The brief

NASA’s TESS mission has identified two large exoplanets characterized by their extremely low density. Reports describe the bodies as lighter than cotton candy, with physical properties likened to shaving foam.

International teams of astronomers are analyzing the pair to better understand their structural composition and the implications for broader cosmic evolution. Future reports are expected to clarify how these planets maintain their size and low density.

Scientific focus remains on what these specific discoveries reveal about the formation and development of planetary systems.

Quick answers

What makes these planets unique?

They are identified as 'super-puff' planets, meaning they possess an unusually low density compared to their large size, leading researchers to compare them to substances like cotton candy or shaving foam.

How were these planets discovered?

The planets were identified through data provided by NASA’s TESS mission.

What is the significance of this discovery?

According to the Financial Times, the twin planets provide new data points that researchers are using to study the processes of cosmic evolution.
