Only 41 light-years."},"content":{"rendered":"\n<h2 class=\"wp-block-heading\">In search of the \u201cGoldilocks zone\u201d<\/h2>\n\n\n\n<p>For life to exist on a planet in the form we know, liquid water is needed. The right conditions for it prevail in the so-called habitable zone \u2014 the region around a star where the temperature is neither too low nor too high. <strong>The right distance from the star, however, is not everything.<\/strong> To keep water from evaporating into space, a planet also needs an atmosphere with a sufficient greenhouse effect. For years, scientists have been looking for a planet similar to Earth that would meet these conditions.<\/p>\n\n\n\n<p>In 2016 the TRAPPIST-1 system was discovered, consisting of seven rocky planets orbiting a red dwarf. Three of them (TRAPPIST-1d, TRAPPIST-1e, and TRAPPIST-1f) lie within the system\u2019s habitable zone. <strong>Since 2022 JWST has been systematically studying these worlds in search of signs of an atmosphere<\/strong>. The latest analysis of the telescope\u2019s measurements, published in <em><a href=\"https:\/\/iopscience.iop.org\/article\/10.3847\/2041-8213\/adf42e\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Astrophysical Journal Letters<\/a><\/em>, suggests that one of these planets may indeed have one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What did the telescope see?<\/h2>\n\n\n\n<p>A team of scientists trained JWST on TRAPPIST-1e, a planet located at the center of the habitable zone. Although the data were initially contaminated by the star\u2019s own activity, after a year of painstaking analysis the <strong>researchers managed to isolate the signal coming from the planet<\/strong>. It is worth emphasizing that the entire TRAPPIST-1 system is only 41 light-years from Earth. On the cosmic scale, that is very close.<\/p>\n\n\n\n<p>What are the results? The analysis of the planet\u2019s emitted and reflected light indicates that the world <strong>possesses a so-called secondary atmosphere containing heavy molecules<\/strong> (for example methane or nitrogen). So far astronomers have carried out four observations of TRAPPIST-1e. They stress that this is not enough to prove the planet\u2019s atmospheric composition beyond all doubt. The data to date, however, clearly suggest that it could be hospitable to life.<\/p>\n\n\n\n<p><strong>Worth reading: <\/strong><a href=\"https:\/\/holistic.news\/en\/mars-discovery\/\" target=\"_blank\" rel=\"noreferrer noopener\">Mars discovery: InSight reveals a game-changing secret<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">An earth-like planet lies surprisingly close<\/h2>\n\n\n\n<p>If TRAPPIST-1e really has an atmosphere, it would be the first such discovery in history! <strong>A thick atmosphere could allow liquid water to exist on its surface<\/strong>. To confirm this, scientists must measure the concentrations of greenhouse gases such as carbon dioxide and methane. Observations with JWST are ongoing and will allow a definitive answer as to whether TRAPPIST-1e is truly a \u201csecond Earth.\u201d Further analyses from astronomers should appear over the next 2 years.<\/p>\n\n\n\n<p>Just<strong> 41 light-years from us<\/strong> there may be a world that meets the basic conditions for life to arise. <strong>Upcoming data could prove groundbreaking.<\/strong> Scientists still do not rule out, however, that TRAPPIST-1e may be another dead rock like the millions found across the cosmos. Are we separated from discovering life beyond Earth by only a few years \u2014 and by the confirmation that this nearby world is indeed an earth-like planet?<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><em>Read the original article:<\/em> <a href=\"https:\/\/holistic.news\/planeta-podobna-do-ziemi\/\" target=\"_blank\" rel=\"noreferrer noopener\">Odkryli niezwyk\u0142\u0105 planet\u0119.
