Sep. 22, 2022 —Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a 'hot spot' orbiting Sagittarius A*, the black hole at the centre of our galaxy. The ...
Mar. 3, 2023 —When asteroids suffer natural impacts in space, debris flies off from the point of impact. The tail of particles that form can help determine the physical characteristics of the asteroid. NASA's ...
June 5, 2023 —A delicate tracery of dust and bright star clusters threads across this image from the James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, ...
Sep. 19, 2022 —In classical models of stellar evolution, so far little importance has been attached to the early evolution of stars. Scientists now show that the biography of stars is indeed shaped by their early ...
July 7, 2021 —A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical ...
Feb. 4, 2022 —The Standard Model of Cosmology describes how the universe came into being according to the view of most physicists. Researchers have now studied the evolution of galaxies within this model, finding ...
Aug. 17, 2023 —磁星是最强的磁铁the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they ...
Sep. 24, 2020 —Gravity can accelerate the homogenization of space-time as the universe ...
June 28, 2021 —Scientists have discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. While they have been theorized for 40 years, real-world examples have ...
Mar. 28, 2022 —物理学家知道阿布t the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and ...
