Our understanding of the physical properties of galaxies could be wrong

Up until recently, astronomy was reliant entirely on electromagnetic waves. While that changed with the confirmation of gravitational waves in 2016, astronomers had developed fundamental frameworks in the electromagnetic spectrum by that point.

The search for biosignatures in Enceladus’ plumes

What kind of mission would be best suited to sample the plumes of Saturn’s ocean world, Enceladus, to determine if this intriguing world has the ingredients to harbor life? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC 2025) hopes to address as a team of researchers investigated the pros and cons of an orbiter or flyby mission to sample Enceladus’ plumes.

Supermassive black holes could strip stars down to their helium cores

We all know that black holes can devour stars, rip them apart and consume their remnants. But that only happens if a star passes too close to a black hole. What if a star gets close enough to a star to experience strong tidal effects, but not close enough to be immediately devoured? This scenario is considered in a recent paper on the arXiv preprint server.

An all-sky infrared camera named Dalek continues the search for alien technosignatures

In 2021, the Office of the Director of National Intelligence (ODNI) released a report detailing recently-declassified information on unidentified aerial phenomena (UAP). Since then, the Department of Defense has released annual reports on UAP through the All-domain Anomaly Resolution Office (AARO). Nevertheless, there is still a lack of publicly available scientific data. To address this, a new study led by the Harvard-Smithsonian Center for Astrophysics (CfA) and the Galileo Project proposes an All-Sky Infrared Camera (Dalek) to search for potential indications of extraterrestrial spacecraft.

Scientists discover method to restore vanishing electronic patterns in quantum materials

A new study published in Nature Communications April 7 could reshape the future of magnetic and electronic technology. Scientists at Rice University have discovered how a disappearing electronic pattern in a quantum material can be revived under specific thermal conditions. The finding opens new doors for customizable quantum materials and in-situ engineering, where devices are manufactured or manipulated directly at their point of use.

Astronomy professor offers new theory on universe’s star formation

The universe doesn’t come with an instruction manual—but if it did, University of Missouri Assistant Professor Charles Steinhardt suspects a few pages are missing. Either the universe has been playing by different rules all along, or humanity has been reading the script wrong.

This star might have been thrown out of a globular cluster by an intermediate mass black hole

Black holes come in a range of sizes. Stellar mass black holes form from the collapse of massive stars, typically weighing between 5 and 100 times the mass of our sun, and are scattered throughout galaxies. At the other extreme are the supermassive black holes that lurk at the center of most galaxies, including our own Milky Way.

Scientists discover how stellar-mass black holes emit powerful plasma jets

Black holes are fundamental to the structure of galaxies and critical in our understanding of gravity, space, and time. A stellar mass black hole is a type of black hole that forms from the gravitational collapse of a massive star at the end of its life cycle. These black holes typically have masses ranging from about 3 to 20 times the mass of our sun.

Controlling quantum particle states through structural phase transition of crystals

A research team has successfully fine-tuned the Rabi oscillation of polaritons, quantum composite particles, by leveraging changes in electrical properties induced by crystal structure transformation. Published in Advanced Science, this study demonstrates that the properties of quantum particles can be controlled without the need for complex external devices, which is expected to greatly enhance the feasibility of practical quantum technology. The team was led by Professor Chang-Hee Cho from the Department of Physics and Chemistry at DGIST.

Scientists source solar emissions with largest-ever concentration of rare helium isotope

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the sun. A Southwest Research Institute-led team of scientists sought the source of this unusual occurrence to better understand the mechanisms that drive solar energetic particles (SEPs) that permeate our solar system. SEPs are high-energy, accelerated particles including protons, electrons and heavy ions associated with solar events like flares and coronal mass ejections.
