迅速增长的卫星群引起了学界的强烈关注。卫星的反射光肉眼可见，对于专业望远镜而言非常明亮。这些轨迹已经影响了全电磁波谱的天文图像，在运行和校正方面付出了显著的成本。 与普遍看法相反，卫星轨迹不仅影响地面天文台，还影响哈勃太空望远镜等太空天文台。然而，目前在轨卫星数量只是未来十年计划发射卫星的一小部分（不到3%）。 研究组基于电信行业提出的卫星群计划，对一系列国际近地轨道望远镜的卫星轨迹污染程度进行了 ...

The European Organization for Nuclear Research (CERN) has shed light on the structure of "exotic" particles. These particles ...

The CMS collaboration reports the first measurement of the quantum properties of a family of tetraquarks that was recently ...

To fully address how quarks get decayed and excited, how particles are formed and generated, and how they interact and transmute, a two-flavor (up & down) multi-excitation (ground & excited) quark ...

Top quarks and antiquarks have been detected in heavy-ion collisions at the Large Hadron Collider, showing that all six quark flavors were present in the Universe’s first moments. American Institute ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

"With evidence that quarks and gluons are entangled, this picture has changed. We have a much more complicated, dynamic system." When you purchase through links on our site, we may earn an affiliate ...

Breakthroughs are like London buses. You wait a long time, and three turn up at once. In 1963 and 1964, Murray Gell-Mann, André Peterman and George Zweig independently developed the concept of quarks ...
