Distant quasar J0439+1634 explored in X-rays
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on the arXiv pre-print server,.....»»
A solar gravitational lens will be humanity"s most powerful telescope. What are its best targets?
One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed by objects closer to us. Un.....»»
Telescope team-up sees Hubble and Webb working together

Cosmic rays used to track and visualize tropical cyclones offer new perspectives
For the first time, high-energy muon particles created in the atmosphere have allowed researchers to explore the structures of storms in a way that traditional visualization techniques, such as satellite imaging, cannot. The detail offered by this ne.....»»
Study shows gravitational forces deep within Earth have great impact on landscape evolution
Stony Brook University is leading a research project that focuses on the interplay between the evolution of the landscape, climate and fossil record of mammal evolution and diversification in the Western United States. A little-explored aspect of thi.....»»
Scientists collaborate with astronomers around the world to understand distant galaxy
A team of 86 scientists from 13 countries recently carried out extensive high-time resolution optical monitoring of a distant active galaxy, BL Lacertae (BL Lac). Mike Joner, BYU research professor of physics and astronomy, was one of the astronomers.....»»

Hackmanite also changes color upon exposure to nuclear radiation: Memory trace enables new applications
Researchers at the University of Turku, Finland, have long studied the color-changing properties of the natural mineral hackmanite upon exposure to UV radiation or X-rays. Now, the research group is studying the reactions of synthetic hackmanite to n.....»»
LHCf continues to investigate cosmic rays
LHCf has completed its first data-taking period during LHC Run 3, taking advantage of the record 13.6 TeV collision energy. This coincides with the machine's record fill time of 57 hours......»»
Rare fossil teeth overturn long-held views about evolution of vertebrates
An international team of researchers has discovered 439-million-year-old remains of a toothed fish that suggest the ancestors of modern osteichthyans (ray- and lobe-finned fish) and chondrichthyans (sharks and rays) originated much earlier than previ.....»»
