The planet is about twice the size of Earth\u2019s diameter, but it\u2019s the smallest exoplanet found to have water vapor in its atmosphere.<\/p>\n<p>Even as water is essential to sustaining life, there is unlikely to be any on this exoplanet as it has searing hot temperatures according to Thursday\u2019s report. The exoplanet is as hot as Venus&#8212;burning at about 800 degrees Fahrenheit (426 degrees Celsius) it is an inhospitable world. But the planet\u2019s existence could be proof that there are other planets with water-rich atmospheres in our galaxy, according to NASA.<\/p>\n<p>&#8220;This would be the first time that we can directly show through an atmospheric detection, that these planets with water-rich atmospheres can actually exist around other stars,&#8221; said Bjo\u0308rn Benneke of the Trottier Institute for Research on Exoplanets at Universite\u0301 de Montre\u0301al. &#8220;This is an important step toward determining the prevalence and diversity of atmospheres on rocky planets.&#8221;<\/p>\n<p>Benneke adds that the planet could be half water and half rock, and that there could be a lot of \u201cwater vapor on top of some smaller rocky body\u201d.<\/p>\n<p>&#8220;Water on a planet this small is a landmark discovery,&#8221; added Laura Kreidberg of Max Planck Institute for Astronomy in Heidelberg, Germany. &#8220;It pushes closer than ever to characterizing truly Earth-like worlds.&#8221;<\/p>\n<p>Astronomers who stumbled upon GJ 9827d are not yet sure if it has just a small amount of water vapor, or if the its atmosphere is made up of mostly water. But so far they have two theories regarding its make-up: either the planet is still holding onto a hydrogen rich atmosphere enriched with water like Neptune. Or the planet could be a warmer version of Jupiter\u2019s moon Europa, which has twice as much water as Earth underneath its crust, according to NASA.<\/p>\n<p>&#8220;Observing water is a gateway to finding other things,&#8221; said Thomas Greene, astrophysicist at NASA&#8217;s Ames Research Center in California&#8217;s Silicon Valley.<\/p>\n<p>&#8220;This Hubble discovery opens the door to future study of these types of planets by NASA&#8217;s James Webb Space Telescope. JWST can see much more with additional infrared observations, including carbon-bearing molecules like carbon monoxide, carbon dioxide, and methane. Once we get a total inventory of a planet&#8217;s elements, we can compare those to the star it orbits and understand how it was formed,&#8221; Greene added.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>For More News And Analysis About <span style=\"color: #ff6600\">Sierra-Leone<\/span> Follow <span style=\"color: #ff6600\">Africa-Press<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Sierra-Leone.
