Inside some fusion energy systems, particles hotter than the core of the sun can become unruly in a few thousandths of a second, far faster than any human operator can react. A new software framework developed by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University hands those […]
The Cluster mission danced its final dance as Tango reentered the atmosphere Sept. 1 at 11:30:31 p.m. CEST. The end of the Cluster mission in 2024 marked the start of the reentry data-collection campaign. After four targeted reentries, this is now a proven method of safe end-of-life disposal. It also enabled repeated observation of the […]
High above Earth, thin veils of metallic haze drift through the edge of space. Known as sporadic E layers, these high-altitude “clouds” form from the vaporized dust of burned-up meteors, earning their name from the unpredictable way they emerge and then dissipate. Now, new results from a NASA sounding rocket—a suborbital research rocket—that flew five […]
An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental principle at the heart of Einstein’s theory of gravity remains consistent with the behavior of matter in the quantum world. The study, […]
Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as “ghostly” for their near-zero mass and elusive nature, as they have very little interaction with normal matter.

Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported from the cold outer regions of the planetary system to regions where planets form.

Nā ʻUhane Māhoe Huki Pū i ke Ola is the Hawaiian name given to NGC 7253—a pair of spiral galaxies caught in each other’s gravity. Captured by the Gemini North telescope on Maunakea in Hawai’i, the image created a spectacular symbolic display for this year’s interns participating in Project Hōkūlani.

A 13-meter (43-foot) Falcon 9 rocket stage struck the moon last month, leaving a crater about 20 meters (66 feet) wide. In the days before impact, University of Tasmania researchers from the School of Natural Sciences were the first in the world to detect the object by radar, helping refine predictions of where it would […]
The weak equivalence principle (WEP) is central to Einstein’s general relativity. It posits that gravity must accelerate everything equally, regardless of what it is made from. For the first time, a team led by Ming-Sheng Zhan at the Wuhan Institute of Physics and Mathematics has tested the principle using clouds of continuously free-falling atoms aboard […]
Astronomers have discovered a second interstellar cloud near the center of the Milky Way that is extraordinarily rich in complex molecules, including several molecules associated with prebiotic chemistry. The newly studied cloud, G+0.633-0.0604, or G+0.633, contains more than 120 identified molecular species and is the first confirmed chemical twin of another famous molecule-rich cloud. Their […]
When Blue Origin’s New Glenn launch vehicle accidentally exploded during a static test fire in May 2026, the explosion generated low frequency soundwaves below the range of human hearing.
