How heavy can a neutron star get?

The physics of neutron stars are almost too fantastic to believe: something the weight of two suns compacted to a sphere the size of a city. Each teaspoon of its material would weigh billions of tons. If you’ve done any reading on the topic, you’ve heard these facts before. But despite the intense interest these […]

Terahertz imaging maps spatial chirality in materials with 100-micrometer resolution

In nature, there exist structures that are mirror images of each other but cannot be perfectly superimposed. These are known as chiral objects, derived from the Greek word for “hand,” since left and right hands share the same relationship. Although similar in structure, chiral molecules exhibit different behaviors, and chirality is central to life itself. […]

Violent rocket particles could reshape future spacecraft design

When rockets fire into space, the insides of their engines become an extreme environment where temperatures soar and tiny particles are thrown around at hypersonic speeds. These particles behave in ways that break long-held assumptions, according to new research that could help improve the durability, safety and performance of future space and defense technologies.

Ceres’ surface is much more complex than previously thought

The long, puzzling dwarf planet Ceres, in reality the first named asteroid, has surface features that are much more complex than previously thought. Or at least that’s the conclusion of a recent paper presented at the European Geosciences Union 2026 General Assembly in Vienna.

Small Magellanic Cloud is being pulled apart, reshaping how astronomers read its past

Using more than a decade of observations from the VISTA Survey of the Magellanic Clouds (VMC), researchers measured the motions of millions of stars across the Small Magellanic Cloud with unprecedented precision. The new study, published in Astronomy & Astrophysics, provides direct evidence of a galaxy-wide tidal disruption of the Small Magellanic Cloud from its […]

Rare meteorite provides evidence of giant early planet

Four-and-a-half billion years ago, a massive world—possibly as big as the moon or even Mars—orbited our sun before crashing into another celestial body and shattering into rubble. Now, in a paper published in the journal Earth and Planetary Science Letters, scientists report the first definitive evidence that this lost planetary embryo (protoplanet) existed. Its unique […]

Kamo’oalewa asteroid’s lunar origin challenged ahead of Tianwen-2 arrival

China’s Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo’oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had assumed originated from the moon. However, a new study published in Nature Communications suggests that we may […]

Despite explosion Blue Origin CEO says rocket to fly before year-end

The CEO of Blue Origin vowed its New Glenn rocket “will fly again before the end of this year” after a recent ground test ended in a massive fireball that damaged the launch platform.

‘Mini-Neptune’ exoplanets may have smoggy atmospheres similar to diesel exhaust

The astronauts circling Earth on the Artemis mission sent back beautiful clear photos of the continents, clouds, and oceans. But we might be the exception. Many planets in the universe may be hazed in clouds of soot, according to a new study by University of Chicago scientists. Their analysis explains a curious trend seen by […]

Predicting physics without parameter tuning: A faster computational approach

Numerical simulations in physics often require estimating a multitude of parameters, making the process computationally expensive and complex. Researchers at University of Tsukuba have introduced a new method called the multiparameter eigenvalue-problem emulator, enabling reliable predictions based directly on relationships among known data by eliminating the need for parameter estimation. This innovation considerably reduces computational […]
