James Webb Space Telescope discovers ‘super-Venus’ exoplanet GJ 1214 b with rare composition 48 light-years away

The universe still contains many mysterious places, but with every discovery made, our horizons expand towards understanding the vast expanse of cosmos. One of such discoveries made through the

James Webb Space Telescope

was a planet far away from everything familiar. At a distance of 48 light-years in the constellation Ophiuchus lies the

exoplanet GJ 1214 b

, and its dense carbon dioxide atmosphere categorizes it beyond conventional planetary identification. This reveals much about the evolution of the planets and at the same time, opens the windows for new exploration into the formation and diversification of the worlds beyond.

GJ 1214 b, absolutely a planet with an unusual structure. It occupies a rare middle ground between Earth-like rocky planets and Neptune-like ice giants, but it’s neither hydrogen-rich nor dominated by water as thought to be the case. The atmosphere of this planet is primarily made up of carbon dioxide. Equipped with high spectroscopy, among other advanced features, the James Webb Space Telescope enabled scientists to study the atmosphere of the planet by studying starlight passing through its clouds. Data collected in this process called for careful analysis, according to researcher Kazumasa Ohno, opening up new knowledge on the exoplanet atmosphere.

Often called a “super-Venus,” GJ 1214 b shares some similarities with Venus but has extreme carbon dioxide levels that indicate a very different formation history. This discovery challenges previous notions about the structure and origin of mid-sized planets. The thick atmosphere of the planet may be the result of highly intense geological activity, which raises questions about evolution between a rocky world and a gas giant. The study of GJ 1214 b assists the scientists to formulate the current models in the formation of planets and to understand the processes which shape such unique planets.

The discovery of GJ 1214 b verifies the strength of James Webb Space Telescope such that it helps extend our knowledge beyond what was ever considered for far-off worlds. To analyze such distant exoplanets, high-level analysis and innovative approaches are necessary. Hence, it is possible to study planets that otherwise would be considered unthinkably unreachable. Avenues will be opened for further exploration of similar exoplanets, which will eventually fill up our understanding of the vast and complex universe. GJ 1214 b continues to remind about the great variety of planetary types in space.
