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,.....»»
When Greenland was green: Ancient soil from beneath a mile of ice offers warnings for the future
About 400,000 years ago, large parts of Greenland were ice-free. Scrubby tundra basked in the sun's rays on the island's northwest highlands. Evidence suggests that a forest of spruce trees, buzzing with insects, covered the southern part of Greenlan.....»»
Does this exoplanet have a "sibling" sharing the same orbit?
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found the possible "sibling" of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit, which they believe co.....»»
Quantitative analysis of cell organelles with artificial intelligence
BESSY II's high-brilliance X-rays can be used to produce microscopic images with spatial resolution down to a few tens of nanometers. Whole cell volumes can be examined without the need for complex sample preparation as in electron microscopy. Under.....»»
Measuring nanocomposite structures with neutron and X-ray scattering
Experiments with state-of-the-art scattering instruments reveal an absence of specific patterns in the X-rays scattered by nanocomposite materials. With the help of advanced simulation techniques, a new study suggests that attractive interactions bet.....»»
New XRISM satellite mission to study "rainbow" of X-rays
A new satellite called XRISM (X-ray Imaging and Spectroscopy Mission, pronounced "crism") aims to pry apart high-energy light into the equivalent of an X-ray rainbow. The mission, led by JAXA (Japan Aerospace Exploration Agency), will do this using a.....»»
X-rays reveal hidden “first drafts” of ancient Egyptian paintings at Theban Necropolis
Finds include hidden third "ghost hand," alterations to a crown in Ramesses II portrait Enlarge / Portrait of Ramesses II in Nakhtamun tomb, Chief of the Altar in the Ramesseum (possibly 20th Dynasty, circa 1100 BCE). (credit: M.....»»
Scientists discover extensive array of protein folds unexplored in nature
A new study has shed new light on the astonishing diversity of protein structures and their folds in nature. Researchers set out to reveal the extent to which nature has explored the vast landscape of possible protein topologies. The results have unv.....»»
The Webb telescope just offered a revelatory view of humanity’s distant past

Zoom into stunning James Webb image to see a galaxy formed 13.4 billion years ago
The visualization shows a small part of a region called the Extended Groth Strip, covering 5,000 galaxies and zooming in toward the distant Maisie's galaxy......»»
Proof humans reshaped the world? Chickens
When aliens or our distant progeny sift through layers of sediment 500,000 years from now to decode the Earth's past, they will find unusual evidence of the abrupt change that upended life half-a-million years earlier: chicken bones......»»
James Webb spots the most distant active supermassive black hole ever discovered
A very early example of a supermassive black holes was recently discovered, dating back to just 570 million years after the big bang......»»
Webb detects most distant active supermassive black hole to date
It's a bonanza: The universe is absolutely teeming with black holes. Researchers have long known this, but less massive black holes that existed in the early universe were too dim to detect—that is until the James Webb Space Telescope began taking.....»»
Machine learning enhances X-ray imaging of nanotextures
Using a combination of high-powered X-rays, phase-retrieval algorithms and machine learning, Cornell researchers revealed the intricate nanotextures in thin-film materials, offering scientists a new, streamlined approach to analyzing potential candid.....»»
Research group unveils properties of cosmic-ray sulfur and the composition of other primary cosmic rays
Charged cosmic rays, high-energy clusters of particles moving through space, were first described in 1912 by physicist Victor Hess. Since their discovery, they have been the topic of numerous astrophysics studies aimed at better understanding their o.....»»
Webb Telescope detects most distant active supermassive black hole
Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope (JWST). The galaxy, CEERS 1019, existed about 570 million years after the big bang, and its black hole is less massive than any ot.....»»
Quasar "clocks" show the universe was five times slower soon after the Big Bang
Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein's expanding universe. The research is published in Nature Astronomy......»»
