Superman's x-ray vision has nothing on space-based super ‘scopes Chandra and XMM Newton, which have detected a distant exoplanet passing in front of its star for the very first time in high-energy x-rays.
The planet that's been spotted doesn't resemble the fictional Krypton, though, nor is it anything like Earth: exoplanet HD 189733b is a hot Jupiter - a bloated, broiling gas giant racing through the searing glow of its parent star, locked in a 2-day-long orbit 30 times closer than we are from our sun.
The overheated exoplanet orbits HD 189733, a sun-like star located 63 light-years away in the northern constellation Vulpecula.

Of course, exoplanets have been observed many times before using various methods, such as detecting the faint reduction in a star's apparent brightness caused by a passing planet and identifying the slight wobble in a star's position resulting from the gravitational tug of orbiting worlds. But this is the first time that an exoplanet's transit has been observed in x-ray wavelengths.
