Planet 'devoured in secret' by its own sun

(Phys.org)—A planet roughly 1.4 times the size of Jupiter is being consumed by its own star behind a shroud thanks to a magnesium veil absorbing all of certain light wavelengths, according to new observations by the Hubble ...

A hot potential habitable exoplanet around Gliese 163

A new superterran exoplanet (aka Super-Earth) was found in the stellar habitable zone of the red dwarf star Gliese 163 by the European HARPS team. The planet, Gliese 163c, has a minimum mass of 6.9 Earth masses and takes ...

Dramatic changes spotted in HD 189733b exoplanet atmosphere

(Phys.org) -- Astronomers using the NASA/ESA Hubble Space Telescope have seen dramatic changes in the upper atmosphere of a faraway planet. Just after a violent flare on its parent star bathed it in intense X-ray radiation, ...

'Extremely little' telescope discovers pair of odd planets

Even small telescopes can make big discoveries. Though the KELT North telescope in southern Arizona carries a lens no more powerful than a high-end digital camera, it's just revealed the existence of two very unusual faraway ...

Newfound exoplanet may turn to dust

Researchers at MIT, NASA and elsewhere have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris ...

Scientists help define structure of exoplanets

Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system.
