Using the James Webb Space Telescope (JWST), a team of astronomers identified 104 magnified stellar events in a galaxy known as the Dragon, located around 6.5 billion light-years away. This discovery more than doubles the previous record of 44 such detections…
The laws of physics at the quantum level can break free from the standard confines of solids, liquids, and gases, and researchers just observed an exotic quantum state of matter – a particular way of particles organizing and behaving themselves.
Astronomers have identified a new class of mysterious hypersoft X-ray source that behave unlike anything catalogued before.
Primordial black holes are hypothetical objects that could have formed directly from dense clumps of matter in the very early universe. If they exist, their dramatic origins would set them apart from the black holes we see today, which form when massive stars…

Tuning in to electronic noise can tell us whether electrons have paired up or not.
NASA's Swift Observatory went out in a blaze of glory this week, but it left behind millions of images of the universe that could fuel discoveries for decades.
An astrophysicist tells NewsNation a large object striking the International Space Station would be "devastating."
A nuclear explosion might save Earth from a deadly asteroid, but new research suggests that hitting the wrong side could make the difference between success and disaster. Scientists found that an asteroid's irregular shape can dramatically affect how it …

Ria Webb is among record levels of women freezing their eggs in the hope of later having a family.
It's almost the New Moon.
Rockets certainly have a substantial impact if you ever see a launch in person. The noise, shock waves, and even heat can be awe-inspiring. What is less obvious are the impacts a launch has on our …
Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics hundreds of th…
Most asteroids are pretty predictable.
In a new Nature Physics study, researchers demonstrated the Aharonov-Bohm effect in a quantum simulation of a lattice gauge theory using a hybrid trapped-ion quantum computer.
MBARI’s first 4K footage of a barreleye fish offers a rare chance to study how its unusual eyes work in the ocean’s dim twilight zone.
A new study points to testosterone and proteins in the skin as reasons why males and females experience temperatures differently.
Glaciers are often thought of as unyielding blocks of ice that slowly carve out the landscape as they move downhill by gravity. But sometimes their slow crawl becomes a surge that sees them move orders of magnitude faster than their usual speed.
Now we finally know where it went
NASA is asking the public to send their names to Titan for an ambitious mission that will see a flying craft explore the Saturn moon in 2034, if all goes according to plan.
An alternative model in which the universe is 26.7 billion years old and needs neither dark matter nor dark energy has held up against several major cosmology tests, according to a new University of Ottawa study. The research, titled "A Big Bang Nucleosynthes…
Researchers suggest gas is being released from hot magma deep beneath Mars' surface after discovering intriguing new fissures.
"I think the implications are pretty severe, which is why we're taking it so seriously and putting such extreme focus on the mission right now."
Earth has acquired a temporary companion in space, but it will not stay for long.
The surest way to get a scratch from a feline is to go for a forbidden tummy rub. But why do cats hate being touched on their bellies?
The decades old idea that our solar system’s Oort Cloud is continually perturbed by a heretofore undetected low mass Red Dwarf star remains the best explanation for periodicities found in Earth’s impact record. Or so says a well known physicist who has long c…
Camp Century was built in Greenland during the Cold War. More than 60 years later, climate scientists have discovered materials to research there.
Few insects have a more gruesome lifestyle than Darwin wasps. Rather than simply hunting other animals, these parasitic wasps lay their eggs on or inside living hosts, including caterpillars, beetles and spiders. Their larvae then feed on their hosts, gradual…
Traditional lenses and mirrors focus light using curved surfaces. Metasurfaces can achieve similar functions with a flat layer of nanoscale structures that locally control the phase of light. Extending these flat optics into the ultraviolet could support comp…
Spotted a dazzling light in the eastern sky before sunrise? It's Venus, and the planet is only going to get brighter as it heads toward its spectacular peak later this month.
Wildfires from decades ago may be secretly melting the frozen ground from below, setting off a disastrous chain of events in the present.
Artificial intelligence is helping Texas A&M AgriLife Research scientists fast-track answers to a long-standing question in human biology: What do hundreds of mystery proteins in the mitochondria actually do?
A team of artificial-intelligence agents simulates a laboratory of robots and instruments to ensure that the physical workspace functions smoothly and then directs that workspace’s operations.
"We showed that we can actually recover a planet that people previously couldn’t see."
A robotic truss builder that was conceived, designed and built by Caltech researchers has successfully built a structure in space—without the help of astronauts—for the first time. The truss builder, part of DARPA's Novel Orbital and Moon Manufacturing, Mater…
A radio signal from a star 238 light-years away briefly looked like it might be a sign of alien life, but the astronomers who found it say it’s more likely c...
