Not long ago, the idea of photographing a black hole was as quixotic as photographing a unicorn. Now, scientists have not one but two images of two different supermassive black holes — and they both l...
An international team of more than 300 scientists from 80 institutions has created the first-ever image of the supermassive black hole at the center of our Milky Way galaxy.

The flashing of a nearby star has drawn MIT astronomers to a new and mysterious system 3,000 light years from Earth. The stellar oddity appears to be a new “black widow binary” — a rapidly spinning ne...
Scattered across our Milky Way galaxy are tens of millions of black holes — immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black hole...
Over the next 10 years, a collection of the nation’s top planetary scientists and astrobiologists – using suggestions from panels chaired by two Cornell professors – are advocating for exploratory voy...
日冕物质抛射(CME)是灾害性空间天气的主要驱动源，如何针对特定的CME事件, 了解其在日冕和行星际空间的传播特性及演化过程，预测近地空间太阳风状态的变化，是空间天气研究领域的重要内容，同时受到国内外学者的广泛关注，近年来，在CME传播特性的观测和数值模拟研究中取得了大量进展。
