Finding an Earth-like world beyond the solar system is the holy grail of exoplanet research, and the field has seen remarkable technological advances in detecting and studying exoplanets since the first confirmed exoplanet around a sun-like star was discovered in 1995. These advances include ground- and space-based telescopes, notably the James Webb Space Telescope. Although […]
The Earth is surrounded by an invisible barrier that was thought to prevent highly energetic electrons from reaching closer to our planet. But in 2024, Japan’s Arase space probe detected these electrons well inside the barrier. Now, research led by Nagoya University has found evidence that the electrons were accelerated locally rather than infiltrating from […]
Using a new slow-motion electron camera, physicists from Regensburg, Marburg and Jülich revealed how intense electric fields drive electrons in graphene, causing them to jump across energy gaps in a seemingly paradoxical manner. This was made possible by a novel combination of laser technology and electron microscopy.

More than a century after Einstein first devised the equations that describe gravity, physicists are still finding new ways of interpreting them. Luca Comisso, an associate research scientist in Columbia University’s departments of Astronomy and Physics and the Columbia Astrophysics Laboratory, and Felipe A. Asenjo of Universidad Adolfo Ibáñez in Chile, recently found a new […]
Researchers at Delft University of Technology (the Netherlands) have succeeded in controlling the magnetism in the nucleus of a single atom with radio waves. This came as a surprise: until now, physicists believed that this nuclear spin could not be manipulated directly. The discovery could open up new possibilities for storing and reading quantum information. […]
When two objects touch and then separate, they can swap tiny amounts of electric charge, even if they are made from exactly the same material. This ‘triboelectric effect’ is the source of everyday static electricity, but it is still poorly understood in large samples of powder, where vast numbers of particles are constantly colliding with […]
The theory that comets delivered the molecular building blocks for life on Earth is a long-standing one, since comets are known to carry many of these molecules. However, a new study challenges this idea.

Hula hooping may be literal child’s play, but as it turns out, the physics behind the gym-class staple is so complicated that scientists have spent decades trying to understand how the hula hoop defies gravity.

Scientists may add a new dwarf planet to the official roster of our solar system. The distant, icy body, provisionally dubbed 2026 ED138, orbits our system beyond Pluto. It was spotted earlier this month by a scientist combing through data from the Simonyi Survey Telescope at the NSF-DOE Vera C. Rubin Observatory.

In nonreciprocal active matter, agents act differently on each other, seemingly in violation of Newton’s third law. This principle can result in various active matter traits, such as self-propulsion, molecular regulation and collective motion.
