Researchers from the University of Oxford, Google Cloud, and Radboud University (Netherlands) have demonstrated that a general-purpose AI model, <strong>Gemini<\/strong>, can accurately identify and classify real celestial phenomena (supernovae, black holes, asteroids, or stellar flares) without specialized training.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">This achievement is not based on a model designed for astrophysics, but on a Gemini-type large language model (LLM), similar to those used in natural language processing. By guiding it with a few instructions, the researchers transformed it into a cosmic observation assistant capable of explaining its decisions and justifying the classification of an astronomical event.<\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-1\" style=\"color:#986e13\">Artificial Intelligence Takes to the Skies<\/h2>\n\n<p class=\"text-justify wp-block-paragraph\">Traditionally, the detection of celestial events relies on specialized models that learn to recognize light patterns or temporal sequences in telescope data. These tools often require several million annotated images and weeks of computation on supercomputers.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">Gemini is a game-changer. When presented with simple images or descriptions based on observations, the AI was able to identify several types of phenomena with an <strong>average accuracy of 92%<\/strong>, according to researchers at Oxford<sup><a href=\"#ref1\">1<\/a><\/sup>. In particular, it recognized:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>a <strong>supernova<\/strong> (the explosion of a star at the end of its life),<\/li>\n\n\n\n<li>a <strong>black hole tearing apart a passing star<\/strong>,<\/li>\n\n\n\n<li>a <strong>fast-moving asteroid<\/strong>,<\/li>\n\n\n\n<li>and a <strong>brief flash of light from a compact star system<\/strong>.<\/li>\n<\/ul>\n\n<p class=\"text-justify wp-block-paragraph\">Without any complex training phase or specific tuning, the model was able to explain its reasoning\u2014for example, by describing how a signal\u2019s brightness, trajectory, or spectral signature indicated a specific type of astrophysical event.<\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-2\" style=\"color:#986e13\">A collaboration between science and artificial intelligence<\/h2>\n\n<p class=\"text-justify wp-block-paragraph\">According to Professor <strong>Chris Lintott<\/strong>, an astrophysicist at the University of Oxford and co-author of the study, this approach ushers in a new era for research:<br\/><em>\u201cWe have shown that a general-purpose AI, with minimal guidance, can become a reliable scientific tool. This transforms the way we analyze the cosmos.\u201d<\/em><\/p>\n\n<p class=\"text-justify wp-block-paragraph\">The researchers used Gemini within <strong>Google Cloud Vertex AI<\/strong>, Google\u2019s scientific computing platform. This collaboration enabled the processing <strong>of<\/strong> more than <strong>12 million astronomical images<\/strong> from telescopes located in Europe, Hawaii, and Chile.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">The results show that a general-purpose language model can compete with\u2014and sometimes outperform\u2014specialized systems, while maintaining a high degree of explainability and adaptability.<\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-3\" style=\"color:#986e13\">When the sky becomes a laboratory for AI<\/h2>\n\n<p class=\"text-justify wp-block-paragraph\">Modern astronomy produces a colossal amount of data. Every night, observatories around the world generate more than <strong>150 terabytes<\/strong> of data from optical and radio sensors<sup><a href=\"#ref2\">2<\/a><\/sup>. Yet barely <strong>5% of the observed phenomena<\/strong> are actually classified or studied.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">Gemini is changing the game. Thanks to its ability to interpret multimodal data (images, spectra, textual descriptions), it enables astronomers to identify rare or previously unobserved signals and formulate new hypotheses more quickly.<br\/>AI no longer merely observes; it engages with science: it explains its observations, justifies its detections, and suggests new areas of investigation.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">According to <strong>Delphine Houlden<\/strong>, an astrophysicist at Radboud University:<br\/><em>\u201cFor the first time, a general-purpose AI understands our scientific language and can engage with us in discussions about real-world phenomena. It\u2019s no longer a black box; it\u2019s a research partner.