Low-density planet presents big challenge WASP-193b, which researchers think is made up of mostly hydrogen and helium, was a huge puzzle for researchers to piece together.

Astronomers have just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant Sun-like star. An international team led by researchers from the EXOTIC Laboratory of the ...

Scientists have discovered a planet that they said could float in a bathtub if you could get one large enough. The planet is about 580 light-years away from us and is orbiting a red dwarf star in ...

To their great surprise, the accumulated measurements revealed an extremely low density for the planet. Its mass and its size, they calculated, were about 0.14 and 1.5 that of Jupiter, respectively.

Another fluffy planet was discovered in 2017, WASP-107b, which is roughly the size of Jupiter with only about 12% of its mass. But WASP-193b is an enigma all its own, the researchers say.

Astronomers have discovered an exoplanet larger than Jupiter but incredibly lightweight, similar to cotton candy. The planet, named WASP-193b, has an unusually low density compared to gas giants ...

Astronomers have recently discovered a planet with a density similar to cotton candy, floating 1,200 light-years away from Earth. Dubbed WASP-193b, this giant among giants has baffled scientists ...

A gas giant exoplanet [right] with the density of a marshmallow has been detected in orbit around a cool red dwarf star [left] by the NASA-funded NEID radial-velocity instrument on the 3.5-meter ...

A planet with the density of a marshmallow has been discovered by scientists. The planet, identified as TOI-3757 b, is the fluffiest ever found, orbiting around a cool red dwarf star approximately ...

This planet is incredibly low-density. NASA, ESA, CSA, Ralf Crawford STScI. Additionally, the lower methane levels and higher temperatures indicate that WASP-107 b has an exceptionally ...
