Quasi-periodic oscillations detected in pulsar LMC X-4
Using ESA's XMM-Newton telescope, Indian astronomers have performed X-ray observations of a binary X-ray pulsar known as LMC X-4. The observational campaign resulted in the detection of quasi-periodic oscillations (QPOs) in this source. The finding i.....»»
European Southern Observatory telescopes help unravel pulsar puzzle
With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning d.....»»
A particular way of creating quantum entanglement may improve accuracy of advanced quantum sensors
Metrological institutions around the world administer our time using atomic clocks based on the natural oscillations of atoms. These clocks, pivotal for applications like satellite navigation or data transfer, have recently been improved by using eve.....»»
India"s moon rover confirms sulfur and detects several other elements near the lunar south pole

A new route for universal polarization transformations of spatially varying polarization fields
Polarization describes the orientation of oscillations in a light wave, and it plays an essential role in various optical applications—from enhancing visibility in sunglasses and camera lenses to facilitating advanced optical communication and imag.....»»
New supernova remnant detected with ASKAP
Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has serendipitously detected a new Galactic supernova remnant (SNR), which received designation SNR G288.8–6.3. The finding was reported in a paper.....»»
Ransomware dwell time hits new low
Median attacker dwell time—the time from when an attack starts to when it’s detected—shrunk from 10 to eight days for all attacks, and to five days for ransomware attacks during the first half of 2023, according to Sophos. In 2022, the median d.....»»
Astronomers discover eight ultraluminous X-ray sources in NGC 1559
Astronomers from Taiwan have performed X-ray observations of the galaxy NGC 1559 using NASA's Chandra spacecraft. They detected eight new ultraluminous X-ray sources in this galaxy. The finding is reported in a paper published August 10 on the pre-pr.....»»
Emergency detected in pre-moon landing maneuver by Russia"s Luna-25 probe
An "emergency" was detected on Saturday during a maneuver by Russia's Luna-25 probe prior to its Moon landing, Russian space agency Roscosmos said......»»
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.....»»
Phishers use QR codes to target companies in various industries
A phishing campaign using QR codes has been detected targeting various industries, with the aim to acquire Microsoft credentials. “The most notable target, a major Energy company based in the US, saw about 29% of the over 1000 emails containing.....»»
Astronomers confirm Maisie"s galaxy is among earliest ever observed
Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are published in the j.....»»
New massive brown dwarf discovered
Astronomers report the discovery of a new massive brown dwarf using the Zwicky Transient Facility (ZTF). The newly detected object is about 80 times more massive than Jupiter and orbits a low-mass star. The finding was detailed in a paper published J.....»»
Avian botulism detected at California"s resurgent Tulare Lake, raising concern for migrating birds
Wildlife authorities have detected avian botulism at California's resurgent Tulare Lake, raising concerns about potential die-offs during fall bird migrations......»»
Webb telescope reveals colors of Earendel, most distant star ever detected
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star.....»»
After 15 years, pulsar timing yields evidence of cosmic background gravitational waves
The universe is humming with gravitational radiation—a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it......»»
Stealth swimmers: The fish that hide behind other fish to hunt
A new study provides the first experimental evidence that the trumpetfish, Aulostomus maculatus, can conceal itself by swimming closely behind another fish while hunting—and reduce the likelihood of being detected by its prey. The study, involving.....»»
NASA helps spot wine grape disease from skies above California
In a case study, scientists detected the costly infection in cabernet sauvignon grapevines before they showed symptoms visible to the human eye......»»
