Two intermediate polars investigated by astronomers
By analyzing the long-term, high-cadence continuous photometry from NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have investigated UU Columbae and Swift J0939.7-3224—two intermediate polars. Results of the study, presented July.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
Bach, Mozart or jazz: Scientists provide a quantitative measure of variability in music pieces
Physicists at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have investigated to which extent a piece of music can evoke expectations about its progression. They were able to determine differences in how far compositions of dif.....»»
Globular cluster Gran 5 hosts two stellar populations, study finds
Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations with different metallicities.....»»
Researchers uncover focal adhesions as subcellular signaling hubs in PI3K-AKT pathway
The phosphatidylinositol 3-kinase (PI3K)-AKT signaling pathway is one of the most critical and extensively investigated signaling pathways. It is the central regulator of various cellular processes including cell growth, proliferation, metabolism, an.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
Learning more about supernovae through stardust
Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something astronomers strive to und.....»»
New insights into mango evolution: Study reveals extensive hybridization within the Mangifera genus
A research team investigated whole chloroplast genomes and nuclear gene sequences from 14 species, uncovering new insights into the genetic diversity and hybrid origins of mango species. They used the evolutionary relationships within the Mangifera g.....»»
Astronomers predict the orbits of potentially hazardous comets from meteor showers
Comets have long been seen as omens and portents, and it's easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They h.....»»
Astronomers investigate the properties of open cluster NGC 2506
Astronomers from the University of Wisconsin–Madison and Harvard–Smithsonian Center for Astrophysics (CfA) have inspected a Galactic open cluster known as NGC 2506 as part of the WIYN Open Cluster Study. Results of the study, published October 14.....»»
Machine-learning analysis tracks the evolution of 16th-century European astronomical thought
A team of computer scientists, astronomers and historians in Berlin has used machine-learning applications to learn more about the evolutionary history of European astronomical thought in the 15th and 16th centuries. In their study published in the j.....»»
Researchers show nanoplastics can reduce the effectiveness of antibiotics
In a recent study, an international research team with significant involvement from MedUni Vienna has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics......»»
New extended and faint tidal tail discovered
By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers have discovered a new tidal tail likely associated with the galaxy NGC 3785. The newly detected tidal tail is extremely extended and faint. The finding was reported.....»»
Innovative model offers new way for astronomers to analyze powerful space explosions
Astrophysical explosions are, to give a few examples, driven by the collapse of the iron core of a massive star (known as a core-collapse supernova), the consumption of spaghettified stellar remains by a massive black hole (known as a tidal disruptio.....»»
Using multimode propulsion for more efficient trips in space
Over the span of two projects, researchers at the University of Illinois Urbana-Champaign investigated using a propulsion concept known as multimode propulsion to get spacecraft to the moon and developed a technique to design optimal multimode transf.....»»
Astronomers discover one of the fastest-spinning stars in the universe
A new study by DTU Space researchers has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever observed......»»
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.....»»
