A team of astronomers has discovered an Earth-sized planet orbiting around an ultra-cold red dwarf star with dimensions similar to Jupiter<\/strong>. As reported by Space.com<\/a><\/strong>, the red dwarf, located about 55 light-years away, is much less bright and colder than the Sun<\/strong>, and has half its temperature.<\/p>\n\n\n

With the scientific name of SPECULOOS-3 b<\/strong>, the discovery of this exoplanet<\/a> marks the second time a planetary system has been detected around a red dwarf<\/strong>, the first being the Trappist-1 system.<\/p>\n\n\n\n

The discovery of SPECULOOS-3 b is due to the SPECULOOS <\/strong>(Search for habitable Planets Eclipsing Ultra-cool Stars) project at the Paranal Observatory, located in the Atacama Desert, Chile. This project, named after a Belgian cookie, seeks rocky exoplanets around ultra-cool stars<\/strong>, such as red dwarfs and brown dwarfs, through infrared observations<\/strong>.<\/p>\n\n\n\n

The planet takes only 17 hours to orbit its star<\/strong>, which means that its year is extremely short compared to Earth. In addition, it is likely to be in a “tidal locking”, having one side perpetually illuminated by the sun and the other in eternal darkness<\/strong>. In this way, and despite its similarities to Earth in size, SPECULOOS-3 b differs significantly in its conditions, making it impossible to host liquid water on its surface<\/strong> due to the intense radiation it receives from its star.<\/p>\n\n\n

However, red dwarfs like the one hosting SPECULOOS-3 b are fascinating to scientists because of their longevity; they are the most common stars in the Milky Way and are expected to burn for more than 100 billion years<\/strong>, providing more time for life to develop in their planetary systems.<\/p>\n\n\n\n

Although SPECULOOS-3 b is not habitable, it remains an object of interest for research. In the future, the James Webb Space Telescope<\/a><\/strong> will examine it as part of a study to determine if planets near their stars can retain atmospheres<\/strong>.<\/p>\n\n\n
