First people thought they were seeing a [massive crab](http://time.com/3982146/mars-crab-monster/ "undefined") on Mars, and now it’s a ghostly woman. [Thanks to TIME’s science writer Jeffrey Kluger](http://time.com/3982146/mars-crab-monster/ "undefined"), we know the sights are actually due to pareidolia; a phenomenon that makes us see all sorts of things that aren’t really there. It’s when people see familiar images in unfamiliar patterns. In a story explaining the large crab on Mars image, [Kluger writes](http://time.com/3982146/mars-crab-monster/ "undefined"): --- > “” --- So no, there’s not a ghost woman on Mars, and there’s no giant crab, but it’s probably not the last time there’s a “sighting” of something unusual on the planet. **MORE:** [Why Your Brain Thinks This Picture Shows a Giant, Martian Crab Monster](http://time.com/3982146/mars-crab-monster/ "undefined") \[[_Mashable_](http://mashable.com/2015/08/06/nasa-mars-lady/?utm%5Fcid=mash-com-fb-main-link "undefined")\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3990437/mars-ghost-crab/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3990437/mars-ghost-crab/"},"headline":"You're Not Actually Seeing A Ghost on Mars","datePublished":"2015-08-10T14:52:49.000Z","dateModified":"2026-04-13T07:23:12.969Z","description":"First there was a crab, now there's a ghost","url":"https://time.com/3990437/mars-ghost-crab/","keywords":["Space","Newsfeed","NASA","Mars","Photo","images","woman"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltf67c149d8601131e/69885e792dce01069c9e4fd9/nasa-mars-woman.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltf67c149d8601131e/69885e792dce01069c9e4fd9/nasa-mars-woman.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"nasa-mars-woman-curiosity-rover","caption":"nasa-mars-woman-curiosity-rover","creditText":"JPL-Caltech/MSSS/NASA","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/space/","name":"Space"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3990437/mars-ghost-crab/","name":"You're Not Actually Seeing A Ghost on Mars"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"A Year in Space - Ep.1: Leaving Home","description":"A Year in Space - Ep.1: Leaving Home","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/6ookw4W2/poster.jpg?width=720","uploadDate":"2021-03-11T18:13:57.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/6ookw4W2.m3u8","embedUrl":"https://time.com/3990437/mars-ghost-crab/","duration":"PT13M31S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3990437/mars-ghost-crab/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
