For decades, astronomers were only able to study the universe’s very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence to date for these ancient “Population III” stars, finding them clustered around a small companion object that formed just 400 million years after the Big Bang.

We’ve spent decades scratching the surface of Mars trying to uncover life there. But we’ve been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it’s likely that it’s been too hostile to harbor extant life. So if we want a better shot at finding currently living life on Mars, we need to go underground. That is exactly the purpose of Orpheus, a proposed Mars vertical takeoff and landing (VTOL) hopper mission put forth in a paper presented by Connor Bunn and Pascal Lee of the SETI Institute at the 57th Lunar and Planetary Science Conference (LPSC).

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their own characteristic masses, spin behavior, and merger rate that may be linked to different dominant formation mechanisms. The paper outlining their results was submitted to the preprint server arXiv on March 18.

A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast charged particle (Bragg peaks), have been used to detect this kind of ordering. Prior to this study, there had been no direct, high-resolution in situ imaging of cavity-induced density-wave order in ultracold gases.

A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through collective excitations of the system called quasiparticles.
