Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 “bulgeless” galaxies—systems with little or no central stellar bulge. Their paper, published in Monthly Notices of the Royal Astronomical Society, suggests that galaxies without a central bulge grow black holes just as effectively as galaxies that have one—a surprising sign that black holes don’t need galaxy mergers to grow normally.

Once called a “pipe dream,” quantum computers are now approaching practical use. Companies and research institutes around the world are in fierce competition to develop this technology, which has the potential to rapidly perform some calculations that are extremely difficult even for conventional supercomputers.

While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive. But this is what British physicist John Cockcroft and Irish physicist Ernest T.S. Walton had to do in the early 1930s while studying the structure of atomic nuclei. Luckily, their efforts led to their receiving the Nobel Prize in 1951.

Astronomers using Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) Array have found that nearby stars darken toward their edges more strongly at near-infrared wavelengths than predicted by several widely used models of stellar atmospheres, providing a new benchmark for understanding how stars are structured.

On Earth, most of us rarely have to think about the signals that keep our internal clocks aligned. The sun rises, daylight changes, darkness arrives and morning comes again.

As humanity looks toward future bases on the moon, plant cultivation will be critical for sustaining life there. Plants can provide food, oxygen, medicine, water purification and waste recycling, making them indispensable for lunar development.

Imagine a proton catching a wave and surfing it to gain speed. While the imagery may seem wild, the premise of laser-driven ion acceleration has promise as an alternative to conventional accelerators. However, the ultrathin targets used to drive this increase in ion energy are vulnerable to the weak prepulse that precedes the main high-intensity laser pulse, meaning an adaptation in the process is necessary.

EPFL researchers have developed a chip-based laser that keeps a very stable frequency across its tested operating range, without needing active electronic control. Their research is published in the journal Nature Photonics.

Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of radio waves, making them appear to pulse as the beams sweep past Earth.

In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the moon, where NASA’s Artemis program is returning humans, preparing for Mars and shaping the future of space exploration.
