NASA每日天文图片数据集（APOD）包含了NASA每日天文图片计划中的天文图像和解释，这是互联网上运行时间最长的天文科普项目。每个条目都包含一张精选的天文图像或视频，并附有专业天文学家的书面解释。APOD自1995年6月16日起每天发布一个条目，至今已有超过10,000个条目，涵盖了从日常到深奥的各种天文主题。数据集捕获了每个APOD条目的结构化元数据，包括日期、标题、解释文本、媒体URL、版权状态和媒体类型。约70%的条目为NASA或ESA的公共领域图像，其余30%为全球业余天文摄影师的版权作品。该数据集适用于表格分类和文本分类任务。

Daily astronomy images and explanations from NASAs Astronomy Picture of the Day (APOD) program, the longest-running astronomy outreach initiative on the internet. Each entry features a curated astronomical image or video with a written explanation by a professional astronomer. APOD has published one entry every day since June 16, 1995 — an unbroken 30-year record spanning more than 10,000 entries. The subjects range from the mundane to the profound: sunsets, aurora, meteor showers, deep galaxy fields from the Hubble Space Telescope, gravitational wave detections, exoplanet atmosphere spectroscopy, and images from every NASA mission. Each explanation is written in accessible but scientifically accurate language, making the corpus particularly valuable for training and evaluating astronomy language models. This dataset captures the full structured metadata for every APOD entry: date, title, explanation text, media URL, copyright status, and media type. Roughly 70% of entries feature NASA or ESA imagery in the public domain; the remaining ~30% are copyrighted contributions from amateur astrophotographers around the world. The dataset is suitable for tabular classification, text classification tasks.
