Astronomers have discovered two gigantic planets that are surprisingly lighter than cotton candy, with densities comparable to shaving foam. These super-puffs, orbiting a star 1,110 light-years away, are the largest exoplanets found to have less density than cotton candy. They are the lightest known planets of their size, according to George Dransfield of the University of Oxford.
The two planets were detected by NASA’s Tess satellite and studied using telescopes on Earth to determine their density. They orbit a star in the southern constellation Volans and are thought to be mostly hydrogen and helium. The planets have unusually long orbits, with one taking 139 days and the other taking 232 days to circle the host star.
Giant Exoplanets
These fluffy, wispy worlds are probably white or blue, depending on whether the skies there are cloudy. The discovery of these planets is significant, as they represent a puzzle for scientists to solve about how giant planets like Jupiter and super-puffs form. The researchers suspect that super-puffs form around the disk of gas and dust around a newborn star where there is more gas than dust.
The discovery of these planets sheds new light on the formation of planets outside our solar system. With nearly 6,300 confirmed exoplanets, fewer than 40 are super-puffs, making them a rare and intriguing find. By studying exotic systems containing rare planet types, scientists can learn more about planet formation and our place in the cosmos.
Implications and Next Steps
The study of these planets will continue with follow-up observations by NASA’s Webb Space Telescope to confirm their chemical makeup. Jon Jenkins, the science lead for the Science Processing Operations Center at NASA’s Ames Research Center, notes that these planets are interesting to study because they were not expected to exist. The discovery of these super-puffs will help scientists better understand the formation of giant planets and the diversity of planetary systems.
The discovery of these giant planets lighter than cotton candy is a significant find, expanding our knowledge of the universe and the many mysteries that remain to be solved. As scientists continue to explore and study the cosmos, they may uncover even more surprising and unexpected discoveries that challenge our understanding of the universe and its many wonders.
