A New Map of the Universe, Painted With Cosmic Neutrinos
Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics......»»
Top space telescope from Europe seeks to solve riddles of the universe
EU researchers expect unprecedented insights into galaxies from the study of a mysterious energy force......»»
Radio signals unveil secrets of massive galaxies
Black holes—the cosmic behemoths known for powering some of the brightest radio wave sources in the universe—were the focal point of a study led by Associate Professor Michael Brown, from the School of Physics and Astronomy at Monash University......»»
A six-planet solar system in perfect synchrony has been found in the Milky Way
Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago......»»
Saturday Citations: Adorable kittens, violent pulsars, brand-new fusion reactor and a proposed giant cosmic void
This week in our wrap up, we lull you into a false sense of security with adorable lion cubs then ambush you with terrifying pulsars. We do this not out of a sense of malice but to prepare your mind for the possibility of a giant cosmic void. Also, J.....»»
A new possible explanation for the Hubble tension
The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values......»»
The Universe in a lab: Testing alternate cosmology using a cloud of atoms
We can't experiment with the Universe, but we can make something that works like it. Enlarge / Density waves in a Bose-Einstein condensate. (credit: NASA) In the basement of Kirchhoff-Institut für Physik in Germany, res.....»»
Prototype for DUNE detector will test new technology that can handle more neutrinos
Long before the Deep Underground Neutrino Experiment takes its first measurements in an effort to expand our understanding of the universe, a prototype for one of the experiment's detectors is blazing new trails in neutrino detection technology......»»
Contact binary asteroids are common, but we"ve never seen one form. Now, researchers want to make one
Ever want to play a game of cosmic billiards? That's commonly how the DART mission was described when it successfully changed the orbit of a near-Earth asteroid last year. If you want an idea of how it works, just Google it and an Easter egg from the.....»»
Why don"t we see robotic civilizations rapidly expanding across the universe?
In 1950, while sitting down to lunch with colleagues at the Los Alamos Laboratory, famed physicist and nuclear scientist Enrico Fermi asked his famous question: "Where is everybody?" In short, Fermi was addressing the all-important question that has.....»»
New astrophysics model sheds light on additional source of long gamma-ray bursts
Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows—gamma-ray bursts, or GRBs. The new unified model confi.....»»
For its next trick, Gaia could help detect background gravitational waves in the universe
Ripples in a pond can be captivating on a nice sunny day as can ripples in the very fabric of space, although the latter are a little harder to observe. Using the highly tuned Gaia probe, a team of astronomers proposes in a paper posted to arXiv prep.....»»
If warp drives are impossible, maybe faster-than-light communication is still on the table?
I'm sure many readers of Universe Today are, like me, fans of the science fiction genre. From the light sabers of "Star Wars" to the neuralyzer of "Men in Black," science fiction has crazy inventions aplenty and once science fiction writers dream it,.....»»
Having a single parent doesn"t determine your life chances. Data shows poverty is far more important
Numerous research studies have suggested that children from a single-parent family are worse off than those who have two parents at home. These findings chime with decades of stigma that have painted coming from a single-parent home as undesirable......»»
Researchers pioneer a new way of searching for dark matter
The existence of dark matter is a long-standing puzzle in our universe. Dark matter makes up about a quarter of our universe, yet it does not interact significantly with ordinary matter......»»
From underground detectors to cosmic secrets: Exploring dark matter-nucleon interactions
In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for a thermal relic dark-matte.....»»
New constraints on the presence of ultralight dark matter in the Milky Way
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional experimental meth.....»»
Meet “Amaterasu”: Astronomers detect highest energy cosmic ray since 1991
The Telescope Array in Utah's West Desert picked up a rare particle with 244 EeV energy. Artist’s illustration of extensive air showers induced by ultra-high-energy cosmic rays. Credit: Toshihiro Fujii/L-INSIGHT/Kyoto.....»»
Telescope Array detects second-highest-energy cosmic ray ever
In 1991, the University of Utah Fly's Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray's energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and th.....»»
A galaxy only 350 million years old has surprising amounts of metal
Astrophysicists working with the JWST have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang. How does that fit in with our understanding of the universe?.....»»
Does spaceflight increase men"s risk of erectile dysfunction?
During missions into space, astronauts are exposed to high levels of galactic cosmic radiation and weightlessness. Simulation experiments in male rats indicated that these aspects of spaceflight can negatively affect vascular tissues relevant to erec.....»»
