There are some odd things being spotted off-world that have left experts shaking their heads.

In a story that appeared in Discovery News, NASA scientists are said to be baffled about a mystery object that suddenly appeared in a photo received from the Opportunity Rover on Mars.

'After a decade of exploring the Martian surface, the scientists overseeing veteran rover Opportunity thought they’d seen it all. That was until a rock mysteriously “appeared” a few feet in front of the six wheeled rover a few days ago. News of the errant rock was announced by NASA Mars Exploration Rover lead scientist Steve Squyres of Cornell University at a special NASA Jet Propulsion Laboratory “10 years of roving Mars” event at the California Institute of Technology (Caltech), Pasadena, Calif., on Thursday night. The science star-studded public event was held in celebration of the decade since twin rovers Spirit and Opportunity landed on the Red Planet in January 2004.' - Ian O'Neill

 

In other weird news, the folks over at Tech And Gadget News are wondering if one of those giant 'flying triangle UFO's' have been caught by Google Earth by a crater on the Moon:

There are probably rational explanations for these anomalies, what do you think they are?
