What life on Europa needs

As the years go by, the chances of Europa hosting life seem to keep going down. But it’s not out of contention yet.

Biggest boom since Big Bang: Astronomers uncover most energetic explosions in universe

Astronomers from the University of Hawaiʻi’s Institute for Astronomy (IfA) have discovered the most energetic cosmic explosions yet discovered, naming the new class of events “extreme nuclear transients” (ENTs). These extraordinary phenomena occur when massive stars—at least three times heavier than our sun—are torn apart after wandering too close to a supermassive black hole. Their […]

Universal law of quantum vortex dynamics discovered in superfluid helium

An international research collaboration featuring scientists from the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory has discovered a fundamental universal principle that governs how microscopic whirlpools interact, collide and transform within quantum fluids, which also has implications for understanding fluids that behave according to classical physics.

Symmetry breaking in meniscus splitting: Boundary conditions reveal surprising behavior

Everything in nature has a geometric pattern—from the tiger’s stripes and spirals in flowers to the unique fingerprints of each human being. While these patterns are sometimes symmetrical, most of such patterns lack symmetry, which leaves us with one major question: How do such unsymmetrical patterns emerge in nature?

‘String breaking’ observed in 2D quantum simulator

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics in a two-dimensional analog quantum simulator for the first time. The study, published in Nature, opens up new possibilities for research into fundamental physical phenomena. […]

The heaviest proton emitter: New type of atomic nucleus discovered

For the first time in almost 30 years, the heaviest nucleus decaying via proton emission has been measured. The previous similar breakthrough was achieved in 1996.

What if the Big Bang wasn’t the beginning? Research suggests it may have taken place inside a black hole

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else—something more familiar and radical at the same time?

How physicists used antimatter, supercomputers and giant magnets to solve a 20-year-old mystery

Physicists are always searching for new theories to improve our understanding of the universe and resolve big unanswered questions.

A 1960s idea inspires researchers to study hitherto inaccessible quantum states

Researchers from the Niels Bohr Institute, University of Copenhagen, have created a novel pathway into the study of the elusive quantum states in superconducting vortices. The existence of these was flaunted in the 1960s, but has remained very difficult to verify directly because those states are squeezed into energy scales smaller than one can typically […]

Do the clouds of Venus really host life?

On the surface (you’re welcome for the joke), Venus is not even close to being hospitable to life. But that’s not the end of the story.

NASA Kennedy digs latest robot test

NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) undergoes testing to extract simulated regolith, or the loose, fragmental material on the moon’s surface, inside of the Granular Mechanics and Regolith Operations Lab at the agency’s Kennedy Space Center in Florida on May 27. Ben Burdess, mechanical engineer at NASA Kennedy, observes RASSOR’s counterrotating drums digging […]

Sols 4556-4558: It’s all in a day’s (box)work—Mars rover team assesses boxwork terrain structures

When you are scheduled to participate in Science Operations for the rover’s weekend plan, you know it’s going to be a busy morning. Assembling the activities for Friday through Sunday (Sols 4556 through 4558) was no exception.
