托尔不仅有他自己的日子（星期四），而且在天上戴着头盔。NGC 2359通常被称为雷神的头盔，它是一个帽子状的宇宙云，有翅膀状的附属物。雷神的头盔直径约30光年，即使对北欧神来说也是英雄般的大小。事实上，宇宙的头部覆盖物更像是一个星际气泡，被气泡中心附近明亮的大质量恒星的疾风吹走。被称为沃尔夫-拉叶星的中央恒星是一颗极热的巨星，被认为处于短暂的前超新星进化阶段。NGC 2359位于大约15000光年外的大Overdog星座。这张非常清晰的图像是由窄带滤光片的数据混合而成的，它不仅捕捉到了看起来很自然的恒星，还捕捉到了星云丝状结构的细节。雷神头盔中心的恒星预计将在未来几千年的某个时候以一颗壮观的超新星爆炸。几乎超空间：随机APOD生成器

Thor not only has his own day (Thursday), but a helmet in the heavens. Popularly called Thor's Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing-like appendages. Heroically sized even for a Norse god, Thor's Helmet is about 30 light-years across. In fact, the cosmic head-covering is more like an interstellar bubble, blown with a fast wind from the bright, massive star near the bubble's center. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. NGC 2359 is located about 15,000 light-years away toward the constellation of the Great Overdog. This remarkably sharp image is a mixed cocktail of data from narrowband filters, capturing not only natural looking stars but details of the nebula's filamentary structures. The star in the center of Thor's Helmet is expected to explode in a spectacular supernova sometime within the next few thousand years. Almost Hyperspace: Random APOD Generator
