In a remarkable finding, astronomers have unveiled the discovery of an exoplanet that possesses a unique composition—likened to candy floss—yet it surpasses Jupiter in size.
Researchers have been baffled by WASP-193b describing it as “basically super fluffy,” given its unusually low density proportionate to its mass.
This exoplanet is believed to be composed primarily of hydrogen and helium, as documented in a study showcased in Nature Astronomy.
As the second least dense planet on record, WASP-193b’s mysterious characteristics are intriguing due to its dimensions, being approximately 50% larger than Jupiter.
“The planet is basically super fluffy” since it consists predominantly of light gases instead of solids, explains lead researcher Khalid Barkaoui from the Massachusetts Institute Of Technology (MIT).
A slew of additional empirical studies is required to unpack the enigma of its “fluffy” nature.
The extreme low density of WASP-193b has led some to suggest that it could ostensibly float on water, making it an exemplary subject for planetary formation and evolutionary studies.
While the existence of the exoplanet, situated beyond our solar system, was validated last year, it necessitated further rigorous observation with terrestrial telescopes to ascertain its physical properties accurately.
Residing approximately 1,200 light years from Earth, in which a light year equates to 5.8 trillion miles, WASP-193b orbits a sun-like star every six days or so—a factor which could be causing its atmosphere to expand significantly.

This unveiling of the soft-textured exoplanet coincides with the disclosure of a “super-Earth” residing within the Milky Way. This rocky planet, known as 55 Cancri e or Janssen, is situated only 41 light years from our home planet and boasts a diameter about double that of Earth’s.
According to Renyu Hu from NASA’s Jet Propulsion Laboratory and lead investigator of the study revealed in Nature, “The atmosphere could be dense with carbon dioxide or carbon monoxide and might contain other gases such as water vapor and sulfur dioxide.”
“While we cannot determine the exact atmospheric makeup presently, the planet is certainly uninhabitable,” claim scientists, pointing out that it’s excessively hot to support liquid water.
