Can you spot it
Feb 13, 2023 (ESA)
Donatiello II is one of three newly discovered galaxies that were so difficult to spot that they were all missed by an algorithm designed to search astronomical...
HETDEX reveals galaxy gold mine in first large survey
Feb 10, 2023 (SPX)
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) has scanned the dark skies of the Davis Mountains in West Texas since 2017 with a keen eye towards ca...
Toward practical quantum optics: multiphoton qubits from LNOI
Feb 09, 2023 (SPX)
Among all quantum systems, photons are known for their weak interaction, which allows long coherence time to be achieved even at room temperature, making them s...
China's gigantic telescope identifies over 740 pulsars
Feb 09, 2023 (XNA)
Pulsars, or fast-spinning neutron stars, originate from the imploded cores of massive dying stars through supernova explosions. Pulsar observation is an importa...
Footprints of galactic immigration uncovered in Andromeda galaxy
Feb 09, 2023 (SPX)
An international team of researchers has uncovered striking new evidence of a large galactic immigration event in the Andromeda Galaxy, the Milky Way's nearest ...
Researchers find distortion-free forms of structured light
Feb 09, 2023 (SPX)
Each pattern could form an encoding alphabet for optical communication or might be used in manufacturing to enhance performance and productivity. Unfortunately,...
Distortion-free structured light
Feb 08, 2023 (SPX)
In all these examples, the distorted pattern can deteriorate to the point that the output pattern looks nothing like the input, negating the benefit. As reporte...
In search of the invisible galaxy
Feb 08, 2023 (SPX)
An extremely remote celestial body in a still young Universe, one sixth the size of the present one. An object so dark that it is almost invisible, even to high...
Study reveals complex chemistry inside 'stellar nurseries'
Feb 07, 2023 (SPX)
Like human bodies, stellar nurseries contain a lot of organic molecules, which are made up mostly of carbon and hydrogen atoms. The group's results, published F...
Distant galaxy mirrors the early Milky Way
Feb 07, 2023 (SPX)
The discovery of The Sparkler was made using some of the first data from the James Webb Space Telescope. The Sparkler, named for its two dozen orbiting globular...
Upconversion of infrared photons enables rapid organic synthesis under sunlight
Feb 07, 2023 (SPX)
The study was published in Nature Photonics on Feb. 6. Upconversion of near-infrared photons to visible photons can boost the performance of photovoltaics, phot...
Researchers devise a new path toward 'quantum light'
Feb 03, 2023 (SPX)
The researchers, from the University of Cambridge, along with colleagues from the US, Israel and Austria, developed a theory describing a new state of light, wh...
For the First Time Hubble Directly Measures Mass of a Lone White Dwarf
Feb 03, 2023 (SPX)
Researchers found that the white dwarf is 56 percent the mass of our Sun. This agrees with earlier theoretical predictions of the white dwarf's mass and corrobo...
A spiral amongst thousands
Feb 01, 2023 (ESA)
The large spiral galaxy at the base of this image is accompanied by a profusion of smaller, more distant galaxies which range from fully-fledged spirals to mere...
Untangling a knot of galaxy clusters
Jan 31, 2023 (SPX)
The giant galaxy cluster forming from this collision is Abell 2256, located 780 million light years from Earth. This composite image of Abell 2256 combines X-ra...
Waseda researchers measure boron flux in high-energy cosmic rays with CALET
Jan 27, 2023 (SPX)
Existing studies indicate that ^ follows a power-law variation. It is inversely related to E raised to the dth power, where E is the CR energy per nucleon and d...
Solar System formed from 'poorly mixed cake batter'
Jan 27, 2023 (SPX)
"The extreme conditions found in stellar interiors enable stars to manufacture elements using nuclear fusion," explained Nie, a former Carnegie postdoc now at C...
NASA's Fermi detects first gamma-ray eclipses from 'Spider' Systems
Jan 27, 2023 (SPX)
An international team of scientists scoured over a decade of Fermi observations to find seven spiders that undergo these eclipses, which occur when the low-mass...
Starry tail tells the tale of dwarf galaxy evolution
Jan 27, 2023 (SPX)
Astronomers using the Subaru Telescope and the Canada-France-Hawaii Telescope found a tail of stars stretching 200,000 light-years out away from a galaxy known ...
Were galaxies much different in the early universe?
Jan 25, 2023 (SPX)
In a paper accepted for publication in The Astrophysical Journal, the Hydrogen Epoch of Reionization Array (HERA) team reports that it has doubled the sensitivi...
