Two months ago, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) notified astronomers around the world of the possible detection of gravitational waves from the merger of two ne...
For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space -- the birt...
When a pair of superdense neutron stars collided and potentially formed a black hole in a galaxy 130 million light-years from Earth, they unleashed not only a train of gravitational waves but also an ...
Journalists are invited to join the National Science Foundation (NSF) as it brings together scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo collaborations, as ...
A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of exoplanets -- planets beyond our solar system. With the new attachment, ground-based t...
In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by thr...
For the first time, three detectors have tracked the gravitational waves emitted by a merger of two black holes -- a critical new capability that allows scientists to more closely locate a gravitation...
美国斯坦福大学与SLAC国家实验室的研究人员近日宣布,利用神经网络的人工智能算法分析被称为“引力透镜”的复杂时空扭曲现象,可在不到1秒的时间内完成,比传统方法快了1000万倍以上。这一成果发表在最新一期出版的《自然》杂志上。引力透镜指大质量天体(如星系团)的引力改变了更远天体的光路,使之被望远镜观测时发生扭曲的现象。引力透镜提供了质量在宇宙空间中分布的线索,是研究暗物质与暗能量的重要途径。传统上,...
Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high-energy cosmic rays—whet...
In an article to be published Sept. 22 in the journal Science, a group of more than 400 scientists from 18 nations describe how they detected an anisotropy, an asymmetry in the cosmic particles’ distr...
A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White...
Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof tha...
Scientists have never directly detected dark matter. But over decades, they have proposed a variety of theories about what type of material — from new particles to primordial black holes — could compr...
In a briefing today on solar eclipse science, leading U.S. scientists highlighted research projects that will take place across the country during the upcoming August 21 solar eclipse. The research wi...
The total solar eclipse next month is the first to cross the U.S. from coast to coast in nearly a century, giving scientists a unique opportunity to observe the sun's corona with an array of technolog...
