Two millisecond pulsars detected in globular cluster NGC 6440
Using the MeerKAT radio telescope, an international team of astronomers has investigated a globular cluster known as NGC 6440. In result, two new millisecond pulsars have been detected in this cluster, which received designations NGC 6440G and NGC 64.....»»
Does this exoplanet have a "sibling" sharing the same orbit?
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found the possible "sibling" of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit, which they believe co.....»»
Researchers operating Gamma-ray Burst Monitor discover brightest gamma-ray burst ever detected
The University of Alabama in Huntsville (UAH) has announced that three researchers associated with the UAH Center for Space Plasma and Aeronomic Research (CSPAR) have discovered a gamma-ray burst (GRB) approximately 2.4 billion light-years away in th.....»»
New tidal disruption event discovered by Chinese astronomers
Astronomers from the University of Science and Technology of China in Hefei report the discovery of a new faint tidal disruption event (TDE). The newfound TDE, designated AT 2023clx is the faintest and closest optical TDE so far detected. The finding.....»»
Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
Image: Hubble views a galactic monster
The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collect.....»»
We"ve detected a star barely hotter than a pizza oven—the coldest ever found to emit radio waves
We have identified the coldest star ever found to produce radio waves—a brown dwarf too small to be a regular star and too massive to be a planet......»»

Microsoft takes pains to obscure role in 0-days that caused email breach
Critics also decry Microsoft's "pay-to-play" monitoring that detected intrusions. Enlarge (credit: Getty Images | Aurich Lawson) On Friday, Microsoft attempted to explain the cause of a breach that gave hackers working f.....»»
Astronomers discover a luminous nuclear transient
Using NASA's Swift spacecraft, an international team of astronomers has discovered a luminous and slowly-evolving nuclear transient event. The origin of the newly detected transient, designated Swift J221951-484240, is yet to be determined. The findi.....»»
Millisecond coherence reached for fluxonium qubit
A team of physicists at the University of Michigan's Joint Quantum Institute and Center for Nanophysics and Advanced Materials has achieved millisecond coherence while testing the properties of a fluxonium qubit in a quantum circuit. In their study,.....»»
Astronomers use dead stars to measure gravitational waves produced by ancient black holes
An international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration—called NANOGrav—was able to meas.....»»
Astronomers puzzled by "planet that shouldn"t exist"
The search for planets outside our solar system—exoplanets—is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at l.....»»
In a First, Scientists See Neutrinos Emitted by the Milky Way
The disk of our galaxy was long thought to produce these ghostly high-energy particles, but they haven’t been detected until now.....»»
First "ghost particle" image of Milky Way galaxy captured by scientists: Neutrinos detected by IceCube
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a horizon-to-horizon hazy band of stars. Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrino.....»»
At Last, There’s Evidence of Low-Frequency Gravitational Waves
A globe-spanning group of physicists used pulsars to measure the waves, which they believe emanated from pairs of supermassive black holes......»»
Clock-like precision of pulsars opens new window for studying gravitational waves
A team of European astronomers, along with Indian and Japanese colleagues, has reported evidence that strongly suggests the detection of ultra-low-frequency gravitational waves. Such waves, which have not previously been observed, probably originate.....»»
The Universe Is Abuzz with Giant Gravitational Waves, and Scientists Just Heard Them (Maybe)
Researchers, using the galaxy as a detector, believe they have detected gravitational waves from monster black holes for the first time......»»
NANOGrav hears “hum” of gravitational wave background, louder than expected
Exotic stars called millisecond pulsars serve as celestial metronomes. Enlarge / In this artist’s interpretation, a pair of supermassive black holes (top left) emits gravitational waves that ripple through the fabric of space-t.....»»