\u201d<\/em><\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-4\" style=\"color:#986e13\">Toward the &#8220;Astronomization&#8221; of General-Purpose AI<\/h2>\n\n<p class=\"text-justify wp-block-paragraph\">This experiment demonstrates that a multimodal language model can be transformed into a context-aware scientific expert. With just a few instructions, it can adopt the reasoning of an astronomer and recognize the telltale signs of rare events.<\/p>\n\n<p class=\"wp-block-paragraph\">This approach could be applied to other disciplines.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>In <strong>meteorology<\/strong>, to forecast extreme weather events.<\/li>\n\n\n\n<li>In <strong>geophysics<\/strong>, to identify seismic signals.<\/li>\n\n\n\n<li>In <strong>medicine<\/strong>, to detect abnormalities in complex imaging.<\/li>\n<\/ul>\n\n<p class=\"text-justify wp-block-paragraph\">According to Google Research, the use of versatile models like Gemini could <strong>reduce the time required for scientific analysis by 40%<\/strong> across several fields by 2030<sup><a href=\"#ref3\">3<\/a><\/sup>.<\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-5\" style=\"color:#986e13\">Ethical and epistemological issues<\/h2>\n\n<p class=\"wp-block-paragraph\">The introduction of general-purpose AI into research raises significant questions:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Reliability<\/strong>: How can we verify the assumptions of an AI system that reinterprets complex data?<\/li>\n\n\n\n<li class=\"text-justify\"><strong>Bias<\/strong>: Can a model trained on human data accurately interpret unknown astrophysical phenomena?<\/li>\n\n\n\n<li><strong>Role of the researcher<\/strong>: humans become the guardians of reasoning, responsible for interpreting and validating the results.<\/li>\n<\/ul>\n\n<p class=\"text-justify wp-block-paragraph\">The study\u2019s authors emphasize the importance of <strong>cross-validation<\/strong>. Gemini is not a replacement for astronomers, but rather a tool designed to speed up their work. Its main strength lies in its ability to quickly sift through massive amounts of data while providing an explanation for its decisions.<\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-6\" style=\"color:#986e13\">A New Horizon for Research<\/h2>\n\n<p class=\"text-justify wp-block-paragraph\">This collaboration between Oxford, Google Cloud, and Radboud University marks a symbolic milestone: general-purpose AI is no longer limited to conversational applications; it is becoming a tool for scientific discovery.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">The idea of artificial intelligence that learns to \u201cread the sky\u201d perfectly illustrates the new dynamic of AI-assisted science. Gemini does not replace human observation; rather, it expands upon it, complements it, and puts it into context.<\/p>\n\n<p class=\"text-justify wp-block-paragraph\">Thanks to models like this one, researchers hope <strong>to increase the detection rate of supernovae and transient events by 25%<\/strong> over the next few years<sup><a href=\"#ref4\">4<\/a><\/sup>. By giving astronomers a new digital eye, AI doesn\u2019t just look at the sky\u2014it helps us understand what\u2019s happening there.<\/p>\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-7\" style=\"color:#0064c6\">Learn more<\/h2>\n\n<p class=\"text-justify wp-block-paragraph\">Delve deeper into the <strong>ethical foundations and cultural implications<\/strong> of artificial intelligence with two must-read articles from the <em>aivancity<\/em> blog.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/preprod.aivancity.ai\/blog\/en\/generative-ai-just-the-tip-of-the-iceberg\/?utm_source=chatgpt.com\">Generative AI: Just the Tip of the Iceberg<\/a><\/strong><br\/>An analysis of the hidden capabilities of artificial intelligence models, reminding us that science, creativity, and our understanding of the world\u2014whether terrestrial or celestial\u2014are merely the first manifestations of a potential that remains largely unexplored.<\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>7 Ethical Principles for Trustworthy Artificial Intelligence<\/strong><br\/>This article explores the essential guidelines that must accompany any technological advancement, such as that embodied by Gemini, to ensure AI that is responsible, transparent, and respectful of humanity.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading text-justify has-text-color has-link-color wp-elements-8\" style=\"color:#5a5e83\">References<\/h3>\n\n<p id=\"ref1\" style=\"text-align:justify;\">1.
