Astronomers observe subpulse drifting and nulling of pulsar PSR J0026–1955
Using the upgraded Giant Meterwave Radio Telescope (uGMRT), astronomers from India and Australia have performed radio observations of a pulsar known as PSR J0026–1955. Results of the observational campaign, published July 5 on the preprint server a.....»»
Observations explore the properties of giant spiral galaxy UGC 2885
Astronomers have employed the Canada-France-Hawaii Telescope (CFHT) to perform comprehensive multiwavelength observations of a large and massive spiral galaxy known as UGC 2885. Results of the observational campaign, published October 21 on the pre-p.....»»
Astronomers take a close look at a dandelion-shaped supernova and zombie star
In 1181, a new star shone near the Cassiopeia constellation for six months before disappearing. This event, recorded as a "guest star" by Chinese and Japanese observers almost a millennium ago, has puzzled astronomers for centuries. It is one of a fe.....»»
Astronomers discover a bright pulse that may be a fast radio burst
Searching for pulsars using the Large Phased Array (LPA) radio telescope, Russian astronomers have detected a bright pulse at a frequency of 111 MHz, which appears to be a fast radio burst event. The finding was reported in a research paper published.....»»
Observations explore the nature of stellar stream Icarus
Astronomers from Italy and Chile have investigated an accreted stellar stream named Icarus in the Milky Way's disk. Results of the study, detailed in a research paper published October 16 on the preprint server arXiv, yield crucial information regard.....»»
Astronomers explore the properties of an obscured hyperluminous quasar
Astronomers from the European University Cyprus and the University of Hawaii have investigated a recently discovered obscured hyperluminous quasar known as COS-87259. Results of the study, published October 14 in the Monthly Notices of the Royal Astr.....»»

A look into cloudy liquids: New method makes the expansion of turbid drops in water visible
When driving though a bank of fog, car headlights are only of limited help as the light is scattered by the water particles suspended in the air. The situation is similar when you try to observe the inside of a drop of milk in water or the internal s.....»»
Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
Second exoplanet detected orbiting an early G-type star
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding was detailed in a research p.....»»
Astronomers detect very-high-energy gamma-ray emission surrounding distant pulsar
Using the Large High-Altitude Air Shower Observatory (LHAASO), an international team of astronomers have detected very-high-energy (VHE) gamma-rays around the pulsar PSR J0248+6021, which may be the pulsar's halo or a pulsar wind nebula. The finding.....»»
Saturn Trojan asteroid confirmed
A small international team of astronomers and astrophysicists has confirmed that asteroid 2019 UO14 is a Trojan asteroid of Saturn. The team has posted a paper describing their study of the asteroid on the arXiv preprint server......»»
Astronomers observe a strong superflare from giant star
Using the Neutron Star Interior Composition Explorer (NICER) and various ground-based telescopes, an international team of astronomers have performed observations of a strong X-ray superflare which occurred in 2022 on a giant star known as HD 251108......»»
Saturday Citations: All that sparkles is plastic; woke tree diversity; the gravitational basin in which we reside
This week, astronomers considered whether dark energy varies over cosmic timescales. Via neutron analysis, physicists revealed that some Early Iron Age swords were altered recently by swindlers in order to be more historically exciting. And a profess.....»»
"Inside-out" galaxy growth observed in the early universe
Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the 'inside-out' growth of a galaxy in the early universe, only 700 million years after the Big Bang......»»
Asteroid mining: A potential trillion-dollar industry
Earth's newest celestial neighbor has finally arrived. Astronomers using a powerful telescope in Sutherland, South Africa, first detected the 33-foot-long asteroid in August, reporting their discovery in Research Notes of the American Astronomical So.....»»
Astronomers find Webb data conflict with reionization models
Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this epoch ended around 1 billion years after the Big Bang......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
Team discovers three new magnetic and helium-enriched hot subdwarf stars
An international team of astronomers reports the discovery of three new helium-enriched hot subdwarf stars with strong magnetic fields. The finding, made with the Southern African Large Telescope (SALT), is detailed in a research paper published Oct......»»
