Every night, astronomers must carefully assess changing weather, the intensity of moonlight and shifting atmospheric conditions before deciding where to point a telescope. It’s a constant balancing act designed to squeeze as much science as possible from every precious hour beneath dark skies. Now, Northwestern University, University of Chicago and Fermilab scientists have developed a […] When astronauts travel deeper into space, every drop of fuel becomes critical, and keeping those fuels stable for months or even years is one of the biggest engineering challenges facing future missions. Now, University of Florida researchers have uncovered a surprising behavior in boiling liquids that could help solve that challenge. Go to Source […] Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy’s outer edge for the first time. The observations confirm it as the largest known galaxy, spanning roughly 520 kiloparsecs, or about 1.7 million light-years, and containing an estimated 3.4 trillion solar masses in stars. The paper was posted […] The formation and evolution of individual stars in a galaxy shape the evolution of the galaxy itself. Stars and stellar remnants make up the vast majority of a galaxy’s mass, so it’s not surprising that the stellar population affects the evolution of galaxies. In the Milky Way’s disk and bulge, stars and dead stars make […] Cislunar space has become the focal point of considerable interest and strategic planning because of the many proposed missions to send crews to the moon in the next decade. These include NASA’s Artemis program, China and Russia’s International Lunar Research Station (ILRS), the European Space Agency’s Argonaut program and others. The long-term goals of these […] There’s a nice kind of irony buried in this story: One of the most sensitive instruments ever built, capable of measuring distortions smaller than the width of a proton, has been quietly held back by something as mundane as heat. And the fix, it turns out, is not some exotic new sensor but a thermal […] In this July 6, 2026, image, NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden activity that shape this unusual system. Go to Source Black holes are often portrayed as cosmic gluttons that swallow everything that comes too close. But new observations of a dramatic black hole outburst—led by Warwick Postdoctoral Fellow Dr. Noel Castro Segura—suggest the reality is much messier. Go to Source How did the first solids that made up planets, moons and asteroids form from the “hot soup” that characterized our solar system’s earliest years? New research from Caltech analyzing pieces of a meteorite has found that, just as snowflakes crystallize around grains of dust, ancient stardust grains left over from long-gone suns may have been […] Every year, thousands of satellites are launched into orbit around our planet. The result is an increasingly congested “space” above Earth populated by equipment that provides services to the surface. At the same time, these satellites affect ground-based astronomy and create the potential for damage when they eventually fall through Earth’s atmosphere to the surface. […] Space isn’t known for rich soil or ideal agricultural conditions anywhere in the solar system. Yet amid extreme temperatures and vast distances, multidisciplinary teams at USF’s Aerospace: Science, Technology, Research and Applications Center (ASTRA) are collaborating on sustainable space agriculture projects with potential applications back on Earth. Go to Source In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet’s main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA’s James Webb Space Telescope (JWST), a team of Caltech researchers has observed […] When astronomers talk about directly imaging an exoplanet orbiting a faraway star, the analogy they most commonly use is trying to spot a firefly next to a massive searchlight. An Earth-like exoplanet is incredibly dim—usually between 100 million and 10 billion times fainter than its host star. Go to Source Amina Helmi’s passion for the Milky Way is clear as soon as one steps into her small office at the University of Groningen, in the north of the Netherlands. Go to Source A simplified machine learning-based low-density lipoprotein cholesterol (LDL-C) equation provides results that are comparable to the original Martin-Hopkins equation, according to a study published online July 15 in JAMA Cardiology.
