A nebula that extends its hand into space

The Gum Nebula is an emission nebula almost 1400 light-years away. It’s home to an object known as “God’s Hand” among the faithful. The rest of us call it CG 4.

White Sands propulsion team tests 3D-printed Orion engine component

When the Orion spacecraft carries the first Artemis crews to the moon and back, it will rely on the European Service Module contributed by ESA (European Space Agency) to make the journey. The service module provides electrical power generation, propulsion, temperature control, and consumable storage for Orion, up to the moment it separates from the […]

Improving timing precision of millisecond pulsars using polarization

Pulsar timing enables the most stringent tests of fundamental physics. By monitoring the pulse times of arrival (ToAs) of an ensemble of stable millisecond pulsars (MSPs), known as a pulsar timing array (PTA), it is possible to detect nanohertz gravitational waves (GWs). The success of GW detection with PTAs requires the highest possible timing precision. […]

Quantum simulators solve physics puzzles with colored dots

By analyzing images made of colored dots created by quantum simulators, ETH researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for instance in superconductivity.

Hidden citations in physics may obscure true impact

In the scientific literature, a citation acts as a mechanism to signal prior knowledge, enhance credibility, and protect against plagiarism. But it also gives credit to the individual or team who established or discovered the knowledge in question, and citations have thus emerged as a metric to measure the impact of a work or researcher.

Terahertz flexible multiplexing chip enabled by synthetic topological phase transitions

The terahertz band is a gap band between microwave and infrared, and has shown great application potential in many cutting-edge information fields such as 6G communications. Terahertz silicon-based photonics has many advantages such as high transmission efficiency and is an effective platform for realizing terahertz devices.

The interference of many atoms, and a new approach to boson sampling

In daily life, when two objects are “indistinguishable,” it’s due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ball is which as they are passed between the cups. However, at the smallest scales in nature, even the magician cannot tell […]

Strictly no dancing: Researchers discover ‘new molecular design rules’

Since the discovery of quantum mechanics more than a hundred years ago, it has been known that electrons in molecules can be coupled to the motion of the atoms that make up the molecules. Often referred to as molecular vibrations, the motion of atoms act like tiny springs, undergoing periodic motion.
