由荷兰、英国、法国、德国等多个国家共同建设的泛欧射频望远镜阵列（LOFAR）将进行一次系统升级。
Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge.
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions. Previous ...

在对北半球微波范围内的天空进行观测近十年后，QUIJOTE合作团队在《皇家天文学会月刊》（MNRAS）上发表文章，对银河系微波辐射过程中在10—20GHz波长光的极化进行了最准确的描述，补充了以前在微波下观测天空的空间任务（欧空局的Planck和美国宇航局的WMAP）。这是一个以前没有探索过的观测窗口，致力于研究宇宙微波背景辐射（CMB）。新的结果使科学家能够获得关于银河系磁场结构的信息，并有助于...
Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of ancient life on the red planet may not be sensitive enough to make accurate assessments, according to an ...

英国埃克塞特大学科研人员领导的一个国际科学家小组发现了一颗新的围绕恒星HD206893运行的系外行星，距离地球约750万亿英里，体积比太阳大30％。
The ongoing search for signs of life on Mars relies in part on terrestrial analogs – places on Earth closely resembling the past or current geology and climate of the red planet that can be readily ex...
The eerie sound of an extraterrestrial whirlwind has reached the Earth from more than 50 million miles away, thanks to the first working microphone to traverse the surface of Mars. The audio records t...
Arecent Nature publication continues to generate headlines over its findings that scientists from the California Institute of Technology developed a model of a traversable wormhole on the Google Sycam...
The antimatter counterpart of a light atomic nucleus can travel a long distance in the Milky Way without being absorbed, shows the international ALICE collaboration in an article published today in Na...
Study: Without more data, a black hole’s origins can be “spun” in any direction（图）
