13-11-25 Astrophysicists using a telescope embedded in Antarctic ice have succeeded in a quest to detect and record the mysterious phenomena known as cosmic neutrinos -- nearly massless particles that stream to Earth at the speed of light from outside our so...

13-09-02 The origin of cosmic rays in the universe has confounded scientists for decades. But a study by researchers using data from the IceCube Neutrino Observatory at the South Pole reveals new information that may help unravel the longstanding mystery of...

13-03-21 Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere（太阳风层） , according to a new study appearing online today. The heliosphere is a region of space dominated by the S...

12-05-24 The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations（扰动，不安） of matter that grew over time, like ripples in a pon...

12-04-19 Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is homing in on how the highest energy cosmic rays are p...

11-10-03 The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological（宇宙论的） simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic mysteries as galaxy formation, dark matter...

10-11-23 Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of（缺乏） stars. Cosmic dust is the indispensable（不可缺少的） ingredient for making stars and for understanding how primor...

10-07-22 Pioneering（首创的，先驱的） observations with the National Science Foundation's giant Robert C. Byrd Green Bank Telescope (GBT) have given astronomers a new tool for mapping large cosmic structures. The new tool promises to provide valuable clues a...

10-03-28 University of British Columbia astronomer Ludovic Van Waerbeke with an international team has confirmed that the expansion of the universe is accelerating after looking at data from the largest-ever survey conducted by the Hubble Space Telescope. Th...

09-10-29 Astronomers have confirmed that an exploding star spotted by Nasa's Swift satellite is the most distant cosmic object to be detected by telescopes. 天文学家已经证实，美国航空航天局的威夫特卫星拍摄到的一颗爆发星是天文望远镜探测到的最远的宇宙星体。 Th...
