Researchers with Britain's Wide Angle Search for Planets consortium first discovered the planet WASP-12 b in 2008, orbiting extremely close to its parent star, Britain's Open University reported Tuesday.
The distance between the star and planet is so small that a superheated gas cloud has been boiled off the planet, some of which is feeding the star while some escapes into space, creating a veil or shroud that makes observation difficult by blocking many wavelengths of light.
Astronomers said a structure like this had never before been observed around a star.
"It's as though a veil has been drawn over the planet's demise," the Open University's Carole Haswell said.
The new observations were made with the Hubble Space Telescope using near-ultraviolet light.
