white.” Only Hubble’s sharpness can unveil the intricate details that hint at the processes shaping this enigmatic structure.
Scientists from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (CAS), the CAS Aerospace Information Research Institute, and other institutions, have revised the decades-old lunar crater chronology model, using samples collected from the far side of the moon by China’s Chang’e-6 mission and complementary remote sensing imagery.
NASA is now aiming to launch four astronauts to the International Space Station (ISS) on Friday, in another delay over weather conditions, the U.S. agency announced Tuesday.
Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of civilizations beyond Earth, have published new results from the Breakthrough Listen Galactic Center Survey, one of the most sensitive radio searches ever conducted for pulsars in the dynamically complex central region of the Milky Way. The study, led by recent Columbia Ph.D. graduate Karen I. Perez, was published in The Astrophysical Journal.
A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without losing energy to heat. Described in Nature Physics, the work, led by Xiaodong Xu at the University of Washington, marks the first demonstration of a “dissipationless fractional Chern insulator,” a long-sought state of matter with promising implications for future quantum technologies.
Phoenix PD officers responded to 911 calls reporting shots fired to find a man pinning down another man; one officer fired shots, fatally wounding the man who disarmed the suspect
Officers say California Assembly Bill 1627 unfairly punishes individuals for prior lawful employment rather than evaluating conduct, qualifications and accountability
Judge Christina Snyder ruled that the mask ban as it was enacted did not also apply to state law enforcement authorities, discriminating against the federal government
When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing kinetic energy in the process. But in some materials, heat can travel in a different way, flowing like water in a pipeline that—at least in principle—can be forced to move in a direction of choice. This second regime is called hydrodynamic heat transport.
In a new study published in Physical Review Letters, researchers used machine learning to discover multiple new classes of two-dimensional memories, systems that can reliably store information despite constant environmental noise. The findings indicate that robust information storage is considerably richer than previously understood.
In a new study, researchers say that nonbiological sources they considered could not fully account for the abundance of organic compounds in a sample collected on Mars by NASA’s Curiosity rover. The paper is published in the journal Astrobiology.
The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy (MPIfR) used data from the Atacama Large Millimeter/submillimeter Array (ALMA) to shed light on this open question of galaxy formation. They studied one of the most spectacular galaxy aggregations in great detail and published their results in the current issue of The Astrophysical Journal.
Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. While some past studies gathered indirect hints of its existence, dark matter has never been directly observed; thus, its composition remains a mystery.
Using NASA’s Fermi Gamma-ray Space Telescope, Chinese astronomers have observed a gamma-ray binary system known as PSR J2032+4127. Results of the new observations, published February 3 on the arXiv preprint server, shed more light on the orbital parameters of this binary, which could help us better understand its nature.
In a tightly controlled manufacturing hangar west of Paris, workers put the finishing touches on an enormous silver-colored engine. In just a few days, a similar machine will help propel the most powerful version of Europe’s Ariane 6 rocket yet, flying for the first time with four boosters.
