Daily Telescope: The Milky Way above one of my favorite places on Earth
This photo is really not that much different than what you'll see with the naked eye. Enlarge / The Milky Way above Mauna Kea. (credit: Samuel Muller) Welcome to the Daily Telescope. There is a little too much darknes.....»»
How a small town in Japan fiercely defends its dark skies
Light pollution ruins dark skies. It's a scourge that ground-based observatories have to deal with in one form or another. Scientists used a small observatory in Japan to measure what changed when a nearby town improved its lighting practices. They a.....»»
Constraining the dynamics of rotating black holes via the gauge symmetry principle
In 2015, the LIGO/Virgo experiment, a large-scale research effort based at two observatories in the United States, led to the first direct observation of gravitational waves. This important milestone has since prompted physicists worldwide to devise.....»»
Scientists are recommending IceCube should be eight times bigger
The IceCube Neutrino Observatory, operated by the University of Wisconsin-Madison (UW-M), located at the Amundsen–Scott South Pole Station in Antarctica, is one of the most ambitious neutrino observatories in the world. Behind this observatory is t.....»»
A volcano on Hawaii"s Big Island is sacred to spiritual practitioners and treasured by astronomers
Shane Palacat-Nelsen's voice drops to a reverent tone as he tells the story of the snow goddess Poliahu who Native Hawaiians believe inhabits the summit of Mauna Kea, the highest point in Hawaii......»»
PUNCH mission advances toward 2025 launch
On November 17, 2023, the Polarimeter to UNify the Corona and Heliosphere (PUNCH) mission achieved an important milestone, passing its internal system integration review and clearing the mission to start integrating its four observatories. Southwest.....»»
Researchers obtain evidence for nanoflares heating coronal loops

Cataclysmic variable Swift J0503.7-2819 investigated by researchers
Using various spacecraft and ground-based observatories, an international team of astronomers has performed a multi-wavelength study of a cataclysmic variable system known as Swift J0503.7-2819. Results of the study, published October 11 on the pre-p.....»»
Investigating the evolution of a double oxygen-neon white dwarf merger remnant
A research group led by assistant professor Wu Chengyuan from Yunnan Observatories of the Chinese Academy of Sciences has investigated the evolution of post-merger remnant resulting from the coalescence of double oxygen-neon white dwarfs. They have f.....»»
NASA team simulates a glimpse of our galaxy in gravitational waves
Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wave observatories expected to la.....»»
It"s time for a gravitational wave observatory in the Southern Hemisphere, say researchers
What's true for optical astronomy is also true for gravitational wave astronomy: The more observatories you have, the better your view of the sky. This is why the list of active gravitational wave observatories is growing. But so far they are all in.....»»
Researchers propose using pulsars to localize gravitational wave sources
Current gravitational wave observatories have two significant limitations. The first is that they can only observe powerful gravitational bursts such as the mergers of black holes and neutron stars. The second is that they can only observe these merg.....»»
Scientists use FAST to discover a new population of "dwarf" pulses
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. Han Jinlin from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has detected distinct "dwarf pulses" from a bright.....»»
Using cosmic weather to study which worlds could support life
As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away exoplanets......»»
World"s largest filled-aperture radio telescope finds missing link in evolution of spider pulsar system
