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,.....»»
Study using X-Ray telescope indicates that dark energy is uniformly distributed in space and time
When Edwin Hubble observed distant galaxies in the 1920s, he made the groundbreaking discovery that the universe is expanding. It was not until 1998, however, that scientists observing Type Ia supernovae further discovered that the universe is not ju.....»»
Astronomers find distant gas clouds with leftovers of the first stars
Using ESO's Very Large Telescope (VLT), researchers have found, for the first time, the fingerprints left by the explosion of the first stars in the universe. They detected three distant gas clouds whose chemical composition matches what we expect fr.....»»
Uncovering a star"s demise: Supermassive black hole tears apart a giant star
A distant star, dying a fiery and dramatic death, torn apart by a supermassive black hole in a forgotten corner of the sky. One of the most luminous, energetic, long-lasting transient objects didn't blaze through the night sky inspiring legends and l.....»»
This dirt parking lot in the San Gabriel Mountains is a magnet for migrating birds
The San Gabriel Mountains loom like an impregnable fortress for millions of migrating birds making their long and perilous journey to distant breeding grounds in the far north......»»
Where to rent DVDs and Blu-rays as Netflix ends disc rentals
With Netflix sunsetting its DVD-by-mail rental service this September, we've put together this list of some alternative DVD rental options to fill the void......»»
Most people feel "psychologically close" to climate change, find researchers
When spurring action against climate change, NGOs and governmental agencies frequently operate on the assumption that people are unmotivated to act because they view climate change as a problem that affects distant regions far in the future. While th.....»»
New look at "Einstein rings" around distant galaxies just got us closer to solving the dark matter debate
Physicists believe most of the matter in the universe is made up of an invisible substance that we only know about by its indirect effects on the stars and galaxies we can see......»»
Chinese astronomers detect rubidium and samarium in the atmosphere of a distant exoplanet
Using the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO), astronomers from the Chinese Academy of Sciences (CAS) have investigated the atmosphere of MASCARA-4b—a distant "ultra-hot Jupiter" exoplanet. The.....»»
X-ray analysis sheds new light on prehistoric predator"s last meal
We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of X-rays and a team of scientists at The Australian National Un.....»»
African penguins: Climate refugees from a distant past?
Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over 20,000 years ago: In the distance you would see at least 15 large islands—the largest 300 square kilometers in area—swarming with hundreds o.....»»
Netflix will ship its final DVDs this fall
Netflix will stop shipping DVDs and Blu-rays at the end of September 2023, ending a 25-year run that ultimately led it to become the global streaming leader......»»
X-rays reveal electronic details of nickel-based superconductors
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have discovered new details about the electrons in a nickel-based family of superconducting materials. The research, described in two papers published in Physical Revi.....»»

From CERN to Jupiter: Juice embarks on its historic journey
It is not only in the tunnels of CERN that we learn about the origin and composition of the universe. Look up, and space offers the most beautiful phenomena to study: black holes, dark matter, cosmic rays, etc. Studying planets, their structure and t.....»»
How hairs help fish feel and humans hear
By discovering how zebrafish use their hair cells to detect distant movement, a team of Case Western Reserve scientists may have found a path to help explain human hearing loss......»»
Researchers find the key to overcome limits in X-ray microscopy
X-ray microscopes have the advantage of penetrating most substances, so internal organs and skeletons can be observed non-invasively through chest X-rays or CT scans. Recently, studies to increase the resolution of X-ray imaging technology are being.....»»
Laboratory solar flares reveal clues to mechanism behind bursts of high-energy particles
Simulating solar flares on a scale the size of a banana, researchers at Caltech have parsed out the process by which these massive explosions blast potentially harmful energetic particles and X-rays into the cosmos. Their research is published in the.....»»
The man in the monkey nut coat: How a 1940s scientist made "vegan wool" from peanuts
Woolen clothing has been around for as long as humans have been wearing clothes and sheep have been domesticated. Indeed, our distant ancestors used sheep for three things: food, clothing and shelter—wool makes good insulation and helps to keep in.....»»
