Galactic Crash Explains the Small Magellanic Cloud's Mysteries

The SMC's chaotic stellar motions result from a direct passage through the Large Magellanic Cloud in the distant past
University of Arizona researchers used Gaia proper motion data to reconstruct 3D velocities of SMC stars
The collision also helps explain the Magellanic Stream, a vast trail of gas with SMC-matching chemical abundances

Astronomers Find Rare Second-Generation Star From Ancient Universe

Astronomers discovered an extremely rare, iron-deficient second-generation star that formed from a single Population III supernova
The star's chemical fingerprint provides direct evidence of how the universe's first stars seeded heavy elements
Such stars were detected using high-resolution spectroscopy across databases of millions of stellar spectra
The findings help constrain the mass and explosion energetics of the universe's first stellar generation

Scientists Call for SETI to Expand Beyond Narrow Radio Spectrum

A new paper argues that 60+ years of narrow radio/microwave SETI searches have produced no results and the methodology needs rethinking
Authors propose expanding to optical, infrared, gamma-ray, and X-ray frequencies plus broader technosignature detection
Modern machine learning tools make a wider-spectrum search computationally practical for the first time

NASA's X-59 Quiet Supersonic Jet Heads Into Test Flights

NASA's X-59 experimental aircraft is advancing through early test flights as part of the Quesst quiet supersonic mission
The aircraft is designed to produce a 75-decibel sonic thump instead of disruptive booms from conventional supersonic planes
Successful tests could support FAA regulatory changes to allow commercial supersonic flights over land for the first time since the 1970s

Big Bang Matter May Lurk Inside Neutron Stars

Neutron star cores may contain quark-gluon plasma — the primordial state of matter from microseconds after the Big Bang
Gravitational wave data from mergers and NICER X-ray observations provide indirect but consistent evidence
Next-generation detectors like Einstein Telescope could detect post-merger signals carrying quark matter signatures
Confirming quark matter in neutron stars would validate quantum chromodynamics across an extraordinary range of conditions

Robert Goddard's Rocket: 100 Years Since the First Flight

March 16, 2026 marks the 100th anniversary of Robert Goddard's first liquid-fueled rocket flight in Auburn, Massachusetts
The rocket flew for 2.5 seconds, reaching 41 feet altitude and traveling 184 feet in distance
Goddard developed gyroscopic guidance, cryogenic propellant handling, and other innovations that underpin all modern rocketry
From a cabbage patch landing in 1926 to weekly orbital launches today, Goddard's proof of concept set the trajectory
