NASA announced that a single star relatively close to Earth is home to no fewer than seven Earthlike planets. If you're looking for extraterrestrial life, there may be no place better._ by [Feliz Solomon](https://time.com/author/feliz-solomon/) ## Feliz Solomon Feb 23, 2017 3:11 AM UTC  Google by [Feliz Solomon](https://time.com/author/feliz-solomon/) ## Feliz Solomon Feb 23, 2017 3:11 AM UTC NASA has just announced the [discovery ](http://time.com/4677103/nasa-announcement-new-solar-system/?xid=homepage)of seven previously unknown earth-size planets orbiting a single dwarf star, which scientists believe could be the best place to look for life, and the Google team could hardly contain its excitement. Thursday’s [animated Doodle](https://www.google.com/doodles/seven-earth-size-exoplanets-discovered) shows earth peering through a telescope to find its seven friendly neighbors, just 235 trillion miles away. Scientists said the newly discovered solar system, Trappist-1, is significant because three of its seven planets orbit in the “habitable zone”; their proximity to the system’s star suggests the right conditions for holding liquid water. The other four could also potentially be hospitable to living organisms. Researchers don’t yet know whether any of the planets are habitable, but they believe it’s promising. “This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” NASA administrator Thomas Zurbuchen said in a [statement](https://www.nasa.gov/press-release/nasa-telescope-reveals-largest-batch-of-earth-size-habitable-zone-planets-around). “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.” ## Transcript I'm excited to announce today, that Dr. Mikhail [ UNKNOWN ] and his team, have used our Spitzer space telescope to determine that are actually seven earth- sized planets orbiting the nearby Trappist- 1 star about 40 light years away What's more, as you can see in this illustration, is that three of these planets marked in green are in the habitable zone, where liquid water could pool on the surface. In fact with the right atmospheric conditions, there could be water on any of these planets. So for the first time we found as many terrestrial planets around a single star And that's the first time we've been able to measure in addition of both the masses and the radiai of these habitable earth sized planets. The discovery gives us a hint that finding a second earth It's not just a matter of if, but when. Now what is also exciting here about this system is that the planets are so close to each other. If you were on the surface of one of these planets, you would have A wonderful view on the other planets. We don't see them like we see Venus or Mars, like dots of light. But as you can see in the next illustration, you would see them really as you see the moon. You would see worlds which are very big. You could see the strictures on [ UNKNOWN ] walls. They would be as large as the moon, and even larger for some of them. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4679842/google-doodle-trappist-1-nasa/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4679842/google-doodle-trappist-1-nasa/"},"headline":"Google Celebrates the Discovery of Seven Earth-Sized Planets With This Stellar Doodle","datePublished":"2017-02-23T03:11:31.000Z","dateModified":"2026-08-04T07:47:34.492Z","description":"Scientists believe the new solar system could be hospitable to life","url":"https://time.com/4679842/google-doodle-trappist-1-nasa/","keywords":["Newsfeed","Google Doodle","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltef55d98bf9db288c/6988bb780a4a225b229cd054/seven-earth-size-exoplanets-discovered-6423181526040576-2-hp2x1.gif?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Feliz Solomon","jobTitle":null,"url":"https://time.com/author/feliz-solomon/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltef55d98bf9db288c/6988bb780a4a225b229cd054/seven-earth-size-exoplanets-discovered-6423181526040576-2-hp2x1.gif?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"seven-earth-size-exoplanets-discovered-6423181526040576-2-hp2x","caption":"","creditText":"Google","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":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4679842/google-doodle-trappist-1-nasa/","name":"Google Celebrates the Discovery of Seven Earth-Sized Planets With This Stellar Doodle"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"NASA Announces a Single Star Is Home to At Least 7 Earthlike Planets","description":"NASA announced that a single star relatively close to Earth is home to no fewer than seven Earthlike planets.
