The Orion Nebula provides a master class in the study of newly born stars as the closest starbirth region to us. Yet, many of its youngest ones are still swaddled in their birth creches, hidden by clouds of gas and dust. The Very Large Baseline Array (VLBA) radio telescopes have managed to punch through the dusty obscuring veil to study a pair of young binary systems called Brun 656 and HD 294300 born in the Nebula. from Universe Today https://ift.tt/LI9WB8y via IFTTT

When NASA's Artemis II crew swung around the Moon in April, the world watched in extraordinary detail and a breakthrough laser communications system was the reason why. Bolted to the outside of the Orion capsule, a compact optical terminal beamed 484 gigabytes of data back to Earth using invisible infrared light, outpacing traditional radio systems by a factor of tens. The result was some of the most vivid imagery ever captured in deep space, and a technology demonstration that will fundamentally change how humanity communicates beyond Earth. from Universe Today https://ift.tt/LY6I7d2 via IFTTT

Our Sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of Sun-like stars are locked in with more than one companion star. If there are two, it’s known as a “binary” system, but in many cases there are even more stars all collectively tied together by gravity. Astronomers have long debated why this happens, and a new paper, available in pre-print on arXiv from Ryan Sponzilli, a graduate student at the University of Illinois, makes an argument for a mechanism known as disk fragmentation. from Universe Today https://ift.tt/8WGdEul via IFTTT
