That means they are not part of the group of planets like Earth, Mars, or Jupiter. Instead, they orbit other stars in faraway places.<\/p>\n\n\n\n<p>Since the 1990s, scientists have found over <strong>5,000 exoplanets<\/strong>! Some are rocky like Earth. Others are gas giants like Jupiter. A few are even in the <strong>habitable zone<\/strong>\u2014that\u2019s the perfect distance from a star where life could survive.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Are Biosignatures?<\/h2>\n\n\n\n<p>A <strong>biosignature<\/strong> is a clue that life might exist on a planet. These can be gases in the planet\u2019s atmosphere, like <strong>oxygen or methane<\/strong>. On Earth, these gases are made by living things\u2014like plants, animals, and even bacteria!<\/p>\n\n\n\n<p>So if scientists spot those same gases on an exoplanet, it could mean something is alive there, too.<\/p>\n\n\n\n<p>But it\u2019s not always simple. Sometimes gases like methane can come from volcanoes or chemical reactions\u2014not life. That\u2019s why scientists have to be extra careful.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do Scientists Look for Life?<\/h2>\n\n\n\n<p>Scientists use super powerful <strong>telescopes<\/strong> to study exoplanets. One of the coolest tools is the <strong>James Webb Space Telescope (JWST)<\/strong>. It\u2019s floating in space and can \u201csee\u201d very far away.<\/p>\n\n\n\n<p>Visit the site of the<a href=\"https:\/\/webbtelescope.org\/home\"> James Web Telescope<\/a> !<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"605\" src=\"https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-1024x605.webp\" alt=\"james-web-telescope\" class=\"wp-image-851\" srcset=\"https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-1024x605.webp 1024w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-300x177.webp 300w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-768x454.webp 768w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-370x219.webp 370w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-270x160.webp 270w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-570x337.webp 570w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope-740x437.webp 740w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/james-web-telescope.webp 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">james-web-telescope<\/figcaption><\/figure>\n\n\n\n<p>When a planet passes in front of its star, light from the star travels through the planet\u2019s atmosphere. Scientists look at that light to find out what gases are there. This is called <strong>spectroscopy<\/strong>\u2014like space detective work!<\/p>\n\n\n\n<p>If they find something like water vapor, carbon dioxide, or methane, it could be a hint of life.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Makes a Planet Habitable?<\/h2>\n\n\n\n<p>Not every planet can support life. Here\u2019s what scientists look for:<\/p><div class=\"de610b7b9de3e27210f105e73d9817c3\" data-index=\"1\" style=\"float: none; margin:0px 0 0px 0; text-align:center;\">\n<br>\r\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script>\r\n<!-- m4k blog body -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-client=\"ca-pub-0373877822875511\"\r\n     data-ad-slot=\"7178745461\"\r\n     data-ad-format=\"auto\"\r\n     data-full-width-responsive=\"true\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script>\r\n<br>\n<\/div>\n\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Water<\/strong> \u2013 All known life needs water.<\/li>\n\n\n\n<li><strong>Temperature<\/strong> \u2013 It can\u2019t be too hot or too cold.<\/li>\n\n\n\n<li><strong>Atmosphere<\/strong> \u2013 The planet needs a blanket of gases to keep things stable.<\/li>\n\n\n\n<li><strong>Chemicals<\/strong> \u2013 Elements like carbon and nitrogen are important.<\/li>\n<\/ul>\n\n\n\n<p>The planet must be in the \u201c<strong>Goldilocks zone<\/strong>\u201d\u2014not too close to its star and not too far. Just right!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Has Anyone Found Life Yet?<\/h2>\n\n\n\n<p>So far, <strong>no alien life has been discovered<\/strong>. But scientists have found <strong>possible biosignatures<\/strong>. In 2023, a planet called <strong>K2-18 b<\/strong> showed signs of a gas called <strong>dimethyl sulfide (DMS)<\/strong>. On Earth, only living things make that gas.<\/p>\n\n\n\n<p>That doesn\u2019t prove aliens are there, but it\u2019s a cool clue! Scientists are still studying K2-18 b to learn more.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Could We Visit These Planets?<\/h2>\n\n\n\n<p>Right now, it would take <strong>thousands of years<\/strong> to travel to even the <em>closest<\/em> exoplanet using today\u2019s technology. But that doesn\u2019t stop scientists from dreaming.<\/p>\n\n\n\n<p>One idea is to send <strong>tiny space probes<\/strong> at super high speeds. These would take pictures and send data back to Earth. It might take 20\u201330 years for the messages to return, but how awesome would that be?<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"577\" src=\"https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-1024x577.webp\" alt=\"k2-18b-2\" class=\"wp-image-852\" srcset=\"https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-1024x577.webp 1024w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-300x169.webp 300w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-768x433.webp 768w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-370x208.webp 370w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-270x152.webp 270w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-570x321.webp 570w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2-740x417.webp 740w, https:\/\/maps4kids.com\/blog\/wp-content\/uploads\/2025\/04\/k2-18b-2.webp 1163w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">k2-18b-2<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Can You Do to Learn More?<\/h2>\n\n\n\n<p>Want to be a space explorer one day?
