CERN has discovered a very charming particle

Enlarge / Particle tracks from the LHCb detector. Brookhaven National Lab The quark model was an intellectual revolution for physics. Physicists were faced with an ever-growing zoo of unstable particles that didn’t seem to have a role in the Universe around us. Quarks explained all that through an (at least superficially) simple set of rules …

The explosive physics of pooping penguins: they can shoot poo over four feet

Enlarge / Bombs away! When approaching a brooding penguin in its nest, it’s best to beware of flying feces. Penguin poo can travel as far as 1.34 meters (about 4.4 feet), a new study finds. Wolfgang Kaehler/LightRocket via Getty Images Nature is a brutal place, so during brooding, chinstrap and Adélie penguins are reluctant to leave …

Europe officially sets its sights on a giant LHC successor

Enlarge / CERN makes its own superconducting wiring for the successor to the LHC. CERN The Large Hadron Collider, the most powerful particle collider humanity has ever built, resides in an enormous, 27-kilometer-long tunnel that extends under the Swiss and French countrysides. What’s often overlooked is that the tunnel was built for an earlier piece …

Astronomers think this black hole collision may have exploded with light

Enlarge / Artist’s concept of a supermassive black hole and its surrounding accretion disk of gas. Embedded within this disk are two smaller black holes, orbiting one another, that eventually collided and may have produced a detectable burst of light. Caltech/R. Hurt (IPAC) One of the most defining characteristics of a black hole is that …

A chilling first: Physicists create exotic “fifth form of matter” on board the ISS

Enlarge / This sequence of false-color images shows the formation of a Bose-Einstein condensate in the Cold Atom Laboratory prototype at NASA’s Jet Propulsion Laboratory as the temperature gets progressively closer to absolute zero, the temperature at which atoms have almost no motion. NASA/JPL-Caltech Physicists at Caltech and the Jet Propulsion Laboratory have created a …

An ancient Roman city has been fully mapped using ground-penetrating radar

Enlarge / Ground-penetrating radar map of the temple in the Roman city of Falerii Novi, Italy. L. Verconck Falerii Novi was once a walled town just north of Rome, likely founded around 241 BC as a relocation site for a Falisci tribe that had rebelled against the Romans. Located on a volcanic plateau, archaeologists surmise …

Astronomers have finally measured the distance of first observed Einstein ring

Enlarge / A radio image of MG 1131+0456, the first observed Einstein ring, taken with the Very Large Array network of radio telescopes. VLA Astronomers around the world may have lost access to their telescopes during the coronavirus pandemic, sheltering in place along with the rest of us, but that hasn’t kept them from advancing …

We now have more evidence that Galileo likely never said “And yet it moves”

Enlarge / Portrait of Galileo Galilei by Justus Sustermans, circa 1640. Galileo Galilei famously stood trial for suspicion of heresy for his insistence—based on astronomical observations through his telescopes—that the Copernican model of the Solar System was correct. The Earth revolved around the Sun, not the other way around, contrary to the Catholic Church’s teachings …

Astronomers have discovered closest black hole yet in trinary star system

Enlarge / Artist’s impression showing orbits of the objects in the HR 6819 triple system. There is an inner binary with one star (orbit in blue) and a newly discovered black hole (orbit in red), as well as a third star in a wider orbit (also in blue). ESO/L. Calçada Astronomers with the European Southern …
