✨ Compact Quadruple Star Discovered

Penn State astronomers and an international team used the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) to create the largest 3D map of excited hydrogen emissions from the universe 10 billion years ago.

The team employed Line Intensity Mapping on half a petabyte of HETDEX data, charting the distribution of Lyman alpha radiation to reveal previously unknown faint galaxies and vast intergalactic gas structures.

This map illuminates the "cosmic noon," a period of vigorous star formation, tracing how galaxies interacted with surrounding gas, which according to Penn State's Donghui Jeong, is central to understanding star buildup.

NASA (National Aeronautics and Space Administration) technicians at Kennedy Space Center successfully repaired a critical helium flow obstruction on the Artemis II Space Launch System (SLS) rocket, advancing preparations for its crewed lunar mission.

Engineers identified and replaced a dislodged seal within a quick disconnect mechanism on the launch vehicle stage adapter, which had blocked helium flow to the rocket's upper stage during a February 21 test.

This crucial repair keeps the Artemis II mission on track for a potential April launch, ensuring the SLS rocket and Orion spacecraft are fully functional for the first crewed flight around the Moon.

NASA (National Aeronautics and Space Administration) and ESA (European Space Agency) astronomers combined observations from the Hubble and Euclid space telescopes to create a stunningly detailed new image of the Cat's Eye Nebula.

Euclid’s wide-field near-infrared and visible light view captured the nebula's outer halo, while Hubble’s new high-resolution visible-light image revealed concentric shells and jets of high-speed gas at its core.

This composite image provides a cosmic "fossil record" of the central star's final evolutionary stages, placing the nebula's intricate structure within the vast cosmic context that both telescopes are designed to explore.

University of Kansas astrophysicist Mikhail Medvedev presented new research solving the longstanding mystery of the distinct "zebra stripe" pattern observed in radio wave emissions emanating from the famous Crab Pulsar.

Medvedev's model shows a cosmic "tug-of-war" where the pulsar’s magnetospheric plasma acts as a defocusing lens while gravity acts as a focusing lens, creating in-phase and out-of-phase interference bands.

This represents the first real-world application of this combined plasma-gravity lensing effect, offering a new tool to probe matter distribution around neutron stars, according to Medvedev's paper in the Journal of Plasma Physics.

An international research team using TESS (Transiting Exoplanet Survey Satellite) data has discovered and analyzed TIC 120362137, now confirmed as the most compact 3+1 type quadruple stellar system ever found.

The system features an inner binary with a 3.28-day period, a third star orbiting at 51.3 days, and a fourth star with a 1046-day outer orbital period, all confirmed via spectro-photodynamical analysis.

This planetary-system-like configuration provides a unique laboratory for studying star formation and dynamical evolution, with evolutionary models suggesting the system will likely end its life as a pair of white dwarfs.
