The detection of biosignatures on an exoplanet depends on the ability to study its atmosphere, but current telescopes are not large enough to achieve the resolution needed to do this for small, rocky planets. The newly studied planetary system, called L 98-59 after its star, is an attractive target for future observations of exoplanet atmospheres. Its orbits a star only 35 light-years away and has now been found to host rocky planets, like Earth or Venus, which are close enough to the star to be warm.<\/p>\n<p>With the contribution of ESO\u2019s VLT, the team was able to infer that three of the planets may contain water in their interiors or atmospheres. The two planets closest to the star in the L 98-59 system are probably dry, but might have small amounts of water, while up to 30% of the third planet\u2019s mass could be water, making it an ocean world.<\/p>\n<p><figure id=\"attachment_24225\" aria-describedby=\"caption-attachment-24225\" style=\"width: 500px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.eso.org\/public\/images\/eso2112b\/\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"24225\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=24225\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2021\/08\/eso2112b1.jpg\" data-orig-size=\"700,382\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;ESO\/L.
