Peculiar nova eruption inspected by astronomers
An international team of astronomers has employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe the eruption of Nova Vulpeculae 2021. Results of the observational campaign, published November 8 on the pre-print server arXiv, provide.....»»
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.....»»
Scientists update eruption history of Oregon"s South Sister volcano
A hiker's pack usually gets lighter over time as they plow through trail mix and water, but Annika Dechert likes to joke that hers gets heavier. As an Earth sciences graduate student at the University of Oregon, she's picking up clues to the eruption.....»»
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.....»»
Fungi finding: mushroom hunters seek new species and recognition
You can't walk very far through a forest in this part of the United States without stumbling upon a mushroom, an eruption from a vast fungal kingdom that all life depends on, but about which we know very little......»»

Rare ultra-luminous nova spotted in the Small Magellanic Cloud
A rare, extremely luminous X-ray outburst has been observed in the Small Magellanic Cloud, a dwarf galaxy that is a close neighbor of our own Milky Way galaxy. The observations, made by the Neil Gehrels Swift Observatory and other telescopes, were de.....»»
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.....»»
Report: Climate emergencies threaten our collective security, but governments are flying blind into the storm
You probably missed it, but a few months ago a report was published that inspected how the UK government prepared for major emergencies. What it found has profound implications for the whole country......»»
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......»»
Anti-glitches detected in gamma-ray pulsar PSR J1522-5735
By analyzing the data from NASA's Fermi Gamma-ray Space Telescope, Russian astronomers have detected anti-glitches in a gamma-ray pulsar designated PSR J1522-5735. The discovery, published September 28 on the pre-print server arXiv, makes PSR J1522-5.....»»
