Two millisecond pulsars detected in globular cluster NGC 6440
Using the MeerKAT radio telescope, an international team of astronomers has investigated a globular cluster known as NGC 6440. In result, two new millisecond pulsars have been detected in this cluster, which received designations NGC 6440G and NGC 64.....»»
Astronomers confirm Maisie"s galaxy is among earliest ever observed
Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are published in the j.....»»
New massive brown dwarf discovered
Astronomers report the discovery of a new massive brown dwarf using the Zwicky Transient Facility (ZTF). The newly detected object is about 80 times more massive than Jupiter and orbits a low-mass star. The finding was detailed in a paper published J.....»»
Avian botulism detected at California"s resurgent Tulare Lake, raising concern for migrating birds
Wildlife authorities have detected avian botulism at California's resurgent Tulare Lake, raising concerns about potential die-offs during fall bird migrations......»»
Novel mechanism for oxygen evolution reaction on dual-atom catalysts increases reaction activity
Atomically precise cluster catalysts bridge the gap between homogeneous and heterogeneous catalysis, facilitating comprehensive elucidation of structure-activity relationships in catalytic processes. However, the synergistic effects between non-singl.....»»
Webb telescope reveals colors of Earendel, most distant star ever detected
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star.....»»
Stealth swimmers: The fish that hide behind other fish to hunt
A new study provides the first experimental evidence that the trumpetfish, Aulostomus maculatus, can conceal itself by swimming closely behind another fish while hunting—and reduce the likelihood of being detected by its prey. The study, involving.....»»
Hubble glimpses globular cluster NGC 6652
The glittering, glitzy contents of the globular cluster NGC 6652 sparkle in this star-studded image from the NASA/ESA Hubble Space Telescope. The core of the cluster is suffused with the pale blue light of countless stars, and a handful of particular.....»»
NASA helps spot wine grape disease from skies above California
In a case study, scientists detected the costly infection in cabernet sauvignon grapevines before they showed symptoms visible to the human eye......»»
James Webb image shows the majesty of the most massive known galaxy cluster
A recent image from the James Webb Space Telescope shows the most massive galaxy cluster we know of, one so large that it is nicknamed El Gordo, or the fat one......»»
A solar eruption was detected on Earth, the moon, and even Mars
Scientists recently reported on a solar event that was detectable not only on Earth, but also on the moon and Mars......»»
That time an Air Force sergeant spotted pulsars months before astronomers
Jocelyn Bell-Burnell: "He happened to be a very observant person." Enlarge / Pulsars are spinning neutron stars, the relics of massive stars gone supernova. (credit: NASA's Goddard Space Flight Center) Here's a bit of s.....»»
Astronomers shed new light on formation of mysterious fast radio bursts
More than 15 years after the discovery of fast radio bursts (FRBs)—millisecond-long, deep-space cosmic explosions of electromagnetic radiation—astronomers worldwide have been combing the universe to uncover clues about how and why they form......»»
Towards silver cluster-assembled materials for environmental monitoring
In recent years, there has been a growing interest in using silver nanoclusters (Ag NCs), nanoscale silver particles composed of tens to hundreds of atoms, across various fields like material science, chemistry, and biology. Ag NCs typically have siz.....»»
Two additional exoplanets detected in a nearby planetary system
By conducting radial velocity (RV) follow-up observations of the GJ 367 planetary system with the High Accuracy Radial velocity Planet Searcher (HARPS), an international team of astronomers has detected two additional alien worlds, at least four time.....»»
PFAS detected in blood of horses and dogs too near factory in eastern North Carolina
Debra Stewart walked toward a horse paddock with a bag of carrots in hand. Whisper, a splashed chocolate and white paint horse, met her at the fence......»»
Social media roundup: CSAM on Mastodon; Zuckerberg faces contempt charge; Twitter’s bank plans
An investigation by the Stanford Internet Observatory has found worrying volumes of CSAM on Mastodon. Of particular concern is that the child sexual abuse material included many known examples that should have been automatically detected by digital.....»»
Machine learning and computer vision allow study of animal behavior without markers
With a new markerless method it is now possible to track the gaze and fine-scaled behaviors of every individual bird and how that animal moves in the space with others. A research team from the Cluster of Excellence Center for the Advanced Study of C.....»»
Hubble observes a cluster of boulders around impacted asteroid Dimorphos
Last year, NASA deliberately crashed a spacecraft into an asteroid. Now, Hubble has observed that a number of boulders have been ejected from the asteroid......»»
Study demonstrates consistency of rotational evolution between open cluster and field stars for determining age
Scientists at the Leibniz Institute for Astrophysics Potsdam (AIP) and Boston University have successfully established a connection between the rotation rates of stars in star clusters and those outside them, so-called field stars, enabling the ages.....»»
A tailor-made magnetic vortex: A closer look at a special kind of quasiparticle
Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to researchers because they could be harnessed for new forms of data storage. As theoreticians predicted, there are also so-c.....»»
