NASA launches TESS satellite to search for alien worlds

The $337m planet-hunting space telescope launched on Wednesday from Cape Canaveral in Florida, is the agency’s most ambitious quest yet to scour planets' atmospheres for any life.

    The search for alien worlds has taken another big step with the launch of NASA's latest satellite.

    The Transiting Exoplanet Survey Satellite, or TESS, is the agency's most ambitious attempt in the search for worlds like our own.
