Nova eruption of V1716 Sco inspected in X-rays and gamma rays
Astronomers from China and Taiwan have observed the nova eruption of V1716 Sco that took place last year, using various X-ray and gamma-ray space observatories. Results of the observational campaign, presented June 27 on the preprint server arXiv, pr.....»»
Counting rays: Aerial surveys reveal ample populations in southeast Florida
The whitespotted eagle ray (Aetobatus narinari) and the giant manta ray (Mobula birostris) are rapidly declining globally. Both species are classified by the International Union for Conservation of Nature as endangered worldwide, and the giant manta.....»»
Further study of bright gamma-ray burst GRB 230307A shows it was caused by neutron stars merging
An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their study, published in the j.....»»
LHAASO discovers giant ultra-high-energy gamma-ray bubble, identifying the first super PeVatron
The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin of cosmic rays with energy higher than 10 Peta-Elec.....»»

On Hawaii"s Kilauea, little stresses add up
Hawaii's Kilauea volcano is one of the most active in the world. Its eruption in 2018 was its largest in 200 years and among the costliest volcanic disasters in U.S. history. Devastating as it was to the Hawaiian landscape, Kilauea's eruption proved.....»»
Gamma-ray bursts: Harvesting knowledge from the universe"s most powerful explosions
The most powerful events in the known universe—gamma-ray bursts (GRBs)—are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our sun. Now thought to announce t.....»»
NASA"s laser navigation tech to enable commercial lunar exploration
Later this month, NASA's commercial lunar delivery services provider Intuitive Machines will launch its Nova-C lunar lander carrying several NASA science and technology payloads, including the Navigation Doppler Lidar (NDL). This innovative guidance.....»»
Extreme eruption on young sun-like star signals savage environment for developing exoplanets
Astronomers have detected an extreme eruption from a young star that became more than a hundred times brighter in only a few hours. This discovery offers new insight into how young sun-like stars behave early in their lives, and their impact on the d.....»»
AI reads ancient scroll buried by Vesuvius eruption
Three researchers on Monday won a $700,000 prize for using artificial intelligence to read a 2,000-year-old scroll that was scorched in the eruption of Mount Vesuvius......»»
Machine learning techniques enhance the discovery of excited nuclear levels in sulfur-38
Fixed numbers of protons and neutrons—the building blocks of nuclei—can rearrange themselves within a single nucleus. The products of this reshuffling include electromagnetic (gamma ray) transitions. These transitions connect excited energy level.....»»
