Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
Biosensors mimic human olfactory system to discriminate between very similar odors
The human olfactory system discriminates between thousands of odors by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different intensities, and the same odorant can activate more th.....»»
Latest gravitational wave observations conflict with expectations from stellar models
Almost 300 binary mergers have been detected so far, indicated by their passing gravitational waves. These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging objects such as black hol.....»»
Miniature sensor that detects toxic gas shows promising results in the lab
A team of scientists at UNSW Sydney have developed a highly sensitive miniature sensor that is able to detect low levels of the toxic gas nitrogen dioxide (NO2). The tiny, flexible sensor can detect the harmful gas in real-time without requiring an e.....»»

Unveiling the uncharted Milky Way: Completing the galactic stellar map
By peering into the cosmic dance of stars, a team led by researchers from the Leibniz Institute for Astrophysics Potsdam (AIP) has unraveled the complex structure of our Milky Way galaxy. Assuming that each observed star represents a larger populatio.....»»
Astronomers detect new 1.9-second pulsar using FAST
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers have discovered a new pulsar with a spin period of about two seconds. The newly detected pulsar, designated PSR J1922+37, was found in the direction of open.....»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Where"s my qubit? Scientists develop technique to detect atom loss
Quiet quitting isn't just for burned out employees. Atoms carrying information inside quantum computers, known as qubits, sometimes vanish silently from their posts. This problematic phenomenon, called atom loss, corrupts data and spoils calculations.....»»
Survey of 26,000 dead stars confirms key details of extreme stellar behavior
A study of more than 26,000 white dwarf stars has confirmed a long-predicted but elusive effect in these ultra-dense, dying stars: Hotter white dwarfs are slightly puffier than cooler ones, even when they have the same mass......»»
Hyperspectral imaging lidar system achieves remote plastic identification
Researchers have developed a new hyperspectral Raman imaging lidar system that can remotely detect and identify various types of plastics. This technology could help address the critical issue of plastic pollution in the ocean by providing better too.....»»
NASA missions spot cosmic "wreath" displaying stellar circle of life
Since antiquity, wreaths have symbolized the cycle of life, death, and rebirth. It is fitting then that one of the best places for astronomers to learn more about the stellar lifecycle resembles a giant holiday wreath itself......»»
ALMA observations investigate disk and jet of a massive protostar
Astronomers from Italy and Spain have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a massive protostar designated IRAS 20126+4104. The observational campaign, detailed in a paper published Dec. 9 on the arXiv preprint serve.....»»
Waal river draws more water, signaling potential Rhine system shift
Historical observations and model computations point to the Rhine system having crossed a tipping point. Since extreme peak flows in the 1990s, the Waal has gradually attracted more water at the Pannerdense Kop bifurcation. This is shown in research.....»»

What is a dark comet? A quick guide to the "new" kids in the solar system
In 2017, NASA discovered and later confirmed the first interstellar object to enter our solar system......»»
Airborne observations identify major source of US landfill methane emissions
A team has found via testing from airplanes that landfill work faces tend to be responsible for the biggest share of methane emissions in U.S. landfills. Their findings are published in the journal Environmental Science and Technology. The researcher.....»»
M87"s powerful jet unleashes rare gamma-ray outburst
Also known as Virgo A or NGC 4486, M87 is the brightest object in the Virgo cluster of galaxies, the largest gravitationally bound type of structure in the universe. It came to fame in April 2019 after scientists from EHT released the first image of.....»»
Observations suggest sun-like stars emit superflares once per century
There is no question that the sun is a temperamental star, as this year's unusually strong solar storms show. Some of them led to remarkable auroras even at low latitudes. But can our star become even more furious?.....»»
Nanopatterned graphene enables infrared "color" detection and imaging
University of Central Florida (UCF) researcher Debashis Chanda, a professor at UCF's NanoScience Technology Center, has developed a new technique to detect long wave infrared (LWIR) photons of different wavelengths or "colors.".....»»
