Planetary scientists believe they can now predict the green glow of an aurora in the night sky above Mars, and they have the images to prove it. Go to Source An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound binary, designated MML 48, consists of two young low-mass stars. The finding will be published in the upcoming issue of the Astronomy & Astrophysics journal. Go to Source A greedy white dwarf star not far from Earth is devouring its closest celestial companion at a rate never seen before, space scientists have discovered. Their study found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Go to […] A new AI-powered tool has reduced astronomers’ workload by 85%—filtering through thousands of data alerts to identify the few genuine signals caused by supernovae (powerful explosions from dying stars). The findings are published in The Astrophysical Journal. Go to Source Extremophiles are a favorite tool of astrobiologists. But not only are they good for understanding the kind of extreme environments that life can survive in, sometimes they are useful as actual tools, creating materials necessary for other life, like oxygen, in those extreme environments. A recent paper from Daniella Billi of the University of Rome […] A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The gamma-ray bursts from outside the Milky Way galaxy repeated several times over the course of a day. Gamma-ray bursts (GRBs) are the most powerful explosions in the universe, normally caused by the catastrophic destruction of stars, but no […] A Southwest Research Institute-led team has reported the first detection of gas on the distant dwarf planet Makemake, using NASA’s James Webb Space Telescope (JWST). This discovery makes Makemake only the second trans-Neptunian object, after Pluto, where the presence of gas has been confirmed. The gas was identified as methane. Go to Source […] Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, Saturn, and gas planets like them orbiting other stars? A new study using observations from NASA’s James Webb Space Telescope sheds light on this question by focusing on a peculiar object that astronomers discovered by […] The eyes of every astronomer widened this year when an interstellar traveler was discovered in our solar system. Go to Source Over the course of more than two decades, researchers at the University of Bern have developed the so-called “Bern model,” a suite of computer programs that can numerically simulate the formation of planetary systems, thus shedding light on system architecture. These models are, however, very complex: each simulation from the Bern model can take a […] Since the dawn of human spaceflight, scientists have carefully studied the effects of space and microgravity on astronauts. After decades of observations and examinations, one truth is certain: space is brutal on the human body. Muscles atrophy, bones lose mass, limbs stretch and—more unknown—eyesight can degrade in ways not yet fully understood. Go to Source […] Last week, the Perseverance rover began an exciting new journey. Driving northwest of the Soroya ridge, Perseverance entered an area filled with a diverse range of boulders that the science team believes could hold clues to Mars’s early history. Go to Source A SpaceX launch on the Space Coast just after sunset Monday could mean the return of the unique jellyfish effect over Florida’s skies. Go to Source Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), and her team have posted a new paper to the arXiv preprint server that for the first time uses binary and solitary pulsars to constrain properties of a dark matter sub-halo in our own […] Astronomers have discovered “dust-shrouded supermassive black holes” in the early universe, less than 1 billion years after the Big Bang—a type of object that had previously escaped detection.
