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.
Astronomers snap first-ever image of supermassive black hole Sagittarius A*（图）
超大质量黑洞 人马座A* 银河系

An enormous hole 22 meters in diameter has been dug near the summit of Cerro Chajnantor in Chile’s Atacama Desert, at an elevation of 18,400 feet. The hole stands ready for the cement foundation on wh...
Astronomers discover a rare “black widow” binary, with the shortest orbit yet（图）
“黑寡妇”双星 恒星 伴星环 银河系
2023/6/9
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。
The most distant galaxy on record has been spotted by an international team of astronomers, including researchers at the Center for Astrophysics | Harvard & Smithsonian.
At the Quark Matter conference today and at the recent Rencontres de Moriond conference, the LHCb collaboration presented an analysis of particle collisions at the Large Hadron Collider (LHC) that may...
Scientists develop the largest, most detailed model of the early universe to date（图）

It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically...
It looks like fireflies flickering in the darkness. Slowly, more and more amass, lighting up the screen in large chunks and clusters.
On the evening of Dec. 12, 2021, Cornell astronomers Gordon Stacey and Thomas Nikola were dangerously short on time. They’d been awake for nearly 24 hours, with another all-nighter ahead of them.
Aided by microbes found in the subarctic conditions of Canada’s Hudson Bay, an international team – including researchers from Portugal’s Instituto Superior de Agronomia and Técnico, Canada’s Universi...
Yen-Jie Lee probes particle collision data for clues to the universe’s origins（图）
