Astronomers lined up under an asteroid"s shadow to measure its size precisely
Astronomers will go to great lengths for science. Recently, dozens of astronomers had the misfortune of traveling to one of the most tempting locales in the southwestern U.S.—Las Vegas. But they weren't there for the city's bright lights—they wer.....»»

Cars, chlamydia threaten Australian koalas
Clinging to a fluffy toy twice her size, orphaned koala joey Ajooni made a snuffling noise as she drank milk from a tiny syringe......»»
Astronomers detect very-high-energy gamma-ray emission surrounding distant pulsar
Using the Large High-Altitude Air Shower Observatory (LHAASO), an international team of astronomers have detected very-high-energy (VHE) gamma-rays around the pulsar PSR J0248+6021, which may be the pulsar's halo or a pulsar wind nebula. The finding.....»»
China"s child policies will increase its future carbon emissions, researchers say
Relaxing its restrictions on family size would make it more difficult for China to achieve its goal to be carbon neutral by 2060, according to a new study by UCL researchers......»»
Scientists discover one of the Earth"s earliest animals in Australian outback
In the shadow of South Australia's largest mountain range beneath the outback soil lies a fossil record that reveals a rich history of life on Earth. Fossils found at Nilpena Ediacara National Park preserve a pivotal moment in the history of evolutio.....»»
Saturn Trojan asteroid confirmed
A small international team of astronomers and astrophysicists has confirmed that asteroid 2019 UO14 is a Trojan asteroid of Saturn. The team has posted a paper describing their study of the asteroid on the arXiv preprint server......»»
Atmospheric oxidation and the creation of modern Mars
Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface then had high rates of meteorite and asteroid impacts from the period known as the Late Heavy Bombardment. But whereas today.....»»
Astronomers observe a strong superflare from giant star
Using the Neutron Star Interior Composition Explorer (NICER) and various ground-based telescopes, an international team of astronomers have performed observations of a strong X-ray superflare which occurred in 2022 on a giant star known as HD 251108......»»
Saturday Citations: All that sparkles is plastic; woke tree diversity; the gravitational basin in which we reside
This week, astronomers considered whether dark energy varies over cosmic timescales. Via neutron analysis, physicists revealed that some Early Iron Age swords were altered recently by swindlers in order to be more historically exciting. And a profess.....»»
Engineering perovskite materials at the atomic level paves way for new lasers, LEDs
Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert electrical charge into lig.....»»
This 40% off 75-Inch Hisense 4K TV will steal the show at your next family gathering
Hisense When it comes to getting a new TV, there’s a mantra that many of us like to follow: bigger is better. 75-inch and over TVs usually have a price tag to match their large size, but thanks to Best Buy’s , that doesn’t have to b.....»»
"Inside-out" galaxy growth observed in the early universe
Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the 'inside-out' growth of a galaxy in the early universe, only 700 million years after the Big Bang......»»
Asteroid mining: A potential trillion-dollar industry
Earth's newest celestial neighbor has finally arrived. Astronomers using a powerful telescope in Sutherland, South Africa, first detected the 33-foot-long asteroid in August, reporting their discovery in Research Notes of the American Astronomical So.....»»
Astronomers find Webb data conflict with reionization models
Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this epoch ended around 1 billion years after the Big Bang......»»
Yes, nature is complex—but saving our precious environment means finding ways to measure it
Nature loss directly threatens half the global economy. The rapid destruction of biodiversity should alarm the many Australian businesses dependent on nature, such as those in agriculture, tourism, construction and food manufacturing. Yet nature cons.....»»
Hurricane Milton Shows How a Storm’s Category Doesn’t Tell the Full Story
Milton’s reclassification to a Category 3 storm suggests it is weakening, but the scale accounts only for wind speed and not hurricane size, storm surge heights, or rainfall—which are all catastrophically large......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
Environmental factors influence Southeast Brazil"s coastal biodiversity more than ecological processes, study finds
Sea surface temperature, wave energy and freshwater discharge from rivers influence the abundance and size of the marine organisms that inhabit rocky shores along the coast of Southeast Brazil more than ecological processes such as competition and pr.....»»
