'Snake Planet' Suddenly Appears, 'Ghostly' Tail 44 Times Larger Than Earth's

This unique phenomenon provides information about the formation and evolution of gas giant planets.

Exoplanet WASP-69 b, 160 light-years from Earth , is roughly the size of Jupiter and wraps around its parent star with a giant tail . (Photo: NASA)

The planet's tail is 44 times longer than Earth's diameter, formed from helium leaks caused by fierce stellar winds blowing out from its parent star. (Photo: EarthSky)

This phenomenon caused WASP-69 b to lose some of its mass, estimated to be 7 times that of Earth, since 2014. (Photo: Universe Space Tech)

Stellar winds, similar to solar winds, are the main cause of the planet's gas loss and the formation of its spectacular tail. (Photo: Combo Pop)

The planet's orbital period around its parent star is only 3.9 days, making it likened to "a great snake" in the universe. (Photo: Redazione SCImag SCI MEDIA)

The discovery was made using a new analysis of data from the WM Keck Observatory, Hawaii. (Photo: SPACE TODAY)
