MAGOS: Hot Cores in the LMC Reveal Subsolar Chemistry in Star Formation
Overview: MAGOS maps hot cores in a metal-poor neighbor The Magellanic Outflow And Chemistry Survey (MAGOS) targets the Large Magellanic Cloud (LMC) to explore how massive protostellar environments develop under subsolar metallicity. By surveying a sample of hot cores around 30 massive protostellar objects, the study investigates the chemical inventory, excitation conditions, and spatiotemporal evolution…

MAGOS: Hot Cores in the LMC — A Subsolar Chemistry Study
Introduction: Why the LMC Matters for Hot Core Studies The MAGellanic Outflow And Chemistry Survey (MAGOS) targets the Large Magellanic Cloud (LMC) to probe hot cores around massive protostellar objects under subsolar metallicity. The LMC’s proximity offers a unique laboratory to study how chemistry and early star formation unfold when heavy elements are less abundant…

Unprecedented Milky Way Radio View Takes 40,000 Hours to Build: Space Photo of the Week
Overview: A Radio Window into Our Galaxy Humans have long wondered what the Milky Way looks like when viewed from the inside out. Since we inhabit one of its spiral arms, imaging the entire galaxy in a single photograph is impossible. Instead, astronomers piece together a mosaic of radio signals captured from Earth and space-based…

Rogue Planet Glutton: A Runaway World Eating Gas Like a Star
Introduction: A Planet That Breaks the Rules In a surprising twist to our understanding of planetary physics, astronomers have identified a rogue planet that behaves more like a star than a typical world. Unlike the planets in our solar system, which orbit stars or drift in quiet solitude, this runaway planet appears to be devouring…

Cosmic Bat Emerges in Halloween Sky: A Nebula Unfolds Its Wings
A Halloween Highlight from the Cosmos Astronomers have captured a striking new image of a bat-shaped nebula unfurling its luminous wings in deep space, timed to delight stargazers as Halloween approaches. Located roughly 10,000 light-years from Earth, this celestial silhouette stretches across the constellations Circinus and Norma, offering a rare glimpse into the dramatic processes…

We Ain’t Seen Nothing Yet: Exploring the Real Quiet of Space
The illusion of emptiness: is space truly empty? When we talk about the vastness of space, the word empty often comes to mind. Yet the real cosmos is not a perfect void. Even in the most distant regions, pockets of matter and energy whisper through the vacuum. From the International Space Station to the edge…

We Ain’t Seen Nothing Yet: The Real Empty Space of Our Solar System
The Myth of Cosmic Vacuum When people imagine space, they often picture a perfect, absolute void. But in truth, the space between worlds is crowded with a surprising mix of matter and energy. From our own backyard around the International Space Station to the vast stretches between stars, “empty” space is a relative term that…

VUV Spectra of Ice Isoprene Reveal ISM Signatures at 10 K
New findings on the VUV spectra of icy isoprene and terpenes Isoprene and its related terpenes are key organic molecules in many astrochemical environments. From the vastness of the interstellar medium (ISM) to the icy surfaces of solar system bodies, these compounds are expected to exist but have remained only partially characterized. A recent study…

First Detection of Ethylene Oxide and Acetaldehyde in Hot Core G358.93−0.03 MM1
Introduction to Ethylene Oxide and Acetaldehyde Ethylene oxide (c-C2H4O) and acetaldehyde (CH3CHO) are notable organic molecules that play a critical role in the chemistry of the interstellar medium (ISM). Their presence in hot molecular cores could offer insights into the complex processes that lead to the formation of amino acids, the essential building blocks of…

First Detection of Ethylene Oxide and Acetaldehyde in G358.93−0.03 MM1
Introduction to Ethylene Oxide and Acetaldehyde Ethylene oxide (c-C2H4O) and acetaldehyde (CH3CHO) are complex organic molecules that hold significant importance in astrochemistry. These molecules are believed to be crucial in the formation of amino acids within the interstellar medium (ISM), which may ultimately have implications for the origins of life as we know it. The…
