Satellites Keep Photobombing Space Images. Astronomers Need a Fix
A new technique could aid Hubble Space Telescope users, but the problem will get worse for observatories on Earth......»»
Team lays groundwork for future ultra-precise timing links to geosynchronous satellites
Last year, scientists drove up Mauna Loa volcano on Hawai'i, aimed a laser at a reflector positioned on Haleakala peak on Maui, and beamed rapid pulses of laser light through 150 kilometers of turbulent air. While the pulses were exceedingly faint, t.....»»
CERN plans to collaborate with projects for future gravitational-wave observatories
Gravitational waves, like the discovery of the Higgs boson in 2012, have made their mark on a decade of extraordinary discoveries in physics. Unlike gravity, which is created when massive objects leave their mark in the fabric of spacetime, gravitati.....»»
Six Gravitational-Wave Breakthroughs Scientists Can"t Wait to See
After years of downtime for upgrades, the world’s premier gravitational-wave observatories are coming back online with big hopes for transformative discoveries.....»»
New measurements suggest rethinking the shape of the Milky Way galaxy
A team of space scientists with the Chinese Academy of Sciences, at both the Purple Mountain Observatory and the National Astronomical Observatories, has found that the traditional view of the Milky Way galaxy as having four arms is not correct. In t.....»»
Ground wide angle camera array detects prompt optical emission of gamma-ray burst
Researchers led by Dr. Xin Liping from the Space-based Multi-band Astronomical Variable Objects Monitor (SVOM) research team, National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), have detected the prompt optical emission and.....»»

Scientists discover pre-low-mass white dwarf binary using LAMOST
A binary system containing an extremely low-mass (ELM) white dwarf (WD) progenitor and a compact invisible companion, was discovered by Chinese astronomers from the National Astronomical Observatories of Chinese Academy of Sciences (NAOC), using spec.....»»
Plans are underway to build a 30-cubic-kilometer neutrino telescope
How do astronomers look for neutrinos? These small, massless particles whiz through the universe at very close to the speed of light. They've been studied since the 1950s and detecting them provides work for a range of very interesting observatories......»»
Radio interference from satellites is threatening astronomy
A proposed zone for testing new technologies could head off the problem. Enlarge / Radio observatories like the Green Bank Telescope in Green Bank, West Virginia, are in radio quiet zones that protect them from interference. (cr.....»»
Radio interference from satellites is threatening astronomy—zone proposed for testing new technologies
Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other space telescopes capture X-ray images, and observatories like the Green B.....»»
Researchers observe solar filament formation caused by oscillation magnetic reconnection
Researchers led by Yan Xiaoli from the Yunnan Observatories of the Chinese Academy of Sciences, in collaboration with Sun Xia and Liang Hongfei from Yunnan Normal University, have clearly observed the formation of an intermediate solar filament cause.....»»
Theoretical support for reality of pressure mode pulsations on a white dwarf
Researchers from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) have conducted a detailed asteroseismic analysis on an extremely low-mass white dwarf (WD) that exhibits suspected pressure mode (p-mode) pulsations. They not only det.....»»
Scientists discover new form of oscillations in single filament driven by two-sided-loop jet
Researchers led by Prof. Shen Yuandeng and his student Tan Song from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) have discovered new form of oscillation in a single filament driven by a two-sided-loop jet......»»
Precise FAST observations reveal circular polarization in active repeating fast radio bursts
A research team led by Prof. Li Di from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has revealed circular polarization in active repeating fast radio bursts based on precise observations of the Five-hundred-meter.....»»
Hydrodynamical simulations for the common-envelope wind model for Type Ia supernovae
Ph.D. candidate Cui Yingzhen and Prof. Meng Xiangcun from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) performed hydrodynamic simulations on the common-envelope wind model of Type Ia supernovae (SNe Ia), and revealed the mass los.....»»
Three quarters of major observatories affected by light pollution
Researchers from Italy, Chile and Galicia have studied and compared the light pollution levels at major astronomical observatories across the world. The study shows that light is polluting the sky above most observatories and that immediate action is.....»»
Mauna Loa lava no longer imminent threat to Hawaii highway
Lava from the world's largest volcano is no longer an imminent threat to the main highway across the Big Island of Hawaii, scientists said Thursday, a development that was a welcome reprieve for motorists who depend on the road......»»
Hawaii road in limbo as Mauna Loa lava continues to crawl
About a week-and-a-half since the world's largest volcano began erupting, Hawaii officials continue to brace for slow-moving lava to intersect with a crucial Big Island road, even though scientists are not sure when or even if that will happen......»»
